[Android General] jago25_98:
I can't get any GPS at all. Using GPS Essentials I get no satelites visible. I've used "FasterGPS" to update the gps.conf setting away from HongKong and tried disabling EPO, A-GPS but this hasn't helped...

trying an external bluetooth GPS for now...

update: ok, the external bluetooth isn't working. the device can be seen but that's all. could be that bluetooth fix that I applied that caused a problem. anyone else had working bluetooth?

update 2: ah, we had a gps signal after 20-30mins of driving. so, very very slow updating with the internal GPS and Bluetooth GPS doesn't work either. Not good.

Anyone know how to search the source for "SENSOR_TYPE_MAGNETIC_FIELD" to find the kernel module for the compass at github in other ROM projects?

GPS source at Maguro to compare with X710D:

https://github.com/SlimRoms/hardware_libhardware/blob/jb/include/hardware/gps.h

Can't see any propreitory magnetic Z sensor in the src:

https://github.com/SlimRoms/device_samsung_maguro/blob/jb/proprietary-blobs.txt

update 3:

I thought this might be useful for anyone interested in the device. Since the kernel source is not released this device is already limited. How limited though?

Here's the kernel module list for quick reference:

root@android:/sys/module # ls

So we can see ipv6, apple kb, usb storage (not usb host?) but no nfs or samba so no networked drives for direct backup to the network.

Regards getting new modules, is there a similar device I can try to get modules from or do we need the source for that was compiled for this?

How can I help get the Bluetooth working? Does it work with the stock setup? Is there an app I can install to log what is going on?

Bugs I want to fix

1) Bluetooth - pairs but doesn't seem to transmit (with my gps or other people's handsfree devices)

2) Baseband modem switching between GPRS, Edge, HSDPA without any movement of the phone - it's switching without much change in signal and doesn't seem to favour the faster speeds

3) I can't get a data connection with WCDMA when that only is enabled (no auto), even though I have a good signal. There is actually no switch to turn off 3G... but I haven't seen 3G used when in auto mode yet. Does this work for you? Perhaps it's my SIM.

4) Compass would be good... but can we do that with source for other phones?

update 4:

Ok, the GPS Bluetooth was a mistake. It works, but I had to use a different app for some reason. You need to use "Bluetooth GPS" rather than "Bluetooth GPS provider" :)
