How to disable internal GPS?

[PitrsRS]

Hi, i have a little problem. If I have disabled internal GPS (in system settings is OFF), and try to use BT GPS, app will still try internal not external and for BT is status Not Available, but is allready connected. Is there any option in app to "hard" disable internal GPS and use only external? I dont want to use internal GPS because is too slow (even 1Hz external GPS wich I have is better and faster)

Xperia P
Jelly Bean 4.1.2

Thanks for reply

Please disable any GPS helper apps first. Make sure you have paired your GPS with the phone. Enter LapTimer and select Sensor List. Press the +BT button and select the paired GPS device. Confirm it is a GPS. LapTimer will use this GPS now and disable the internal GPS automatically.
