NUCLEO-WL55JC2 RF example – simple Tx/Rx reference needed

[Xagon]

Hello,

Board: NUCLEO-WL55JC2 (2 boards)
MCU: STM32WL55JC
IDE: STM32CubeIDE
Programming: Bare-metal C or Cube IDE(C/C++)

Goal:
I want a minimal RF example using two NUCLEO-WL55JC2 boards where one board transmits a simple message and the other receives it and for example toggles an LED .

I searched on ST website and GitHub, but most available examples are full LoRaWAN stacks. I could not find a simple RF Tx/Rx reference similar to an LED blink example.

I have not written RF code yet and am looking for an official ST reference to start from.Suggest any website reference or youtube videos where i can understand it clearly.

Questions:
1. Is there an official ST RF Tx/Rx example for NUCLEO-WL55JC2?
2. Any recommended CubeWL example or GitHub repository?
3. Which example is best for learning basic RF communication?

4. Should i need to use the RF like NRF24L01 Transcever or does it supports?

Thanks in advance.

Look for the "Ping-Pong" example: that's a simple peer-to-peer link using only LoRa modulation - no LoRaWAN network.

PS:

I think the LoRa Ping-Pong example is in I-CUBE-LRWAN; 

There's also one for the Sub-Ghz PHY STM32CubeWL:
