It retries several times (and gives us an interrupt for each retry) and then sends a final interrupt saying that it's given up. The definition of "failed to transmit" is "did not receive an ACK within a predefined timeframe". It has nothing to do with software or protocol retry. Lowering the rate would be a sensible experiment. > The nodes in my test are 5ft apart with 100% strength, 99% quality at > 54M on a clear channel.
