Hi,

I have two MKR WAN 1300 and I'm trying to communicate between them using LoRa. I'm using the sender code that is found in the Examples menu. The code is

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

int counter = 0;

void setup() {  
Serial.begin(9600);  
while (!Serial);

Serial.println("LoRa Sender");

if (!LoRa.begin(915E6)) {  
Serial.println("Starting LoRa failed!");  
while (1);  
}  
}

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

// send packet  
LoRa.beginPacket();  
LoRa.print("hello ");  
LoRa.print(counter);  
LoRa.endPacket();

counter++;

delay(5000);  
}

I just got the message

LoRa Sender  
Starting LoRa failed!

Any hint?

@victorg2310, well done solving this yourself.

Your topic has been moved to a more suitable location on the forum. _Installation and Troubleshooting_ is not for problems with your project 😉 See [About the Installation & Troubleshooting category](https://forum.arduino.cc/t/about-the-installation-troubleshooting-category/847458).

In future, please apply code tags to code that you post. It makes it easier to read, easier to copy and prevents the forum software from incorrect interpretation of the code.
