It's register 05 for the RSSI.Btw, after almost a month I got an email saying that my RFM22 were shipped...
I had asked to include one of these cheap 2.4Ghz... but got no reply. :SWe'll I'm going to start assembling the boards as yesterday I got the solder paste and I expect the RFM's to arrive during next week.
That's a long time to wait! I have been flying my plane with the RFM22, it's working great so far.
Register 05 is write-only, it's "RSSI Threshold for CD detect". You can't read the RSSI value from it.
