IEEE 802.11 a/g/p Transceiver

Hi!

This an IEEE 802.11 a/g/p transceiver for GNU Radio that is fitted for operation with Ettus N210s and B210s. Interoperability was tested with many off-the-shelf WiFi cards and IEEE 802.11p prototypes. The code can also be used in simulations.

Development

Like GNU Radio, this module uses maint branches for development. These branches are supposed to be used with the corresponding GNU Radio branches. This means: the maint-3.7 branch is compatible with GNU Radio 3.7, maint-3.8 is compatible with GNU Radio 3.8, etc.

Installation

Dependencies

GNU Radio

There are several ways to install GNU Radio. You can use

• pybombs
• pre-compiled binaries
• from source

gr-foo

I have some non project specific GNU Radio blocks in my gr-foo repo that are needed. For example the Wireshark connector. You can find these blocks at https://github.com/bastibl/gr-foo. They are installed with the typical command sequence:

git clone https://github.com/bastibl/gr-foo
cd gr-foo
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

Installation of gr-ieee802-11

To actually install the blocks do

git clone https://github.com/bastibl/gr-ieee802-11
cd gr-ieee802-11
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

Adjust Maximum Shared Memory

Since the transmitter is using the Tagged Stream blocks it has to store a complete frame in the buffer before processing it. The default maximum shared memory might not be enough on most Linux systems. It can be increased with

sudo sysctl -w kernel.shmmax=2147483648

OFDM PHY

The physical layer is encapsulated in a hierarchical block to allow for a clearer transceiver structure in GNU Radio Companion. This hierarchical block is not included in the installation process. You have to open /examples/wifi_phy_hier.grc with GNU Radio Companion and build it. This will install the block in ~/.grc_gnuradio/.

Check message port connections

Sometime the connections between the message ports (the gray ones in GNU Radio Companion) break. Therefore, please open the flow graphs and assert that everything is connected. It should be pretty obvious how the blocks are supposed to be wired. Actually this should not happen anymore, so if your ports are still unconnected please drop me a mail.

Python OpenGL

If you want to run the receive demo (the one that plots the subcarrier constellations), please assert that you have python-opengl installed. The nongl version of the plot does not work for me.

Run volk_profile

volk_profile is part of GNU Radio. It benchmarks different SIMD implementations on your PC and creates a configuration file that stores the fastest version of every function. This can speed up the computation considerably and is required in order to deal with the high rate of incoming samples.

Calibrate your daughterboard

If you have a WBX, SBX, or CBX daughterboard you should calibrate it in order to minimize IQ imbalance and TX DC offsets. See the application notes.

Checking your installation

As a first step I recommend to test the wifi_loopback.grc flow graph. This flow graph does not need any hardware and allows you to ensure that the software part is installed correctly. So open the flow graph and run it. If everything works as intended you should see some decoded packets on the console.

Troubleshooting

If GRC complains that it can't find some blocks (other than performance counters and hierarchical blocks) like

>>> Error: Block key "ieee802_11_ofdm_mac" not found in Platform - grc(GNU Radio Companion)
>>> Error: Block key "foo_packet_pad" not found in Platform - grc(GNU Radio Companion)

Most likely you used a different CMAKE_INSTALL_PREFIX for the module than for GNU Radio. Therefore, the blocks of the module ended up in a different directory and GRC can't find them. You have to tell GRC where these blocks are by creating/adding to your ~/.gnuradio/config.conf something like

[grc]
global_blocks_path = /opt/local/share/gnuradio/grc/blocks
local_blocks_path = /Users/basti/usr/share/gnuradio/grc/blocks

But with the directories that match your installation.

Usage

Simulation

The loopback flow graph should give you an idea of how simulations can be conducted. To ease use, most blocks have debugging and logging capabilities that can generate traces of the simulation. You can read about the logging feature and how to use it on the GNU Radio Wiki.

