Issues with BLE and Microbit

I followed the Microbit x App Inventor tutorial by @Ghica and used the BLE extension (edu.mit.appinventor.ble-20230223-beta.aix), along with other extensions, including both the old and new versions of the micro:bit extension. However, I'm still encountering issues.

I followed all the steps and successfully connected via Bluetooth, but when I try to send a text to the micro:bit, I receive an error stating that Bluetooth was not initialized correctly—despite the micro:bit showing as 'connected'.

Has anyone encountered this issue before or know how to fix it?

Here are the extensions I used:

  • Microbit extension (also tried other versions):
    com.bbc.microbit.profile.aix
  • Project file:
    blank3.aia

You should at least use the latest BLE extension that can be found here

You also didn't post your project file.
