I am doing some experiments where I send use 2 nrf52840 DKs in a closed setup. Packets are advertised over channel 37, 38, 39 and I am looking at the RSSI values and some other stuff.
Now my question: I would expect to receive the packets mostly in the same order: 37, 38, 39. However, sometimes it can happen that I get the values of one channel two or more times. (e.g. 37 (rssi..), 38 (rssi..), 39 (rssi..), 37, 38, 38, 39... So two times a packet from channel 38. Is it possible to tell if it was a retransmission or just simply a multipath signal?
My setup is a harsh environment, where there are a lot of reflections, and the distance is rather small (within 1.5 m). So I definitely would expect that some of the received packets are such multipath reflections.
