Please see the attached The patch is validated in my pc with 4.18 version and works fine. If it's ok for you please merge it into upstream. Thanks -----Original Message----- From: Marcel Holtmann [mailto:marcel@xxxxxxxxxxxx] Sent: 2008年12月12日 9:56 To: Li, Zhigang Cc: linux-bluetooth@xxxxxxxxxxxxxxx Subject: Re: To enablue DID in coming bluez release Hi Zhigang, > Could you please enable this profile in the coming release? > To update: > Add VID,PID,VER setting in main.conf > > I think the parse_config also need add code in order to parse these value to main_opt.did. I was expecting that you send me a patch for it. Regards Marcel
