No RX TTGO-BEAM with TTN Mapper

[arjanvanb (Arjan)]

Why are you expecting any RX at all?

You’ll only get RX for confirmed uplinks, if your application explicitly schedules a downlink, and for network commands like those for ADR. For mapping, you should not use confirmed uplinks, and for other usages downlinks (including confirmed uplinks) are limited to only 10 a day.

// ========= CODE changed to see if there RX action????
      //if (LMIC.dataLen) {  
        sprintf(s, "Received %i bytes of payload", LMIC.dataLen);
        Serial.println(s);
        sprintf(s, "RSSI %d SNR %.1d", LMIC.rssi, LMIC.snr);
        Serial.println(s);      
      //}     //// uncomment to test RX data

The original code already shows you the RX if there is any. If you want to change the logging, I’d simply only move sprintf(s, "Received %i bytes of payload", LMIC.dataLen); above the if (LMIC.dataLen). But I’d leave the if in place; you’re now logging RSSI and SNR values that are really not true.