Unidirectional communication

As first over the air test I recommend to try wifi_rx.grc and wifi_tx.grc. Just open the flow graphs in GNU Radio companion and execute them. If it does not work out of the box, try to play around with the gain. If everything works as intended you should see similar output as in the wifi_loopback.grc example.

Ad Hoc Network with WiFi card

• The transceiver is currently connected to a TAP device, i.e. is a virtual Ethernet interface. Therefore, we have no WiFi signaling like association requests and hence, the transceiver can not "join" an ad hoc network. You have to make some small changes to the kernel in order to convince you WiFi card to send to this hosts nevertheless.
• The transceiver can not respond to ACKs in time. This is kind of an architectural limitation of USRP + GNU Radio since Ethernet and computations on a normal CPU introduce some latency. You can set the number of ACK retries to zero and handle retransmits on higher layers (-> TCP).
• RTS/CTS is not working for the same reason. You can however just disable this mechanism.
• Currently, there is no CSMA/CA mechanism, but this can be implemented on the FPGA.

Troubleshooting

• Please check compile and installation logs. They might contain interesting information.

• Did you calibrate your daughterboard?

• Did you run volk_profile?

• Did you try different gain settings?

• Did you close the case of the devices?

• Did you try real-time priority?

• Did you compile GNU Radio and gr-ieee802-11 in release mode?

• If you see warnings that blocks_ctrlport_monitor_performance is missing that means that you installed GNU Radio without control port or performance counters. These blocks allow you to monitor the performance of the transceiver while it is running, but are not required. You can just delete them from the flow graph.

• The message

  You must now use ifconfig to set its IP address. E.g., $ sudo ifconfig tap0 192.168.200.1

is normal and is output by the TUN/Tap Block during startup. The configuration of the TUN/TAP interface is handled by the scripts in the apps folder.

• Did you try to tune the RF frequency out of the band of interest (i.e. used the LO offset menu of the flow graphs)?
• If 'D's appear, it might be related to your Ethernet card. Assert that you made the sysconf changes recommended by Ettus. Did you try to connect you PC directly to the USRP without a switch in between?

gr-ieee802-11's Issues

Can't receive data in wifi_rx

Hi Bastian,

When trying wifi_tx and wifi_rx samples using two usrp N210 with the following configuration:
sampling rate : 200 KHz (higher sampling rates shows DDD and UUUU on thelaptops)
network: two usrps and laptops connected to same switch (address of sender/receiver is specified using the addr=ip specifier)

The receiver doesn't get data. The attached log shows the following:

• Warning: starting to receive new frame before old frame was complete
• checksum wrong -- dropping

Also, I tried the rx_demo.sh in the "/apps" folder. Wireshark can't see data.

What could be the reason behind this?

attached logs of sender, receiver and also detailed device configuration (using uhd_usrp_probe command).

receiver_log.txt
sender_log.txt
usrp_probe.txt

Abdo

Using the graph with HackRf

Hello,
did anyone used the transceiver with HackRf as signal source?I am trying to capture wifi signals with Hack Rf and wanted to use this but I could not calibrate it with 5.24 GHz wifi frequency. It overloads and cannot decode anything.Any help will be appreciated. Thanks

swig problem: 'Import "import ieee802_11" failed.'

Hi,

i'm running gnuradio version 3.7.5-5 installed from Debian testing. Building gr-foo and gr-ieee802-11 works without errors. When importing the ieee802_11 module from python, it is working:

$ python -v
...
>>> import ieee802_11
import ieee802_11 # directory /usr/lib/python2.7/dist-packages/ieee802_11

>>> ieee802_11.BPSK_1_2
0
>>> 

Yet, when using it in gnuradio, it keeps telling me that the import failed. When opening the wifi_phy_hier.grc I get a couple of errors like this:

Error 3:
Block - encoding - Parameter(parameter):
  Param - Value(value):
    Value "ieee802_11.BPSK_1_2" cannot be evaluated:
    name 'ieee802_11' is not defined

