LoRa Node to Node

Summary​

On the premise of no hardware problem, LoRa nodes can communicate with each other node-to-node. The key to success node-to-node communication need make sure the following 7 points the same:

  1. The same sending and listening frequency: LoRa.setFrequency(frequency);
  2. The same bandwidth: LoRa.setSignalBandwidth(signalBandwidth);
  3. The same coding rate: LoRa.setCodingRate4(codingRateDenominator);
  4. The same preamble length: LoRa.setPreambleLength(preambleLength);
  5. The same sync word: LoRa.setSyncWord(syncWord);
  6. The status of LORA_IQ_INVERSION is the same;
  7. the same SPREADING FACTOR;
