EmonTx crashing, any way to get logs?

I’ve been running extensive test but I’ve so far been unable to pin down the cause, other than it is happening during the process of transmitting the data.

I’ve also been testing a slightly modified version of the demo sketch (that comes bundled with the emonLibCM library) but using the “transmit-only” code lifted from the 3-phase sketch in place of the complete JeeLib - and that appears to be rock solid. As I write, it’s sent 173331 messages without resetting or locking up - just before the holiday it reached 525190 messages until I got fed up of waiting for it to fail, so I recommend you try that approach.

My tests with the power supply failed to make it lock up - every time, it recovered gracefully with only the message count and energy accumulators reset to zero as evidence.
