When I was using the device as peripheral, I was wondering when the Softdevice notified BLE_GAP_EVT_SEC_PARAMS_REQUEST and BLE_EVT_SEC_INFO_REQUEST:
1, when peripheral send security request, I will receive BLE_GAP_EVT_SEC_PARAMS_REQUEST?
2, when the central send pairing request, I will receive BLE_GAP_EVT_SEC_PARAMS_REQUEST?
3, there are other I did not expect the situation, will receive BLE_GAP_EVT_SEC_PARAMS_REQUEST it?
4, softdevice under what circumstances to send BLE_EVT_SEC_INFO_REQUEST?
