Arduino Bluetooth and Inventor APP

Dear all,
I need your support in building an app with special features.
I recently approached MIT APP INVENTOR and I am not particularly experienced.
I have two temperature sensing systems with 2 ARDUINO NANO BLE boards (which has a bluetooth transmission system) each connected with a digital thermometer.

I need a very simple APP that, for each arduino board, makes me read just the following information via bluetooth connection:

  • DEVICE NAME
  • Temperature detected.

Example:
DEVICE 1
TEMP (DEVICE 1): 50 ° C

DEVICE 2
TEMP (DEVICE 2): 70 ° C

Is there any tutorial to figure out how to do such a thing?
Can anyone give me some advice on how to leave?

Thank you very much
Best Regards
Luca

Arduino Nano BLE usually works with the ArduinoBLE library. There are several examples in this Community.
