sd_ble_l2cap_cid_register(uint16_t cid) | |||
) |
Register a CID with L2CAP.
This registers a higher protocol layer with the L2CAP multiplexer, and is requried prior to all operations on the CID.
- Parameters:
-
[in] cid L2CAP CID.
- Returns:
- NRF_SUCCESS Successfully registered a CID with the L2CAP layer.
- NRF_ERROR_INVALID_PARAM Invalid parameter(s) supplied, CID must be above BLE_L2CAP_CID_DYN_BASE.
- BLE_ERROR_L2CAP_CID_IN_USE L2CAP CID already in use.
- NRF_ERROR_NO_MEM Not enough memory to complete operation.
SVCALL | ( | SD_BLE_L2CAP_TX | , |
uint32_t | , | ||
sd_ble_l2cap_tx(uint16_t conn_handle, ble_l2cap_header_t const *const p_header, uint8_t const *const p_data) | |||
) |
Transmit an L2CAP packet.
- Note:
- It is important to note that a call to this function will consume an application buffer, and will therefore generate a BLE_EVT_TX_COMPLETE event when the packet has been transmitted. Please see the documentation of sd_ble_tx_buffer_count_get for more details.
- Parameters:
-
[in] conn_handle Connection Handle. [in] p_header Pointer to a packet header containing length and CID. [in] p_data Pointer to the data to be transmitted.
- Returns:
- NRF_SUCCESS Successfully queued an L2CAP packet for transmission.
- NRF_ERROR_INVALID_ADDR Invalid pointer supplied.
- NRF_ERROR_INVALID_PARAM Invalid parameter(s) supplied, CIDs must be registered beforehand with sd_ble_l2cap_cid_register.
- NRF_ERROR_NOT_FOUND CID not found.
- NRF_ERROR_NO_MEM Not enough memory to complete operation.
- BLE_ERROR_NO_TX_BUFFERS Not enough application buffers available.
- NRF_ERROR_DATA_SIZE Invalid data size(s) supplied, see BLE_L2CAP_MTU_DEF.
SVCALL | ( | SD_BLE_L2CAP_CID_UNREGISTER | , |
uint32_t | , | ||
sd_ble_l2cap_cid_unregister(uint16_t cid) | |||
) |
Unregister a CID with L2CAP.
This unregisters a previously registerd higher protocol layer with the L2CAP multiplexer.
- Parameters:
-
[in] cid L2CAP CID.
- Returns:
- NRF_SUCCESS Successfully unregistered the CID.
- NRF_ERROR_INVALID_PARAM Invalid parameter(s) supplied.
- NRF_ERROR_NOT_FOUND CID not previously registered.
