Maybe not placed correctly in this post, but a related question:
There is a micro:bit Firmate firmware: GitHub - microbit-foundation/microbit-firmata: Firmata-like or Firmata-light protocol to communicate with the micro:bit, initially over Serial
Is it proper to try to use it to link micro:bit to SNAP! or SNAP4Arduino ?
I tried and was able to establish a link on first try. Could read some ports etc. But then it stopped working, saying "could not connect to board". No matter what I tried would not make it work.
This is NOT a crucial question needing an answer. If there is a known simple answer that's fine. Else don't spend cycles on it.
