BLE goes from LE Only to CLASSIC and LE

Postby Rafael Albarello » Wed Feb 13, 2019 6:09 pm

I have two Heltec LoRa ESP32, and i'm trying to set up and APP to read values from them. However, after 2 days testing, one of the boards stopped working with BLE, and the "nRF Connect" app says the connection is "CLASSIC and LE", when it should be "LE Only".

I've tryied using the exact same code of gatt_server (https://github.com/espressif/esp-idf/tr ... att_server). With one board, it works properly, while with the other, it shows the "CLASSIC and LE", and my app fails to connect with it. I've tryied make clean, make erase_flash, but nothing seems to work.

Is it possible that the BLE module in the board broke? If yes, what can I do to avoid getting the other board broken as well?

Thanks.
