Just started working with the SAMR34 in a P2P setup. Reading from lab bench to about 55m (180ft) RSSI values of 0xc2, 0xa5 0xa0, 0x9c respectively. Not fully clear how to decode these values - but eyeballing the code it appears that,
*rssi = RSSI_HF_OFFSET + RADIO_RegisterRead(REG_LORA_PKTRSSIVALUE);
Actual signal power is –RssiPkt/2 (dBm)
but I'm not sure how to translate that value into actual dBm. 0xc2 == 192 (on same bench) where 0x9c = 158 and using -TTSPkt/2 one gets -96dBm and -78dBm which for close range (0xc2 or -96dBm and 180ft 0x9c or -78dBm) simply makes no sense. One should read stronger Signal values closer than far.
Makes no sense to me.
I tried 800ft and could not connect. ...have yet to try in-between. NEed to decipher RSSI's and perhaps read SNR.
Set to 915 (North American Freq (10) but running all else at default:
default data rate=5 (==Spreading Factor 7, SF7)
default BW = 125kHz
default TX Output Power = +1dBm with PA_Boost disabled
Any progress on your end?