For further debugging, I built a minimal gnuradio example consisting of a simple import block for the module. To verify the module is actually loading etc. I started gnuradio like this:

$ /usr/bin/python -v //usr/bin/gnuradio-companion
...
import ieee802_11 # directory /usr/lib/python2.7/dist-packages/ieee802_11

dlopen("/usr/lib/python2.7/dist-packages/ieee802_11/_ieee802_11_swig.so", 102);
import ieee802_11 # directory /usr/lib/python2.7/dist-packages/ieee802_11
# /usr/lib/python2.7/dist-packages/ieee802_11/__init__.pyc matches /usr/lib/python2.7/dist-packages/ieee802_11/__init__.py
import ieee802_11 # precompiled from /usr/lib/python2.7/dist-packages/ieee802_11/__init__.pyc
# /usr/lib/python2.7/dist-packages/ieee802_11/ieee802_11_swig.pyc matches /usr/lib/python2.7/dist-packages/ieee802_11/ieee802_11_swig.py
import ieee802_11.ieee802_11_swig # precompiled from /usr/lib/python2.7/dist-packages/ieee802_11/ieee802_11_swig.pyc
dlopen("/usr/lib/python2.7/dist-packages/ieee802_11/_ieee802_11_swig.so", 102);
Showing: "/tmp/untitled.grc"

However, the import block keeps telling me:

    Param - Import(import):
        Import "import ieee802_11" failed.

For further debugging, I was hand-editing the module files. It turned out that the import error in gnuradio only occurs if _ieee802_11_swig.so is imported - which doesn't raise any error on the python command line. However, without _ieee802_11_swig.so, all the contents of the module are missing ;)

A screenshot of my minimal error example can be found here:

Do you have any idea how I can get rid of this import error? The python path is correct and all modules are actually found...

Best,
Jiska

Correlation Output Initialization?

I noticed that the autocorrelation output in the receiver chain appears to have an initialization phase (oscillator stabilization?) that expands above .56, and doesn't settle until about 1e7 samples. The other high spikes are packets that were being detected from a COTS 802.11p radio.

I added some code to ofdm_sync_short.cc to tell me when initialization was complete before the search state was entered. I'm interested to see if anyone else thinks this would be useful. This just makes sure that the initialization phase is complete before the receiver starts detecting packets.

/*This is the first state when the flowgraph starts. 
It is never entered into again, once it transitions the receiver to the SEARCH state.*/
case INIT: {
            int k;
            for(k = 0; k < ninput_items[2]; k++) {
                d_initSamples++;
/*the autocorrelation value must be low, and 1e7 must have been received 
since starting the flow graph.*/
                if(in_cor[k] < d_threshold && d_initSamples > 1e7) {
                    dout << "Initialization complete!" << std::endl;
                    d_state = SEARCH;
                    d_initSamples = 0;
                    break;
                }
            }
            consume_each(k);
            return 0;
        } 

I was surprised that this initialization phase is captured by the autocorrelation output, which prompted me to add this code to my build. The code is very helpful.

The values for d_threshold, d_initSamples, and the GAIN in the flow graph may need to be adjusted depending on each users set-up, perhaps 1e7 could be a block parameter which states how many samples must have been received from the device since the flowgraph has started. This should also be turned off if users are not using an SDR, because this INIT state is not needed for simulations.

why you use these daughterboards

Hello bastibl,

I'm confused about the reason(s) you used daughterboards. As far as I know, the N210 can also work on up to 6 GHz which is compatible for wifi.

Best regards,

Bojun

CSI

Hi,

I have a problem understanding the CSI extraction. It seems to me that the input of the frame decoding is the 48 data subcarrier, which is calculated in ls.cc as vector symbol. The d_H contains the 64 subcarrier. So d_H should contain the data subcarrier symbol. But why in ls.cc for the data subcarrier in d_H is different from symbol?

