Control handle values

Hi,

Another question that I have about the GATT DB is whether or not the handle values can be assigned manually. For device cloning purposes, this could be advantageous. bleno does not support this, but I suspect that PyBT would.

Thanks, and have a great day.

Connection Handle never modified ?

Hi,
It seems that the connection handle is never modified :

    def raw_att(self, data):
        self.s.send(HCI_Hdr()/HCI_ACL_Hdr(handle=64)/L2CAP_Hdr(cid=4)/data)

Is it normal ? I have to change this piece of code to make it works.

Facing Problem when Installing PyBT

Hi All,
When I'm Installing getting below errors. I'm forking the code from master branch and I Installed scapy as suggested.

Traceback (most recent call last):
File "setup.py", line 1, in
from setuptools import setup
ImportError: No module named setuptools

So,please provide solution to this problem.

Thanks...

GATT DB Server Error

Hi,

I don't think this is a problem with PyBT. I think it is a problem in my use of PyBT.

I am attempting to create a peripheral with a rudimentary GATT DB. You can see the code here: https://github.com/jennj/BLE-Scripts/tree/master/scripts-peripheral . The example advertises; I can see the advertised data in the nRF Connect app with no problems. When I attempt to connect, though, the connection fails with an error 0x85. According to Nordic this means a problem with the GATT server configuration. The server data matches that what I receive when I perform a gattlib read-by-handle (you can see the output of read-by-handle at the bottom of the file referenced above. This likely means that I am missing something. What am I missing? I would be grateful for a hint.

Ubuntu 16.04
bluez 5.37
scapy -> the one you linked in the PyBT page
PyBT -> the latest version

Latest versions of pycrypto and gevent are installed (what is standardly available with Ubuntu).

Thank you, and kind regards,
JennJ

Error: cannot convert argument to integer

Hi,
I have installed scapy 2.3.3 and was able to run gattclient.py. However, when I typed connect BD_ADDR random in the interactive console, I got the error:
Cannot convert argumetn to integer
The error occurred in scapy/fileds.py when calling s+struct.pack(self.fmt, self.i2m(pkt, val)) function.
Any idea on this?
Thanks : )

Execute the gattclient.py

Hi,
I have installed PyBT. However, I could not figure out what is the usage of gattclient.py? Any help would be appreciated!
