Hi @Maciek21,
You might be able to use the Bluetooth UART service instead or BlocklyTalky.
Here are a few things you may want to look in to:
- If you just want to use an App to interact with the Micro:bit, you can use existing apps. Here’s a discussion that includes details about using the Yahboom MBit app (Android and iOS) to control almost anything via a micro:bit: Android app/Discord - #9 by bsiever (@frank_schmidt has posted several videos in this forum showing a variety of uses).
- I found a few old discussions of using the UART service with App Inventor. I’m not sure how complete any of them are or if they still work, but:

- There are several others on the App Inventor forums too…
Good luck!
