)

Formats and sends a GATT discover request.

Parameters
[in]conn_id: connection identifier.
[in]type: GATT discovery type.
[in]uuid: UUID of the attribute to search for.
[in]s_handle: Start handle.
[in]e_handle: Start handle.
Returns
wiced_bt_gatt_status_t
wiced_bt_gatt_status_t wiced_bt_util_send_gatt_read_by_handle ( uint16_t  conn_id,
uint16_t  handle 
)

Formats and sends a Read By Handle GATT request.

Parameters
[in]conn_id: connection identifier.
[in]handle: Attribute handle of the attribute to read.
Returns
wiced_bt_gatt_status_t

uint16_t  s_handle,
uint16_t  e_handle,
uint16_t  uuid 
)

Formats and sends a Read by Type GATT request.

Parameters
[in]conn_id: Connection handle
[in]s_handle: Start handle
[in]e_handle: End handle
[in]uuid: UUID of the attribute to read
Returns
wiced_bt_gatt_status_t

)

Copies a UUID.

Parameters
[out]p_dst: Destination UUID
[in]p_src: Source UUID
Returns
int 0 if success, -1 if error
