PACKET_SIZE = 128

def radio_sender():
    my_audio = audio.AudioFrame(duration=4000)
    while True:
        microphone.record_into(my_audio)
        audio_mv = memoryview(my_audio)
        for i in range(0, len(audio_mv), PACKET_SIZE):
            radio.send_bytes(audio_mv[i:i+PACKET_SIZE])

CODAL panic error 030 is a DEVICE_HEAP_ERROR. It could be an issue from the CODAL side, but it'd be good to try to confirm that first.

I saw this issue multiple times yesterday with that programme, but today I'm struggling to reproduce. I'll see if any of the modifications I might have done introduce this issue again, but if I can't find the right combination I'll close this issue.

I haven't been able to replicate this, so I'll close for now. I can always open it again if I do see it in the future and have an exact copy of the programme.
