In the HF device that I am using, the manual they have given is if we press particular button, it will mute the call. from logs I got is AT+VGM=0. may be they are telling mic gain of 0 as mute. Since when I mute( mean VGM=0) then UI is not getting updated and showing mute icon. So i took reference as VM=0 then updating the GUI. Is it valid to update mute icon based on VGM value?

Hence when you enable mute from HF, you must unmute from HF. > On Sat, Sep 25, 2010 at 8:41 PM, Pavan Savoy <pavan.sa...@gmail.com>wrote: > >> HFP can support mute right? among voice dialing, redialing etc.? isn't >> this what makes hfp different from hsp? >> in any case i was interested to know how the sco connection was >> established? via the android gui or via some test application? >> >> On Sat, Sep 25, 2010 at 2:13 AM, Suresh Chandra Pal < >> sureshchandra...@gmail.com> wrote: >> >>> Guys, >>> This is a little bit confusing for me.
