Hi, efter a long search i found it a way to use Gps without any program (you are here gps...) My GPS model is: BU-353S4 Get sounce code android 4.4.2 Modify files: Source/device/fsl/udoo BoardConfig.mk BOARD_HAVE_HARDWARE_GPS := true USE_ATHR_GPS_HARDWARE := false USE_QEMU_GPS_HARDWARE := false init.rc # Set GPS serial and reset GPIO pin - delete all is under gps section(next 4-5 lines), in case you don't use that . and add this 2 lines. setprop ro.kernel.android.gps ttyUSB0 symlink /dev/ttyUSB0 /dev/gpsdevice Source/device/fsl/imx6/etc ueventd.freescale.rc add - /dev/ttyUSB0 0660 system gps Modify Kernel: make -C kernel_imx menuconfig and check : <*> USB Prolific 2303 Single Port Serial Driver Build Android and put on sd card. Go to : https://github.com/dipcore/gps-glonass-android-driver download ''gps.default.so'' and copy in /system/lib/hw/ Modify /system/build.prop and add : ro.kernel.android.gps=ttyUSB0 ro.kernel.android.gps.speed=4800 ro.kernel.android.gps.max_rate=1 4800 (in my case) Reboot. Have Fun! Maybe some steps is not needed but this i done .
