Currently we provide the sensor API's as one library extension sample. In the header file ```lib/app-libs/extension/sensor/sensor.h```, the API set is defined as below:
``` C
sensor_t sensor_open(const char* name, int index,
void(*on_sensor_event)(sensor_t, attr_container_t *, void *),
void *user_data);
void(*on_sensor_event)(sensor_t, attr_container_t *, void *),
void *user_data);
bool sensor_config(sensor_t sensor, int interval, int bit_cfg, int delay);
bool sensor_config_with_attr_container(sensor_t sensor, attr_container_t *cfg);
bool sensor_close(sensor_t sensor);
```
We provide the connection API's as another sample. In the header file `lib/app-libs/extension/connection/connection.h.`, the API set is defined as below:
``` C
/* Connection event type */
typedef enum {
/* Data is received */
CONN_EVENT_TYPE_DATA = 1,
/* Connection is disconnected */
CONN_EVENT_TYPE_DISCONNECT
} conn_event_type_t;
typedef void (*on_connection_event_f)(connection_t *conn,
conn_event_type_t type,
const char *data,
uint32 len,
void *user_data);
connection_t *api_open_connection(const char *name,
attr_container_t *args,
on_connection_event_f on_event,
void *user_data);
void api_close_connection(connection_t *conn);
int api_send_on_connection(connection_t *conn, const char *data, uint32 len);
bool api_config_connection(connection_t *conn, attr_container_t *cfg);
```
