thanks. I'll ignore the reading if 127.

The RSSISAMPLE can hold values in the range of [0..127] in theory, but the stated accuracy of ±2 dB is only valid in the range -90 to -20, so you can consider a reading at -127 as non-valid.

I thought the "lowest" RSSI would be around 101 or so. How is it even detecting the signal if 127 really represents -127dBm? (I was hoping 127 or 0x7F was a flag to represent some error condition.)

I would also expect random numbers between 101 and 127 but nothing shows up in that range.

Hi,

I suspect it's caused by interference , reflections/multi-paths, etc