Thanks in advance.

wifi_phy_heir error: ieee802_11.wifi_signal_field() - Macports install

[OS X Yosemite 10.10.1, GNURadio v3.7.5.2]
From a fresh Macports (/opt/local/ path) installation I follow the instructions and try to open the wifi_phy_heir example.

It fails to run as the header_formatter variable value, ieee802_11.wifi_signal_field(), raises an error:

There is a mini-discussion of a workaround here:

Over the air USRP radios communication - message not transmitted

Hi,

Loopback works fine for me. I am now trying to communicate between two USRP N210s with WBX.

While running Rx and Tx separately I get 'U' on the console repeatedly. I increased the shared-memory to 2GB. I modified the transmitter USRP sink and receiver USRP source to have a carrier frequency of 900MHz. I also set the Frame Equalizer to 900MHz at the receiver. At the receiver, I see a series of 'D' in the console.

Transmitter

Receiver:

Please let me know how I might be able to fix this.

Thanks!

Overflow

Hi Bastian,
I am using the following setup:

• Ubuntu 16.04.1 LTS 64 bit
• Intel Core i7-3770 [email protected] x 8 and 16 GB of RAM;
• Ettus USRP N201 with CBX daughterboard;
• GnuRadio v3.7.10.1;
• I am trying to use "wifi_rx.grc" to receive data from an 802.11g AP;
• Bandwidth = 20 MHz;
• Central frequency = 2.437 GHz (channel 6);
• Sample rate 20 MHz;
• I have already properly set the UDP buffer size (rmem and wmem) and the max shared memory (shmmax);
• I have also set the right priority for real time scheduling;

Using this setup I experience the overflow condition, i.e. uhd prints a lot of "D"s while the receiver is running.
Do you have some hints/suggestions?
Do you think that by using this hardware I cannot have a receiver which works in real time?.

Thanks a lot in advance,
Simone

OFDM 256-QAM

Good Morning.
I found your work very interesting and i have tried of modify your code for implementig 256-QAM, but i have trouble.
Can you help me about 256 QAM, it's possibile to update this modulation?

Performance question & state of SDR wifi

I'm interested in this project and was wondering what the practicality of it is for a production deployment in the future.

Do you have any insight into the performance of SDR wifi vs an off the shelf router?

For OTA, are you able to achieve 802.11g speeds that are on par with common routers?

For hardware, I assume the hardware running SDR wifi would need significantly higher specs. Any insight into what those look like or are we still too early in the development of this technology?

How far out is 802.11n/ac? Are there major new challenges in expanding to those or is it merely an issue of time and materials.

Thanks!

bad results

I'm running the project in Gnu Radio, and the loopback worksfine for every modulation scheme. But when I do the case of a Tx and Rx (I'm using 2 laptops, one Rx and the other Tx and 2 USRP connected to each one of the laptops) I get bad results.
I made sure the USRPs are connected to each laptop and pinged them, so they're sending packets but the points in the constallation scheme are messed up, even when I change gain or any other parameter I still have bad results.
Do we need to change the daughterboard?
I'm using OS ubuntu 16.04 LTS . HW USRP N210, Gnu Radio 3.7.9, BW 10 Mhz and freq 5.89 Ghz (same parameters as in the project )

Thank you in advance

Problem compiling

Hi! I get the following error while compiling

/home/rwnobrega/Projects/gr-ieee802-11/lib/utils.h:32:64: error: expected ‘;’ before ‘}’ token
 #define mylog(msg) do { if(d_log) { GR_LOG_INFO(d_logger, msg) }} while(0);

Putting the ‘;’ before ‘}’ apparently fixes the problem.

