how the callback functions be called and the parameter transfered?

Hi,

The WICED SDK of 20735B1, I find functions for example, wiced_bt_gatt_status_t hello_sensor_gatts_callback( wiced_bt_gatt_evt_t event, wiced_bt_gatt_event_data_t *p_data),it was called by wiced_bt_gatt_register(hello_sensor_gatts_callback); But I haven't find where the value of event and p_data be set.

Thanks

Erxi

The event and data is set by the low level stack and customer can't get access to it.

Usually we use a timer to startup a callback. You can find that in the hello_sensor demo.
