  Hi I see the MDBT42Q Breakout uses the only UART for serial console.

  I'd like to use an RN2483A (I've a breakout board from tindie [1] on the way)

  Will it be possible in JS code to claim the UART for interfacing with this peripheral, and use the BLE interface for consoe/firmware/script upload.

  Some thoughts:
  a) I notice it checks the status of the MCU:RX <-- TX line.
  I assume the RN2483 isn't going to boot up with TX high (but that could be a gross presumption)

  b) Can the BLE radio be disabled in code? I would only need the radio on for config/update, it'd be nice to shut the radio down.

  c) What's the deep sleep current like on the MDBT42Q breakout compared to the Pico.
  I was going to use the pico but some off the PPI features look really interesting.

  Thanks.
