I am just wondering if somebody else experienced similar behaviour of a node. Depending on the environment, I had two cases of a node going into a reboot loop while transmitting. In one occasion it helped to tilt the wire helix antenna by about 45° to stop this happening. On the other occasion removing the node (in plastic box) from a corrugated sheet iron roof stopped the strange rebooting.
The node is a custom build PCB based on a ATmega328P and a RFM95 with a temperature and humidty sensor attached, a wire helix antenna and solar cells on top of the box.
I am not particularly asking how to fix this from happening as without showing schematics and the PCB nobody knows what I am doing.
It is more that I am wondering if this really is possible. It seems that during transmission some current is induced somewhere causing the Atmega to reset. Very strange…
