Hello everyone, how are you? I
'm doing some communication tests between nRF52840 boards. I measure RSSI at different distances.
The problem is that in my tests, the RSSI got worse when I varied from 1 meter to 5 meters, 10 meters and 15 meters, all within expectations, however, when I went to distances of 20 meters and 25 meters, the signal started to improve.
I can't explain this signal improvement behavior when I increased the distance.
Does anyone have any suggestions?
I have attached two graphs.
I did the experiments with different PHY modes.
Thanks
