In my code I generate a node ‘frame counter’ and also the TTN backend has a frame counter.
Every time I transmit a frame the arduino increases the counter variable by one and transmit that value.
(for Cayenne I use ‘luminosity’)
The TTN backend , when receives this packet, also increases by one so these 2 values must be equal or we missed a frame.
For example, if it starts freezing like -5, there is a chance that the RN2483 (old model) wil stop transmitting and when then later the temperature rises, it will start working again… these 2 counters could point to that possible problem.
