@rvandam You can get the timestamp of the last received LoRa packet with lora.stats() (docs), if that helps.

Hi @pierrot10 The internal ADC has very poor performance. The non linearity is poor and it has a high noise floor. I think someone earlier suggested using an external ADC and I think that is very good advice.

@river Thanks I didn't even thought about IC pin headers, good idea, will try them for sure. You're welcome for the board, looks like IoT world is still small ;-)
