@bastibl Sir !
The default size of some buffers was too small to contain full-sized frames. I just pushed a fix. Let me know if it works for you.
Hi, sorry for getting back late.
it worked actually. Thanks a lot!
Hi,
I have downloaded and working with Gnuradio Version:3.8. I have modified the transceiver_OQPSK flowgraph and made it a transmitting radio for sending packets (attached image of flowgraph). It is working fine and we are able to send packets successfully from transmitting radio to another SDR or Openmote.
But I am facing an issue while sending packets with lengths of more than 57 bytes. By exploring code, I have found that code is always attaching 11 bytes in mac.cc & 4 bytes of the header along with the payload. Suppose if we have a payload of length 10 bytes, SDR will transmit a total of 25 bytes. We are able to validate this length on the receiving side. So coming back to the issue, when I am sending packets with more than 57 bytes altogether, the radio is giving an error and not transmitting anything.
Can you please guide me on how to overcome this issue? I am stuck for long and not able to move forward as I am new to gnuradio. Can you please suggest in which coding file should I look into resolving the issue?
any help will be much appreciated.
