Unclear if/how to attach Serial UART to hardware pins (non-USB, non-Bluetooth UART)

[cefn]

There is guidance at http://microbit-micropython.readthedocs.io/en/latest/uart.html indicating that the python library can access UART capabilities through the DAL which apply to hardware pins (note the tx and rx constructor arguments).

Am I right in thinking that the only UART exposed through Touchdevelop is the in-build UART-over-USB capability, and that accessing the Bluetooth UART service and use of a Hardware UART (through IO pins) is currently impossible?

If so, is there a chance that hardware or bluetooth UART will be exposed eventually through the serial library?

At this point, we are not planning any changes to the "built-in" libraries of the micro:bit. It leaves you with multiple options to implement your needs:

• write an extension library that contains the C++ glue to implement your custom behavior: https://github.com/Microsoft/microbit-touchdevelop/blob/master/EXTENSIONS.md
• file an issue at https://github.com/Microsoft/pxt-microbit where we would be able to handle this issue

Looks like pxt.io version already has support - using "serial redirect to". Thanks
