Not recognized PICO LORA SX1262 + RPI PICO 2W

[multivac2x]

I am trying to setup a small node with PICO LORA SX1262 + RPI PICO 2W using the LORAWAN_STARTER example. Currently I was able to setup the Arduino IDE in Windows to support the compilation of RadioLib.

The LORAWAN is the following https://www.waveshare.com/wiki/Pico-LoRa-SX1262

I checked in this forum and even trying to use some solutions proposed I was not able to setup the 1262 , this because the Pico Lora 1262 is not recognized. What is it my mistake?

[... same code as default...]

From the debug output, it is clear that no data is being sent on the bus. Since you are not using the default SPI bus, you have to initialize it with SPI1.begin(), or whatever is appropriate on the RPi Pico. This has to be done before the radio.begin() call, as shown in the Custom SPI wiki page, as well as in the discussion you have linked from the code.
