I am a new user with a Nexus 7 2012 tablet. This tablet doesn't have the best GPS antenna in the world so it tends to lose lock when I have it mounted on my leg in the cockpit. I found this out while using Avare and purchased a Dual 150 Bluetooth GPS receiver to insure good reception. With Avare, there was an extra app that gets loaded to facilitate the use of both Wi-Fi and Bluetooth. I recently added a Raspberry PI ADSB in receiver and upgraded to IFly software. Both the ADSB receiver and the Bluetooth GPS worked fine with Avare. I find that with Ifly I can go to "Connected Wireless Devises" and select Free Flight and the receiver works fine. However there is no place to tell the software to use either the internal GPS or an external Bluetooth GPS. It doesn't appear to receive Bluetooth at all. I loaded a generic Bluetooth GPS receiver app and can get the software to lock on, but this is a lot of extra hassle. Am I doing something wrong or missing something?
