transceiver_OQPSK fails to transmit #65

Closed dfa327 closed 1 year ago

dfa327 commented 1 year ago

Hello, Love the tools you've made and thank you for doing so :) I'm having an issue with the transceiver_OQPSK.grc. I get a seg fault when I uncomment the Message Strobe in GNURADIO 3.10.1. I've narrowed it down a bit and if I send more than 8 bytes directly in to the IEEE802.15.4 OQPSK PHY block it throws the seg fault. Can you please help me? I've adjusted the shared memory to 8g and ran the volk profiler. The RX works perfectly for 46 bytes packets by the way :) So this is purely a Tx issue. Please share any troubleshooting tips.

Thank you again:)

GNU Radio 3.10 had a bug in one block that is used in the transmitter. You probably need a more recent version. See https://github.com/bastibl/gr-ieee802-15-4/pull/58#issuecomment-1299591824

Whoa! You are fast!!!!!! I think I found what you're talking about. It isn't fixed in 3.10.1 nor 3.10.4, but it is in main branch :(

Thanks again for all your hard work!!! Very much appreciated!
