Is there any way just use LoRa communication with B-L072Z-LRWAN1?

The Semtech radios inherently support LoRa comms in a point-to-(multi)point fashion. They have to layer on functionality to support LoRaWAN.

I'm not aware of any way to apply the "CubeMX" paradigm into Semtech libraries*, you really need to focus on pure HAL implementation, the subset that LRWAN uses, or a more underlying understanding of how the parts work, and how the libraries help or hinder development work.

*It's not so much a situation where things can't be done, but rather the costs of refactoring everything entirely is too high, and the delivered article being too large and slow, and drawing too much power.

Clicking a button in CubeMX is unlikely to ever deliver a solution or understanding of the problem space.

For Ping-Point : Understand the mechanics of what's happening, and the separation of the main loop from the transmission/reception. Add functionality that doesn't interfere with the timely operation of the radio, or the management of data in the main loop. Add depth of buffering when moving beyond the simplistic ping-pong interactions.

Thank you so much for your answer. So, are you advice to trying to change ping-pong example for my application?
