Project description:
"I have an STM32-based ExpressLRS build on my bench that compiles and flashes fine, yet refuses to play nicely with the controller. The stumbling block is the software side: pin maps, USART assignments, and protocol options that need to match the RF gear. I’d like an experienced ELRS developer who already knows the STM32CubeIDE / PlatformIO workflow to jump in, review my current repo, and pinpoint what I’m overlooking.

Here’s what I need from you:

• Screen-share to help troubleshoot on our system and hardware.
• Corrected configs or a custom target file that lets the MCU link, bind, and pass telemetry with the specified RX/TX pair.
• A brief rundown of the changes so I can reproduce them next time.

I can provide the existing source, compile logs, and real-time test feedback as we go. Once your tweaks let the board reliably bind and exchange packets with my receivers and transmitters, I’ll consider the job done.

Board is based STM32L432KB based. Our RX works fine, the TX flashes, and seems to have a heartbeat, but it is not possible to activate the lua script on the controller or bind between the TX and RX. We are reasonable sure the hardware is correct but are able to make changes as needed. Willing to pay project price plus a bonus for swift work." (client-provided description)
