Returns

WICED_SUCCESS : on success.

WICED_ERROR : if an error occurred with any step

wiced_result_t wiced_audio_timer_get_frame_sync

(

uint32_t

timeout_msecs

		uint32_t *	audio_time_secs,
		uint32_t *	audio_time_nanosecs
	)

Read audio timer value in seconds and nanoseconds; a valid audio sample rate needs to be provided

Parameters

[out]	ticks_per_sec	: Returned audio timer resolution

Returns

WICED_SUCCESS : on success.

WICED_ERROR : if an error occurred with any step

wiced_result_t wiced_audio_timer_get_time	(	uint32_t *	time_hi,
		uint32_t *	time_lo

Retrieve the origin timestamp in the last sync message, correct for the intervening interval and return the corrected (master) time in seconds + nanoseconds. Optionally, retrieve corresponding audio time.

Note

If no sync messages have been received, master time and local time will be the same.
