◆ prf_find_handle_by_idx()

uint16_t prf_find_handle_by_idx ( uint8_t  idx,
uint16_t  start_hdl,
uint8_t *  p_char_mask 
)

Find the attribute handle by index.

Parameters
[in]idxThe attribute index in the service's attribute table.
[in]start_hdlThe start handle value in the database.
[in]p_char_maskPointer to the mask of characteristics which are added into BLE Stack database from the service's attribute table.
Returns
The handle of the attribute with the index in BLE Stack database.

◆ prf_find_idx_by_handle()

uint8_t prf_find_idx_by_handle ( uint16_t  handle,
uint16_t  start_hdl,
uint8_t  char_nb,
uint8_t *  p_char_mask 
)

Find the attribute index by handle.

Parameters
[in]handleThe handle of a characteristic in BLE Stack database.
[in]start_hdlThe start handle of a service in BLE Stack database.
[in]char_nbThe number of the characteristics in a service's attribute table.
[in]p_char_maskPointer to the mask of characteristics which are added into BLE Stack database from the service's attribute table.
Returns
The handle's index in the service's attribute table.
