Hello,

I try to use the bluetooth Module with Appinventor BLE, but it doesn't works?
I try to use this module with NRFconnect and it works perfectly.
Here is my program BLE micropython: http://icnisnlycee.free.fr/images/SNT/o ... e_esp32.py
You can use program here. They works perfectly with NRFconnect, but doesn't work with appinventor.
https://github.com/micropython/micropyt ... /bluetooth

I used this library: https://docs.micropython.org/en/latest/ ... etooth.BLE
So there is somethong special in Appiventor extension here
http://iot.appinventor.mit.edu/#/blueto ... othleintro

Here the program in appiventor.

or there is something special in the module ubluetooth?
Thanks to help me please.

I saw someone (maybe you?) sent a PR showing an Appinventor example -- https://github.com/micropython/micropython/pull/6735 -- Does that give any hints?

I can't seem to load your code from that URL.

The ubluetooth module just provides a really low level GATT implementation. If your program is working from nRF Connect then it's suprising that it doesn't work from App inventor? Do they require that you use specific UUIDs or something?
