Did a bunch of testing, and a couple of local fixes. I will check them in if you want.
First the Serial.print(s) for the address rssi and lqi are missing DEC args.
Second I added some formatting if those are turned on
So I did some keyboard to keyboard testing, and this is what I get on one of them now.
The last line is messing 3 characters as well as the address info? I am going to poke into to this, as it came after I typed the 4th char, but something is going wrong that the addresses did not come out. I am suspecting this is not a ccx bug, but somewhere else. On the return path things slightly different, in that I get “, 3:” for the address??? and I see the same occasional failure with one char, followed by the rssi-lqi. I added the formatting to the address and rssi stuff so I can see the boundries while debugging.
I got a couple invalid rf data, but all without size. so I think it was this one i hit
stat=CCx.Read(CCx_RXFIFO,len);
// payloadLen should be total size - 3
if (*len != (size - 3)){
