Status GPS on Android-x86

[BenjaminWebb]

I was wondering what the status is of running a gps on android x86. i
have a surfstar II usb one currently supported under Ubuntu but I have
yet to find gps software with descent routing and traffic etc. I see
android as the perfect operating system for a car tablet or computer.
Just waiting for the support to get there.

I believe you have to implement your own LocationProvider to process
the NMEA your GPS device and add this LocationProvider to the Android-
x86,
see http://developer.android.com/reference/android/location/LocationProvider.html

Then, you can use any GPS app from the Android market ..

Obviously, the hard part is to implement and add such LocationProvider
service to the Android-x86.

[BenjaminWebb]

No that service looks easy to program I just need the drivers and gpsd
to load so I can convert from gpsd to the location provider unless you
guys are looking to reinvent the wheel.

If you get that working, I'd be willing to purchase the software from
you.

Let me explain way that I run GPS on android-x86.

1. First of all, you have to search and download, 'gps_freerunner.c'

2. Move 'gps_freerunner.c' to 'hardware/libhardware_legacy/gps/'
folder.

3. Modify 'hardware/libhardware_legacy/gps/Android.mk' like below
-------------------------------------------------------
# Use hardware GPS implementation if available.
#
LOCAL_CFLAGS += -DHAVE_GPS_HARDWARE
# LOCAL_SHARED_LIBRARIES += $(BOARD_GPS_LIBRARIES)
LOCAL_SRC_FILES += gps/gps_freerunner.c

5. For your USB or Serial GPS Device, your kernel must recognize !!!
For me, I use USB-GPS(PL2303), and kernel recognize by pl2303.ko
kernel module(CONFIG_USB_SERIAL_PL2303).
You simply check your device driver in ubuntu. However, default
android-x86 kernel does not include
pl2303 module, and there is not much driver for usb-to-serial module.
So, you have to customize kernel config and build your kernel.
After recognizing GPS device, you can check your device in '/dev/',
like '/dev/ttyUSBx' for USB2Serial.

You must add property for GPS device like below.(for example, assume
ttyUSB0)
> setprop ro.kernel.android.gps ttyUSB0

If you want to view demo, you can see GPS usage demo in
'www.androbox.co.kr > screenshot'.

Hi,
How about the GPS mouse through Bluetooth?

[kwok]

Hi jch.shin,

I made a new froyo build using the information from your post (instead
I changed the codes to use /dev/rfcomm0 to input the GPS data).

I'm using the internal bluetooth chip of my eeepc to connect to a
Bluetooth GPS device.
I manually created /dev/rfcomm0 and have checked that I could received
the NMEA sentences from the remote BT GPS (using cat /dev/rfcomm0).

However, the Andoid system could still not find a gps provider.

Do you have more suggestions how to get this working?
Further, I enabled the debug logging of gps_freerunner.c, but I did
NOT see any debug message on the console.

Hope you can help.

Regards,
Kwok

[kwok]

I found out that I might need to remove the following line in .../gps/
gps.cpp as well:
#ifdef HAVE_GPS_HARDWARE

because I never set this.

Doing another build ...

[^_^]

Checkout http://sourceforge.net/p/bluegps4droid/home/
It's an app that creates a mock provider from bluetooth gps devices.
Only for android 2.X
Greetings.

[richi]

Great! It run well with google map, I will put them in apps.

Finally get it working :)
I need to remove the mode check in function
freerunner_gps_set_position_mode(...) :
/*
if (mode != GPS_POSITION_MODE_STANDALONE)
DFR("%s: called with bad GpsPositionMode !!", __FUNCTION__);
return -1;
*/
as mentioned in http://d.hatena.ne.jp/yamanetoshi/20100722/1279774279

[ady2k10]

bluegps4droid apk is working on Froyo-eeepc. I have tested it.
It can detect bluetooth on mobile phone.

I'm tracking right up to step 5 in which you lose me.

[kwok]

What went wrong??
What GPS device (usb or bluetooth) your're using?

You need to figure out:
1. if the kernel 'recognizes' your device
2. if yes, check what device the kernel has created (/dev/usb-xyz-)
3. if no, you have to customize the kernel to load missing module

Hi,

Currently I'm working on a GPS project. I need to write a GPS HAL. My
board is BeagleBoard and I'm working with a BU-353 GPS.

I have followed the steps in http://d.hatena.ne.jp/yamanetoshi/20100722/1279774279,
but I just cannt receive the correct NEMA message. Can you help me and
tell me how to debug it? I have suffered it for a long time.

Yours

Crazy Frog or anybody,

Did you ever get this figured out using your BU-353? I'm looking to get the same thing working on my Pandaboard.

Thanks!
