LoRa FHSS Receiving in STM32WL55JC (E5) module?

I want to work with Lora FHSS. Resources on this subject are limited.

 \STM32Cube_FW_WL_V1.3.0\Projects\NUCLEO-WL55JC\Applications\SubGHz_Phy\SubGHz_Phy_LrFhss. ;
I looked at the FHSS example you told me about. This example works in TX mode only. It only sends data using FHSS. I want to listen to this transmitted data with the same model STM32 Nucleo WLE5JC card. Is there an example of this? How can I configure the FHSS configuration to always listen?

This may be possible, but It is not tested.

Best Regards.

Hello @bozgan 

For now, there is not such an implementation. The only available example is the TX one that I've shared with you previously. 

Best Regards.

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

Let's say I ran the TX (transmission) based on your example. For listening (RX), what should I configure it according to? What criteria and factors should I pay attention to?

For now, this is not implemented on the current version of the stack. It will may be added on the future.

Best Regards.

AIUI, the LoRa part of STM32WL is based on Semtech IP ?

So, by looking at how Semtech do  this in their own drivers, one should be able to work out what to do it ... ?
