#define SCK 18
#define MISO 19
#define MOSI 23
#define SS 5
#define RST 12
#define DIO0 13

In setup() I can start LORA

//SPI LoRa pins
SPI.begin(SCK, MISO, MOSI, SS);
//setup LoRa transceiver module
LoRa.setPins(SS, RST, DIO0);

if (!LoRa.begin(BAND)) {
delay(250) ;
Serial.println("Starting LoRa failed!");
while (1); // stop here


In loop(), as long as I don’t call LoRa.parsePacket() or LoRa.read(), the rest of the code runs fine. My conclusion is that after several hundred packets, something is going haywire in the library or the SPI driver. Anyone else see this? Are my SPI pin assignments a problem?

I tried to make this circuit with an esp8266 Wemos D1 Mini board with the declaration of these pins: https://randomnerdtutorials.com/esp8266-pinout-reference-gpios/

The ones corresponding to the SPI connection are connected correctly according to the Wemos D1 Mini pin diagram (SCLK, MISO, MOSI)
and

#define ss 15
#define rst 16
#define dio0 2

But both, in the transmitter and in the receiver through the serial port the only thing that is observed is “Noise” meaningless symbols
I checked the cable connections several times but everything was correct, I don’t understand what I could be doing wrong
When compiling and loading on the board it doesn’t give errors.

Any ideas?

Thanks

can we do it using Sx1262?

Hi.
Yes. The library is also compatible with the Arduino board.
Make sure you check the pinout for the Arduino: github.com/sandeepmistry/arduino-LoRa?tab=readme-ov-file#semtech-sx1276777879-wiring
