Hello
Is it possible to connect the microbit to the computer with bluetooth or Wifi and then use the computer keyboard to control the microbit?
I mean, using the computer keyboard we have a big range of possible comands to send to the microbit.
If yes, can anyone explain how to do it please?
I searched only for any tutorial about this but found nothing about using the computer keyboard to control the microbit...
Thanks!

Re: Connect Microbit to Computer with Bluetooth or Wifi
Hi,
Microsoft MakeCode supports Bluetooth BLE on the micro:bit. MicroPython does not.
See: https://microbit-micropython.readthedoc ... cs/ble.htm
If I want to control a micro:bit from my laptop, I use a second micro:bit connected to the laptop.
What follows works with both V1 and V2 micro:bits.
On the laptop run this program (Linux laptop with Python installed):
On the micro:bit connected to the laptop:
And on the microbit (with battery) you want to control remote:
Now if you type something after the prompt on the laptop followed by Enter, the
text scrolls on both micro:bits. Use the messages to get commands from your laptop
to the remote micro:bit.
This is actually a project we did at our local CoderDojo sessions.
