Seeeduino LoRaWan Uart

Hi there,

I looking to make a Seeeduino LoRaWan board communicate with a Raspi over Uart.
On the raspi side minicom is doing a great job and seems to be working fine (Rx and Tx linked).
However, once I try to do it on my Seeeduino it doesn’t work at all.

#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); // RX, TX

void setup() {
 // Open serial communications and wait for port to open:
 SerialUSB.begin(9600);
 while (!Serial) {
   ; // wait for serial port to connect. Needed for native USB port only
 }


 Serial.println("Goodnight moon!");

 // set the data rate for the SoftwareSerial port
 mySerial.begin(9600);
 mySerial.println("Hello, world?");
}
void loop() { // run over and over
if (mySerial.available()) {
  SerialUSB.println("test2");
}
if (Serial.available()) {
   mySerial.write("test1");
   }
}

Its not at all clear what you are trying to do, so to help us understand;

  1. Provide a link to the boards you are using.

  2. Provide a circuit diagram of how you have this wired up.
