App Inventor unknown Run Time error

I am trying to connect app inventor and micro:bit. This error keep on appearing but I do not understand what is it about and where to locate the error to be corrected.

Anyone have any advice?

What companion are you using? Android or iOS?


Did you set the BluetoothDevice property of the Microbit_Accelerometer1 component to the BluetoothLE1? The error in question is usually caused by not having established the relationship between the component and the BLE providing the connection to the device.


android 10

Did I missed anything? i suppose I should have done in coding, Pls kindly tell me if I need other blocks,
