wiced_bt_gatt_buffer_transmitted_t Struct Reference

Description

Structure to return the application buffer and application buffer context given to the stack in various APIs The application is expected to use this event to free allocated memory used for sending client requests or responding to client requests.

On client this is the buffer sent to the stack in

  Note

  Typically the application context is expected to be a function/hint (used by the application) to allow it to free/deallocate the memory passed to the stack when writing data to the stack. For e.g, when issueing wiced_bt_gatt_client_send_write, the app can allocate p_app_write_buffer and set the p_app_ctxt to the appropriate free function. This memory allocated for this transaction has to be freed when returned by the stack in the GATT_APP_BUFFER_TRANSMITTED_EVT. The process is made simple since in this case as p_app_data is the application p_app_write_buffer and p_app_ctxt is the application free function/hint

  GATT_APP_BUFFER_TRANSMITTED_EVT is expected to be used only to free app memory as described. The next transaction should be attempted on the respective GATT_OPERATION_CPLT_EVT
