I still got connection problem after last post. Then I've found I turned "Location" off in the setting. Turn it on and I can connect to XIM APEX. Turn it off, connect failure. So I am sure "Location" needs to be on. Please notice the users at the connect screen.
the solution is typical to one that would work for burping radios after flashing phone with unstable homebrew firmware are you running a custom Rom on your phone?
I don't believe that's related. I never have Location enabled on any of my Android phone/tables and test with 8 of them which vary in brand and Android version.What type of phone do you have?
What type of phone is it? Also, do you have any issues with other Bluetooth devices if you don't keep Location on?
So with Location off, your earphones won't show up in the list?Also, to verify, you aren't pairing to your XIM APEX through Android's Bluetooth devices list, correct?
