With BT Stack, to change Inquiry scan / Page scan timing, below API can be used.
* HCI_Write_Inquiry_Scan_Activity()
* HCI_Write_Page_Scan_Activity()
According to the API document, the default values are as below.
(1) Inquiry Scan Interval -> 0x0800 (1.28 sec)
(2) Inquiry Scan Window -> 0x0012 (11.25 msec)
(3) Page Scan Interval -> 0x0800 (1.28 sec)
(4) Page Scan Window -> 0x0012 (11.25 msec)
When Inquiry and Page scanning while audio sink working (A3DP), radio (RF) should be shared with audio and scanning.
In this case, can we know the optimal value of both interval and window, for better discoverability/connectability and audio quality?
(There is trade off between scanning performance and audio quality.)
Thanks and regards,
Hayden