Asynchronous message buffer overflow due to back pressure

Hi Bastian,

Host System Details:

OS: Ubuntu 14.04LTS 64-bit
Processor: Intel Xeon E3-1575M v5 @ 3GHz x 8
Memory: 31.1GB
Graphics: Nvidia Quadro M2000M/PCIe/SSE2
SSD: 500GB M.2 PCIe
Kernel: 3.19.0-80-generic

SDR Hardware and Software Details:

2x Ettus USRP B205mini-i (USB3)
UHD_3.11.0.git-94-g5964adcd
GNU Radio Companion v3.7.10.1-237-g81e7af7b
Freshly installed via PyBOMBS

I have modified your original "wifi_transceiver" example to work with my two Ettus USRP B205mini-i (see the flowchart below) and have added Control Port for performance monitoring. For testing my SDRs are connected using a 30dB attenuation loopback cable. I currently just have it set up to send from one and receive on the other.

I am running into an issue where the OFDM Carrier Allocator block in the transmitter-half of the WIFI PHY Hier is acting as a bottleneck when transmitting messages. It prevents me from strobing messages with a period smaller than around 5ms before I receive the message

gr::log :WARN: tpb_thread_body - asynchronous message buffer overflowing, dropping message

Looking at the Control Port Performance Monitor output below, I can see a considerable proportion (around 80%) of the computation time being spent on the ofdm_carrier_allocator_cvc block. Eventually its input buffer fills to 100%, applying back pressure on the adjoining buffers.

Perhaps unrelated, I have also noticed from the edge colours that the receiver side is consistently allowing frames to progress through to the WIFI Sync Long block from the WIFI Sync Short. Is it worth me adjusting this block's threshold?

I have followed your setup guide by enabling real-time scheduling (this removed most instances of 'O' overruns I previously encountered in 10MHz and 20MHz bandwidth modes) and running volk_profile. This last test is where I found some interesting results. Below I have attached some highlights which show considerable time (anything over 1000ms) being taken for certain operation types (especially volk_32fc_s32f_power_32fc). My machine was classified as avx2_64_mmx_orc. Possibly this ties into the bottleneck? I have also run volk_profile on my i7-6500U @ 2.50GHzx4 system running Ubuntu 16.10 and found similar/worse results.

If I want to make use of the 20MHz bandwidth and potential 54Mbps connection speed of this standard, surely I would need to be able to send messages considerably more often than every 10ms? Or am I missing something obvious? For testing I was using varying payload sizes all the way up to 1499 Bytes and periods as low as 1ms before the overflow occurs (theoretically 12Mbps?). I originally tested a Socket PDU UDP server and python script instead of the message strobe and found similar results.

Hopefully you can help me understand what is going on. I look forward to your reply and questions. Thanks!

gr-ieee802-11 outer coder

Hi,
Hi, I've been setting up gr-ieee802-11 on a Linux with gnuradio 3.7.10.1.
I have added an outer coder in gr-ieee802.11 with gr_modtool add and make the xml file with gr_modtool makexml.
the block is available in gr-ieee802-11.

Right now I'm just trying to build "/examples/wifi_phy_hier.grc" as detailed on the main Github page. However I get the following errors in Gnuradio-companion:

Error 0:

I'm guessing there is something I did wrong in setting everything up, but I can't figure out what. Any ideas?

Regarding CSMA/CA Mechanism

Is the a CSMA/CA mechanism in your gr-ieee802.11 code which can be implemented on USRP and general purpose PC

Do You Have Some Related Docs, Manual or Papers?

Hi Bastibl,

I'm trying to use your code and do some modifications so that it can work on NI USRP 2920 with Vert 400 antennas. However, I'm a little bit confused about why you chose the values of parameters and variables. Is there any document, manual or paper that describe this project?

Thanks,

Bojun

Problems using osmosdr_source/hackrf to RX

Hi, thanks for this great project. I tried to use osmosdr_source instead of uhd - RX only - I see alot of hex data aka possible packets from OFDM_Decode_MAC (Debug enabled) but all of seem to have a wrong checksum:

Decode MAC: frame start...
received complete frame - decoding
coding rate 0.5
checksum wrong  -- dropping).

