I paired BlueAnt ST3 speakerphone and Plantronics VoyagerPro headset with my BB-8830 without problems and decided to have a closer look at the settings.
options - bluetooth - BlueAnt ST3 - menu - device properties
the original settings look as follows:
Now, if from this screen you hit:
menu - refresh service list
the settings will change, "echo control" and "handsfree" service will disappear:
This doesn't seem to be correct, as BlueAnt falls under the category of "handsfree" profile because it supports voice dialing, redial and call transfer, features not available in "headset" profile (all those features still actually work ok in BlueAnt). I would expect that using "refresh service list" should have no effect on the settings shown on Device Properties screen. I'm wondering if it's a BB-8830 device software bug.
An attempt to use "refresh service list" with VoyagerPro resulted in a continuous hourglass, hitting Escape cancelled the process and no settings were changed.
