Hi,
I am having some issues with BLE. When I’ve try o use the example PROJECT 3 – ESP32 BLE Android aplication, this mensage appers:
“Runtime Error
Service C6FBDD3C-7123-4C9E-86AB-005F1A7EDA01, characteristic D769FACF-A4DA-47BA-9253-65359EE480FB are not published by the connected device. 

End Application”
Do you have any idea about how could I solve this problem? 
Note: I already downloaded the new BLE version for App Inventor and substituted the old one.
