Some of the ble_services does a gatt_read being a client. There are few examples that use this API to read the data from the peer(server).

Thank you for your support. I will read the documentation and try to implement it in the code. Meanwhile do you have a example where the sd_ble_gattc_read() is used and already implemented?

Please read the API documention for sd_ble_gattc_read. m_data_value in your case should be the handle to the characteristic you want to read which should be obtained from the service discovery procedure.
