Issues Running SUBG2 UDP – No Communication Between Devices

lauris

Hello all,

The journey of trying to run 6LoWPAN on the S2LP continues. After resolving compilation issues (see: https://community.st.com/t5/stm32cubeide-mcus/not-compiling-subg2-generated-project-and-not-sure-if-working/td-p/803758), I can confirm that generating the project from the board caused problems, while generating from the MCU resolved most of them—except for a timer issue. Switching to the system timer (SysTick) resolved that as well, even though I initially wanted to keep it free and use a different timer.

However, after compiling and loading both the server and client projects onto their boards, the behavior remains the same: they seem to have no connectivity with each other. I also tried using the border router and a serial sniffer—none of them appear to be working. It's as if the devices stop responding within seconds. The serial sniffer doesn’t even register a button press event.

Does anyone have suggestions on where I should start looking or what I might be missing to get them working?

Thank you in advance,
Laurynas
