Function Documentation#

cs_ras_convert_data#

sl_status_t cs_ras_convert_data (cs_ras_subevent_header_t * ras_subevent_header, cs_ras_ranging_header_t * ras_header, const sl_bt_msg_t * cs_res, bool continue_evt)

Parameters

Type	Direction	Argument Name	Description
cs_ras_subevent_header_t *	[in]	ras_subevent_header	CS result data.
cs_ras_ranging_header_t *	[out]	ras_header	The connection handle.

bool	[in]	continue_evt	True, if this is a continuation event.

Convert from event data to RAS format as specified by the SIG standard.

Returns

status of the operation.
