I am having some issues with BLE. When I’ve try o use the example PROJECT 3 – ESP32 BLE Android aplication, this mensage appers:
Service C6FBDD3C-7123-4C9E-86AB-005F1A7EDA01, characteristic D769FACF-A4DA-47BA-9253-65359EE480FB are not published by the connected device.
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.
Can you share a screenshot of the error?
Can you enable the location in your smartphone before accessing the application?
That is the Screenshot’s link.
Esp32 BLE – Runtime Error
Bluetooth and location was activated, when I click on connect, show BLE’s list and when i clicked on the ESP’s adress the app crash and send this mensage.
Did you update to the latest BLE extension? The 2020 extension?
After updating, check if the Bluetooth blocks are still there. They can disappear during the updated.
If that’s the case, check this unit: https://rntlab.com/module-11/bluetooth-low-energy-ble-android-application-with-mit-app-inventor-2/
Check if some of the blocks are missing and add them, if needed.
