Hi guys!
I am writing tou you, because I have a problem. I would like to create an app in App Inventor for controling my MaqueenPlus robot with micro:bit V2. I did create an app so far using BlocklyTalky for communication between app on my Android phone and micro:bit. I also tried to import a programm from MakeCode to micro:bit via USB. But I get 927 error, because unfortunately micro:bit V2 does not work with BlocklyTalky. I have read that it is compatible with V1 version so far. Could you guys please help me with it? Is there any possibility to connect micro:bit V2 to App Inventor app to control it with phone? Or maybe I can change software on microbit board from V2 to V1? Is there any possibility to do such an app? Please let me know and thank you for your help:)

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](https://forum.makecode.com/t/android-app-discord/7696/9) (@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!
