[Bluez-devel] patch to add read/write inquiry scan type functionality

[Bluez-devel] patch to add read/write inquiry scan type functionality

[Albert Huang]

[-- Attachment #1: Type: text/plain, Size: 167 bytes --]

The attached patches add reading and writing of inquiry scan type (for
interlaced inquiry scan)

One patch is for libs, the other is for utils

Regards,
Albert

Hi Albert,

>

I applied the patch and changed "istype" to "inqtype". I also added a
section in the manual page about the new command. You also forgot to add
decoding support for it to hcidump.

Regards

Marcel
