libxDot-dev-mbed5 15de249aa75f Radio Rx CRC error

[Mark Ruys]

The latest https://github.com/MultiTechSystems/libxDot-dev-mbed5 (db68b184a09f) does not work for me. Both with https://github.com/ARMmbed/mbed-os/tree/mbed-os-5.3.4 (269f58d75b75) and https://github.com/ARMmbed/mbed-os/tree/mbed-os-5.3.2, I get errors like

[DEBUG] ***** RxError ******

Reverting back to libxDot-dev-mbed5 15de249aa75f (and https://github.com/ARMmbed/mbed-os/tree/mbed-os-5.3.2), makes my node run again. Looks like the latest libxDot-dev-mbed5 has some issues?

Best, Mark

Mark,

Thanks for the debug info. The mbed-os-5.3.4 release introduced a bug that affected the xDot platform – essentially, setting a GPIO to 0 was impossible via the DigitalIn, DigitalOut, InterruptIn, etc APIs. The fix is in the mbed-os-5.4.1 release, but we don’t have any builds against that release yet.

We should have some new dev builds out relatively soon, but for now, the versions built against mbed-os-5.3.2 are your best bet.

Cheers,
Mike
