Symbian internal GPS

[Xf0ur]

Hi, I have an old symbian phone which i want to use its internal GPS to provide location for Raspberry pi.
I succeeded doing so by using Bluetooth GPS provider apps.
However, i would like to use USB GPS as well.

Here is some log:

P.S. The phone creates ttyACM1 acm device and i can actually see GPS data coming when i run cat /dev/ttyACM1 after having GPS fix.

Any help?

Could it be that because you already have a serial driver claiming the interface, android is not able to claim this for itself? Are you able to disable the driver?

Hi,
Thanks for replying.
The android build i'm using has HAL for serial GPS devices
I can only comment this line in build.prop
ro.kernel.android.gps=ttyACM1
Can you explain how i can disable the driver?

Edit: here is some other logs

Hi,
Are you able to use your android phone as an external GPS for your tablet via USB using an app like Share GPS then intercept the GPS data using your UsbGps4Droid app?

[freshollie]

I can only comment this line in build.prop
ro.kernel.android.gps=ttyACM1

Remove that line and see what happens?

Otherwise, if you have root access, can you run lsmod and send the output here?

No, USB Gps is just designed for serial GPS devices :/

I removed it, still see the same log errors

Otherwise, if you have root access, can you run lsmod and send the output here?

I do have root however lsmod doesn't show any loaded modules.

I think you should have the phone in hand in order to solve that issue.
Thanks anyway.