If I use wifi_rx I also don't see any error rate information - and therefore I think this is related to the mentioned problems. Frame Error Rate: None

• I tried different sample rates, offsets and chan_est settings and antennas
• wifi_loopback works AND shows low error rate (instead of None)
• increased shared mem and volk_profile - done

so I am a little bit out of ideas - I will go on reading source and placing debug console output about checksum calculation etc.

ps. wireshark file is empty 24bytes

is it possible to use osmosdr_source/hackrf (RX-only) at all? any other ideas / of course I am willing to read source and produce PRs.

thanks aggain

Great project! I have yet to try compiling it yet, but have you tried submitting any of your blocks to the GNURadio project? Once like your 802.11 and Wireshark blocks?

Can't ping from one pc to another...

I have the wifi_transceiver.grc running on both systems which are connected to usrps but when I configure the tap0 ip address to 192.168.200.1 on host1 and 192.168.200.2 on host2 I am unable to ping from one system which is connected to B200 mini usrp to another system which is connected to another B200 mini usrp. I also followed the nic.sh script but it didn't work.

It would be great to get some help

Thank you

gr-ieee80211 and the bladeRF

Hello,

I have modified the wifi_rx example to use the osmocom source instead of the uhd source. The application runs but I receive very little Wi-Fi data in wireshark. The only packets I actually can decode are RTS and CTS with the occasional Ack.

I never receive any Beacons or other packets. What would cause this to happen?

Thank in advance

wifi_loopback.grc issue

Hi,

I am trying to run wifi_loopback.grc. However, I notice nothing on the command line about the transmitted message and the plot is blank. Following is the output :

Using Volk machine: sse4_a_64_orc
OFDM MAPPER: encoding: 0
set_min_output_buffer on block 31 to 96000
set_min_output_buffer on block 33 to 96000

set_min_output_buffer on block 36 to 96000
set_min_output_buffer on block 39 to 96000
set_min_output_buffer on block 50 to 96000

The scope plot looks blank like this:

I am in the master branch, and wifi_phy_hier was built before executing the loopback.

Please let me know what might be the issue, and how I might be able to fix this.

ubuntu 16.04LTS, cannot find some of the blocks after installation

ieee802_11 module in wifi_phy_hier

Hi,

I tried opening wifi_phy_hier via GRC and I noticed it red-ed as a missing module. I set PYTHONPATH by looking at the makefile as : "export PYTHONPATH=/usr/local/lib/python2.7/site-packages/". However my GRC now crashes as:

Loading: "/Users/avinash/usrp/gr-ieee802-11/examples/wifi_phy_hier.grc"
Fatal Python error: PyThreadState_Get: no current thread
Abort trap: 6

When I do /usr/bin/python2.7
import ieee802_11

The import is successful

However, the python which GRC is picking is /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python

I think there's a Python mismatch. Please let me know if there's any quick way to fix this ?

Thanks!

Implementation gr-802.11 to Hackrf one Hardware

Hi i have a question about gr-802.11,
is it possible implement this tool through Hackrf one instead UHD?

Thanks in advance

LED Status of USRP

Hi Bastian,

When I run the code for TX, the TX LED of USRP blinks with a dim light which is a different status from the status when I run LabView code. What's more, when I run the RX code, I get solid LED on for RX. What was LED status when you ran the code? Is it working properly with this LED status for TX?

My sys info:
USRP 2920s connected by MIMO cable
GNU Radio 3.7.10.1, UHD 3.11, Ubuntu 16.04

Best regards,

Bojun

foo_swig.py

Hi,

I followed the instructions and successfully installed gr-ieee802-11. But when I run wifi_loopback.grc, I got the following error:
File "/usr/local/lib/python2.7/dist-packages/foo/init.py", line 45, in
from foo_swig import *
ImportError: No module named foo_swig

I think there should have a "foo_swig.py" file in "/usr/local/lib/python2.7/dist-packages/foo/", but there isn't in my system. I also checked swig version by "swig -version", it shows:
SWIG Version 3.0.8

Compiled with g++ [x86_64-pc-linux-gnu]

Configured options: +pcre

what did I do wrong?

