Gateway Pi showing received data in gibberish

[jaygould]

Hi all, I am sending data from a RFM98 (attached to an ESP32) to the other RFM98 attached to a Raspberry Pi 4b running LoRa gateway. The sending module is using arduino-lora.

The Pi is receiving the data but it's showing an incorrectly formatted string which looks like it's not been decoded correctly:

Not sure what the issue could be. Here's my sending code for reference:

#include <SPI.h>
#include <LoRa.h>

int counter = 0;

void setup() {
  Serial.begin(9600);
  while (!Serial);
  LoRa.setPins(4, 2, 15);
  LoRa.setSignalBandwidth(125E3);
  LoRa.setCodingRate4(7);
  LoRa.setSpreadingFactor(7);
  LoRa.enableCrc();

  if (!LoRa.begin(434E6)) {
    Serial.println("Starting LoRa failed!");
    while (1);
  }
}

void loop() {
  Serial.print("Sending packet: ");
  Serial.println(counter);

  LoRa.beginPacket();
  LoRa.print("$$hadie,");
  LoRa.print(counter);
  LoRa.print(",10:42:10,53.786244,-2.290401,27799.3,1:10\n");
  LoRa.endPacket();

  counter++;

  delay(4000);
}

I'm not familiar with that library. The HAB gateway doesn't do any decoding; it simply shows the string that the LoRa module has received. You could try different settings for LoRa; I suggest just setting mode 1 in the gateway and matching those settings at the transmitter. Other than that I have no suggestions. Dave

@daveake I've been banging my head against the wall since yesterday afternoon and all it took was to change the mode from 0 to 1. Thank you so much! 🙂

Excellent!
