Hi everyone,
I was using the HDLC block to receive AX25 packets of satellite signals.
I noticed that the block can sometimes produce packets that are
gibberish. This sounds very unlikely considering the CRC check in the
block. Has anyone experienced this problem?
Hi Moses,
The CRC is just a CRC-16, so getting false packets on a random input is
relatively likely. I've seen this plenty of times with gr-satellites.
Best,
Daniel.
