esp8266ndn's Issues

esp8266ndn installation issues

I am very interested to run the NDN on ESP32 and have seen that you already have implemented it.

After cloning the "NDNph" and the esp8266ndn examples form GIT flowing the steps here "https://github.com/yoursunny/esp8266ndn", I am now trying to run your code but I have some issues regarding the installation the esp8266ndn on my board. I would like to use the ESP32 Dev board.

The project example "PingClient" from yoursunny/esp8266ndn/\examples does not find the library with the name "esp8266ndn". I am getting the error "PingClient:8:24: fatal error:
esp8266ndn.h: No such file or directory".

Can you please help my with this error? Is there something which I should do before I start the installation?

Best wishes

Is it possible to use esp8266ndn as forwarder

Hello,
I was wondering if it's possible that this esp8266ndn library also forwards Interest / Data packets?
Take a look at my setup:
.

The first one is my current setup. All sensors are connected to a NFD instance in a star topology. This way all sensors can communicate with each other.
But is it possible the get the second setup, where only one sensor is connected to the NFD instance and the other sensors use (in this case Sensor 3) as a gateway?
If that's possible how would I configure my ESP32 firmware (using esp8266ndn) to do so?

Signature type and length are missing in interest name

Hello, there is a possible bug that the signed interests generated by the esp8266ndn library have an incorrect TLV encoding.

Two of the strange things about the TLV I found were this:

1. There is no 0x17 (signature value type) or 0x22 (expected signature value length, 32 bytes) in the signed interest TLV generated by the esp8266ndn library
2. The generic name component under which the signature value should be nested has an incorrect
   length; the length indicates 32 bytes, but there are 36 bytes in that generic name component.

The exact error output from PyNDN2 was this:

Traceback (most recent call last):
  File "test_sign_verify_interest_hmac.py", line 114, in <module>
    main()
  File "test_sign_verify_interest_hmac.py", line 93, in main
    if KeyChain.verifyInterestWithHmacWithSha256(interest, key):
  File "build/bdist.linux-armv7l/egg/pyndn/security/key_chain.py", line 1364, in verifyInterestWithHmacWithSha256
  File "build/bdist.linux-armv7l/egg/pyndn/encoding/tlv_0_2_wire_format.py", line 505, in decodeSignatureInfoAndValue
RuntimeError: Did not get the expected TLV type

Below I have pasted an interest TLV that verifies correctly with PyNDN2, and the interest TLV generated by the esp8266ndn library that failed to verify because of a TLV unexpected type error.

This interest verifies correctly with PyNDN2:

TlvInterest = Blob(bytearray([

Issues getting the example to compile using the Arduino IDE

Hello,

I am really interested in your NDN libraries and tried to get one of your examples to work on my ESP-WROOM-32 but unfortunately I get compiler errors.
I have done the following things (on my Windows machine):

• Installed the latest version of the Arduino IDE
• Installed the ESP32 boards in the IDE
• Installed both the latest master of this library as well as NDNph to <User>/Documents/Arduino/libraries
• Restartet the IDE

But when I now run this simple program

#include <esp8266ndn.h>

void setup() {
}

void loop() {
}

I get the following exception
