Issue about Starting LoRa failed!

[seyment]

Hi , I have 433M dragino lora shield with rf98 chip And I also use arduino mega. I used lora sender and lora receiver in both sides and both gave me the same problem Starting LoRa failed. My code is:

include

include

int counter = 0;

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

Serial.println("LoRa Sender");

if (!LoRa.begin(433E6)) { 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 have the same problem with Arduino Mega and LoRa RA-02 The same module and the same code work with Arduino UNO, but when I use the arduino MEGA it wont work LORA------------MEGA

MOSI------------51 SCK-------------52 MISO-----------50 NSS-------------10 RESET-----------9 DIO0-------------2

@Flavio-da-Brescia do you have a setPins call in your code for the Mega pins? LoRa.setPins(10, 9, 2)

[Flavio-da-Brescia]

Hello Torntrousers, yes I did try that too, but with no luck. With Arduino UNO that piece of code works, I can move the pins 10 and 9 to other pins and it works. I tried 3 different Arduino Mega and none of them will work... Thank you for the reply.

`/*

The transmitter code arduino for sending data packet lora radio module 433MHz ra02 lora

*/

include // arduino spi library

include // arduino libraries ra02 lora

int counter = 0;

void setup() {

LoRa.setPins(10, 9, 2);//NSS, NRESET, and DIO0 pins can be changed by using LoRa.setPins(ss, reset, dio0). Serial.begin(9600);

while (!Serial);

Serial.println("LoRa Sender"); //LoRa.setPins(10, 9, 2);

if (!LoRa.begin(433E6)) {

Serial.println("Starting LoRa failed!");

while (1);

}

LoRa.setSpreadingFactor(10);

LoRa.setSignalBandwidth(62.5E3);

LoRa.crc();

}

void loop() {

Serial.print("Sending packet: ");

Serial.println(counter);

// send packet

LoRa.beginPacket();

LoRa.print("Halo Like Circuit");

Serial.println(counter);

LoRa.endPacket();

counter++;

delay(2000);

}`

This is the code.

Im also using logic level shift, for UNO and for MEGA but no luck with the MEGA, only.

Ok I solved it. I simply forgot to connect the 5V of the logic converter. My bad. Thank you very much for all your support