Thanks

libgnuradio-ieee802_11.so not found?

Hi, I've been setting up gr-ieee802-11 on a Linux Mint 17 installation with gnuradio 3.7.3.

Right now I'm just trying to build "/examples/wifi_phy_hier.grc" as detailed on the main Github page. However I get the following errors in Gnuradio-companion:

Error 0:
Block - header_formatter - Variable(variable):
Param - Value(value):
Value "ieee802_11.wifi_signal_field()" cannot be evaluated:

So after some googling I saw people suggesting to see the result of importing ieee802_11 in an interactive python session. This fails with the following import error:

import ieee802_11
Traceback (most recent call last):
File "", line 1, in
File "/opt/local/lib/python2.7/dist-packages/ieee802_11/init.py", line 37, in
from ieee802_11_swig import *
File "/opt/local/lib/python2.7/dist-packages/ieee802_11/ieee802_11_swig.py", line 28, in
_ieee802_11_swig = swig_import_helper()
File "/opt/local/lib/python2.7/dist-packages/ieee802_11/ieee802_11_swig.py", line 24, in swig_import_helper
_mod = imp.load_module('_ieee802_11_swig', fp, pathname, description)
ImportError: libgnuradio-ieee802_11.so: cannot open shared object file: No such file or directory

So I went searching for libgnuradio-ieee802_11.so and found it in /opt/local/lib.

What really gets me is I don't know why the line:

_mod = imp.load_module('_ieee802_11_swig', fp, pathname, description)

is even associated with libgnuradio-ieee802_11.so, since that isn't the file it's trying to load. I suppose the _ieee802_11_swig.so file must call it?

I also tried putting a copy of libgnuradio-ieee802_11.so in the /opt/local/lib/python2.7/dist-packages/ieee802_11/ folder to see if that would work with no luck.

I'm guessing there is something I did wrong in setting everything up, but I can't figure out what. Any ideas?

pass the message as argument to the python script or C code

Hi,

Thank you for your amazing work. I am in the middle of developing a protocol.
Are there anyway I can pass the message as argument to the python script or C code? I also want to control the output of the terminal.

About MAC parse

Hi,

I'm confused about one thing when I running the code. I found that there are lots of frames re too short to be parsed. And all of them are:

frame too short to parse (<20)
WIRESHARK: received new message
message length 10
WIRESHARK: d_msg_offset: 0 to_copy: 43 d_msg_len 43
WIRESHARK: output size: 32768 produced items: 43

Why the length of these frames is 10?

CSI in gr-ieee802-11

Hi,

Is there a way I can get the channel frequency response from the preamble similar to how the Intel 5300 calculates it ?

Is there a way I can modify the lib/equalizer//ls.cc or lib/equalizer/lms.cc to quickly extract the CSI for each successfully received frame ?

In other words: can I get the power and phase of each of the sub-carriers ?

Thanks!

Cannot use the wifi_tx on N210.

Hi,

I am trying to implement the 802-11 on to the N210, but wifi_tx.grc does not work with N210. Hope you can give me some suggestions.

I have tried many things to locate the problem, here is the summary of what is known:

1. If run wifi_tx and wifi_rx with two B200, everything works fine.
2. If run wifi_tx with B200 and wifi_rx with N210, everything works fine.
3. If run wifi_tx with N210 and wifi_rx with B200, nothing receives. The transmitting indicator LED A in the front panel is not on. But a very very very dim blinking for LED A can be seen if look very very close to it.
4. If for N210, run uhd_siggen_gui -a TX/RX -s 10M -f 1300M -x 3000 --sine, while for B2100 run uhd_fft -a type=usrp2, -f 1300M, -s 10M, everything works fine. LED A on N210 is bright on. Function test all right.

Could you give me some suggestion on this issue?
