ESP-IDF Simple BLE Client

[_marco95_]

Hi,
I'm compiling and running the example code for the BLE GATT CLIENT, contained id

Code: Select all

C:\Espressif\frameworks\esp-idf-v5.1\examples\bluetooth\bluedroid\ble\gatt_client

but I cannot find my BLE device server that implements BLE protocol.
I can succesfully get connected to that server with my smartphone using "BLE Scanner" or even "nRF Connect" but the example provided does not find the server.

What would be the possible cause? And how to solve that? I think there are no any particular filters set in software. Could it be that the protocol of the server does not match with the one supported by esp32?

Thanks,
Marco.
