Hi, in AIO-3399J it's available out of the box, but if you want to use GPS and LTE you need to do some preps:
1. Enable autogps in EC25 via AT commands
2. Edit u-blox.cfg http://wiki.t-firefly.com/en/AIO ... modification-method - set SERIAL_DEVICE to /dev/ttyUSB1 and set baud rate to 115200
3. set ro.factory.hasGPS to 1 in /system/build.prop
