Hello! I’m trying to change frequency band on my mdot with following code (based on latest MTDOT-BOX-EVB-Factory-Firmware):

    int32_t code;
    if ((code = dot->setFrequencyBand(mDot::FB_EU868)) != mDot::MDOT_OK) {
        std::string error = mDot::getReturnCodeString(code) + " - " + dot->getLastError();
        logError("CANNOT SET BAND: %s", error.c_str());
    }
    logTrace("BAND: %s", mDot::FrequencyBandStr(dot->getFrequencyBand()).c_str());

but this code still printing “[TRACE] BAND: US915” on debug uart.

After some exploration I found that setFrequencyBand() in libmDot-GCC_ARM.a from libmDot-mbed5 and libmDot-dev-mbed5 repos have following stub:

Disassembly of section .text._ZN4mDot16setFrequencyBandERKh:

00000000 <mDot::setFrequencyBand(unsigned char const&)>:
   0:   2000            movs    r0, #0
   2:   4770            bx      lr

Does that mean building with gcc isn’t really supported/tested?
