BLE Common Events

General Description

The BLE Stack generates events to notify the application on various status alerts concerning the stack.

These can be generic stack events or can be specific to GAP, GATT or L2CAP layers. The service specific events are handled separately in BLE Service-Specific Events.

cy_en_ble_event_t

enum cy_en_ble_event_t

BLE stack events.

Enumerator
CY_BLE_EVT_INVALID	This event is triggered by the BLE stack when the BLE Stack is in a bad state. Restarting the BLE Stack is the only way to get out of this state
CY_BLE_EVT_STACK_ON	This event is received when the BLE stack is initialized and turned ON by invoking the Cy_BLE_StackInit() function.
CY_BLE_EVT_TIMEOUT	This event is received when there is a timeout and the application must handle the event. Event parameter is of type 'cy_stc_ble_timeout_param_t'. If reasonCode is 'CY_BLE_GATT_RSP_TO', then look for connHandle. If reasonCode is 'CY_BLE_GENERIC_APP_TO', then look for timerHandle. For all other cases connHandle or timerHandle is ignored
CY_BLE_EVT_STACK_BUSY_STATUS	This event is triggered by BLE Stack to indicate if the BLE stack is busy or not. The Event Parameter corresponding to this event will indicate the state of BLE stack's internal protocol buffers for the application to safely initiate data transactions (GATT, GAP Security, and L2CAP transactions) with the peer BLE device. Event parameter is of type cy_stc_ble_l2cap_state_info_t. cy_stc_ble_l2cap_state_info_t contains flowState and Bd handle as parameters flowState indicates the following state: CY_BLE_STACK_STATE_BUSY (0x01) = CY_BLE_STACK_STATE_BUSY indicates to the application that the BLE Stack's internal buffers are about to be filled, and the remaining buffers are required to respond to the peer BLE device. After this event, the application shall not initiate GATT, GAP Security, or L2CAP data transactions. However, the application shall respond to peer initiated transactions to prevent BLE protocol timeouts. Application initiated data transactions can be resumed after the CY_BLE_EVT_STACK_BUSY_STATUS event with parameter 'CY_BLE_STACK_STATE_FREE' is received. CY_BLE_STACK_STATE_FREE (0x00) = CY_BLE_STACK_STATE_FREE indicates to the application that pending transactions are completed and sufficient buffers are available to process application-initiated transactions. The 'CY_BLE_EVT_STACK_BUSY_STATUS' event with 'CY_BLE_STACK_STATE_FREE' indicates to the application whether the BLE Stack's internal buffer state has transitioned from 'CY_BLE_STACK_STATE_BUSY' to 'CY_BLE_STACK_STATE_FREE'. Bd handle indicates connection. To increase the BLE Stack's default queue depth(CY_BLE_L2CAP_STACK_Q_DEPTH_PER_CONN) and achieve better throughput for the attribute MTU greater than 32, use the AddQdepthPerConn parameter in the 'Expression View' of the Advanced tab in the BLE component GUI. To Access the 'Expression View', right click on the 'Advanced' tab in th BLE Component GUI and select the 'Show Expression View' option.
CY_BLE_EVT_MEMORY_REQUEST	This event is received when the BLE Stack wants the application to provide memory to process a remote request. The event parameter is of type cy_stc_ble_memory_request_t. This event is automatically handled by the BLE Component for the CY_BLE_PREPARED_WRITE_REQUEST request. The BLE Component allocates sufficient memory for the long write request with the assumption that attribute MTU size is negotiated to the minimum possible value. The application could use dynamic memory allocation to save static RAM memory consumption. To enable this event for the application level, set the EnableExternalPrepWriteBuff parameter in the Expression view of the Advanced tab to be true.
CY_BLE_EVT_PENDING_FLASH_WRITE	This event is used to inform the application that a Flash write is pending. This event is generated by the BLE Stack whenever its internal data structures are modified and require back up.
CY_BLE_EVT_FLASH_CORRUPT	This event is used to inform the application that persistent data stored in Flash memory is corrupted.
CY_BLE_EVT_HARDWARE_ERROR	This event indicates that some internal hardware error has occurred. Reset of the hardware may be required. Event parameter returned with this event is of (uint8 *) type. The possible error codes for this event are defined in cy_ble_stack_host_error.h file.
