How to check connection is being established?

Question

Hi, 
 We want to have same key for handling accept for LESC pairing and sleep mode if BLE is in advertising. 
 The implementation is based on ble_app_hrs_pca10040_s132. 
 SDK: nRF5_SDK_16.0.0 
 How do I check the connection is being established? 
 =>To ignore the keypress in case BSP_EVENT_SLEEP. 
 void bsp_event_handler(bsp_event_t event)
{
 switch (event)
 {
 case BSP_EVENT_SLEEP:
 if (connection is being established or connected )
 {
 //do nothing 
 }
 else
 {
 sleep_mode_enter();
 }
 break;
 case BSP_EVENT_KEY_0:
 NRF_LOG_INFO("BSP_EVENT_KEY_0 m_conn_handle %d", m_conn_handle);
 if ((m_conn_handle != BLE_CONN_HANDLE_INVALID)
 && (fg_accept == false)
 ){
 NRF_LOG_INFO("press BSP_EVENT_KEY_0 accept");
 
 on_num_comp_button_press(true);
 fg_accept = true;
 
 }
 break;
 ...
 }
 }
} 
 Thanks. Vick

Hi, 
 Two events will be generated during a pairing procedure. The first is the BLE_GAP_EVT_SEC_REQUEST which is generated at a start of the pairing procedure. A BLE_GAP_EVT_AUTH_STATUS event will be generated at the end of the paring sequence. You can use these two events to set flags which would indicate what state the pairing procedure is at. 
 See the message sequence diagrams for the pairing procedures . 
 hope that helps
