Expect that you'll need to review and modify the software stack to address the specifics of your implementation, and how the RF signals are gated via the RF switch/mux in-front of the antenna, and how many "ways" that can go, the number of pins involved, and the HIGH/LOW states with respect to the mode/mixing you want to occur. Perhaps start by looking at the Data Sheet for the RF part first, and how it's wired in your implementation.
Think of this from a HW perspective, not a SW Engineering one.
The Murata module implementation has THREE paths, Receive, Output Highest Power, Output Normal Power, other designs/implementations have a Receive OR Transmit, but the MUX can gate both channels on together, which you don't want
no, i have to modify the STM32 CUBE LRWAN because use TWO GPIOS to control the direction, transmit and receive data, am i right ?
I have to modify it to make this direction control, using only on GPIO, right ?
No, probably not right, look at the schematics/block diagrams. Pretty sure there's THREE on the B-L072Z-LRWAN1 (DISCO), but you're being super vague about YOUR design.
Which board are you using? Something of your own creation? The Semtech Shields?
If YOUR design has one or two pins you'll need to walk the software and do a clean port for your implementation that fully takes into account the modes of operation, and transitions, and timing/sequencing properly. Not simply an affirmation by third-parties that it's "right" or completely handled.
