Frame format encoding of the BLE_EVT_TX_COMPLETE packet.
Event ID = 0x01 for BLE_EVT_TX_COMPLETE
All BLE events, ble_evt_t, are encoded with the header ble_evt_hdr_t first, containing only the Event ID followed by the event. The Event Length will not be encoded, because the size of the event could differ depending on the decoder architecture.
The event contains a connection handle. For the BLE TX complete, the ble_evt_tx_complete_t is encoded after the connection handle, as seen in Figure 1.
The order of the encoding is:
Length | Parameter | Value |
---|---|---|
2 bytes | Connection Handle | See ble_common_evt_t::conn_handle |
1 byte | Count | See ble_evt_tx_complete_t |
Frame format encoding of the BLE_EVT_USER_MEM_REQUEST packet.
Event ID = 0x02 for BLE_EVT_USER_MEM_REQUEST
All BLE events, ble_evt_t, are encoded with the header ble_evt_hdr_t first, containing only the Event ID followed by the event. The Event Length will not be encoded, because the size of the event could differ depending on the decoder architecture.
The event contains a connection handle. For the BLE USER MEM request, the ble_evt_user_mem_request_t is encoded after the connection handle, as seen in Figure 1.
The order of the encoding is:
Length | Parameter | Value |
---|---|---|
2 bytes | Connection Handle | See ble_common_evt_t::conn_handle |
1 byte | Type | User Memory Type, see ble_evt_user_mem_request_t::type |
Frame format encoding of the BLE_EVT_USER_MEM_RELEASE packet.
Event ID = 0x03 for BLE_EVT_USER_MEM_RELEASE
All BLE events, ble_evt_t, are encoded with the header ble_evt_hdr_t first, containing only the Event ID followed by the event. The Event Length will not be encoded, because the size of the event could differ depending on the decoder architecture.
The event contains a connection handle. For the BLE USER MEM release, the ble_evt_user_mem_release_t is encoded after the connection handle, as seen in Figure 1.
The order of the encoding is:
Length | Parameter | Value |
---|---|---|
2 bytes | Connection Handle | See ble_common_evt_t::conn_handle |
1 byte | Type | User Memory Type, see ble_evt_user_mem_release_t::type |
2 bytes | Length | User Memory Block Length, see ble_user_mem_block_t::len |
1 byte | Memory Block Present | 0x00 - not present, 0x01 - present |
