RE: manually disconnect paired smart device using interrupt.

Hello,

[quote user=""]I want to know how can I check the condition for any connected device?[/quote]

The SoftDevice will pass the BLE_GAP_EVT_CONNECTED and BLE_GAP_EVT_DISCONNECTED events to the ble_evt_handler function when the device is connected or disconnected. The default behavior of the ble_evt_handler is then to update the m_cur_conn_handle with the connection handle, or to reset it to BLE_CONN_HANDLE_INVALID if the event is disconnection.
So, your application logic can use this variable to determine whether it is currently in a connection or not.

[quote user=""]and how can I disconnect it manually using the button interupt?[/quote]

You may manually force a disconnect by calling the sd_ble_gap_disconnect function. Disconnection by button press is already implemented in the ble_app_cts_c example. You can see how this is implemented in the bsp_event_handler's BSP_EVENT_DISCONNECT event handling.

Best regards,
Karl
