BLE disconnect

[Fiske]

I use below code to disconnect the BLE device from mobile phone. But it return err_code =7. Please comments.

            if(m_conn_handle!=BLE_CONN_HANDLE_INVALID)
                 {
                   LocalInitiateddDisconnect = true;
                    err_code = sd_ble_gap_disconnect(m_conn_handle, BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION);
                    APP_ERROR_CHECK(err_code);
                 }

What SDK and SoftDevice version are you using? What is the value of m_conn_handle?

[Fiske]

I am using S130 nRF5_SDK_12.0.0, Just don't know why the m_conn_handle value is Error (col 1): unknown or ambiguous symbol. m_conn_handle. I am using IAR.

[Fiske]

I am using the ble_uart_app example, and the m_conn_handle is the variable used in the app.

7 is NRF_ERROR_INVALID_PARAM, so it is probably m_conn_handle that is invalid. I'm not sure why, and it is a bit difficult with the amount of information you have given.

May be you have more than one declaration of m_conn_handle, one of them is global and second one is static?
