"No device responding" on LoRaReceive for WifiKit 32 V3 #83

Closed Frosty-STI closed 5 months ago

Frosty-STI commented 5 months ago

I have one WiFiKit 32 V3 flashed with the basic LoRa transmit code, and another flashed with the basic LoRa receive code. The transmitter side is printing this to the serial monitor:

You need to make sure the pin number allocations in the sketch are correctly changed to match your board.

On some ESP32 based boards you may need to change the SPI.begin(); command to identify the pin numbers for the SPI SCK, MISO and MOSI pins to this;

SPI.begin(SCK, MISO, MOSI);

Replacing SCK, MISO, MOSI with the pin numbers for you board.
