GPS stopped working

Bug Reports

#284

AGPS_CONFIG_INJECT = 1 is the default, so that should be ok. You probably already have changed SUPL_HOST to point to Google.

The culprit is mls\online_enabled=false as can be seen in the source of geoclue-hybris.

Without setting this to true, m_agpsOnlineEnabled will be false and no online services will be considered.

The interesting question will be, if you get the AGPS callbacks. If everything works, you will see the AGPS callback pair

AGNSS type: 1 status: 1
...
AGNSS type: 1 status: 2

exactly once. With wrong or missing certificate, I got two pairs indicating a retry.

#285

ok, I changed that, I don’t see any difference,

BTW: where did you see this AGNSS type:1 status: 1 ?

Currently my gps.conf is this one:

#286

That’s only the log of geoclue-hybris starting up. The SUPL request is issued, when a client connects, e.g. when you start gpsinfo.

#287

ok,

How can I debug all the gps stuff? (yesterday I went to walk, and nothing was working, no gps, no nothing) and it’s sad, because I like the operating system a lot, But to be daily phone, I will need gps. (not for the car)

Thanks!

#288

There’s not much more you can do because GPS is almost entirely handled by the Snapdragon 630 SOC. One more thing is to run

$ /system/bin/logcat

to see output of android.hardware.gnss@1.0-service-qti. To understand at least some of the log messages you have to look them up in the source.

Do you see the GlobalSign Root CA - R2 cert on your device?

# tail -c +1065 /dev/mmcblk0p6 | tar tvf - SUPL
drwxrwxrwx root/root         0 1970-01-01 01:00:00 SUPL/
-rw-rw-rw- root/root       804 1970-01-01 01:00:00 SUPL/Equifax.crt
-rw-rw-rw- root/root       958 1970-01-01 01:00:00 SUPL/GlobalSignR2.crt
-rwxrwxrwx root/root       879 1970-01-01 01:00:00 SUPL/SuplRootCert

If not, AGPS won’t help too much.

#289

I tried right now, going to buy, and at least gpsinfo showed me some satelites, and detect I was in my country… It was not a good precision (the precision was the hole country) but at least, I’ve got something.

I will take a look later,

Thanks,

#290

I don’t have it. Is it not possible to install it from somewhere?

#291

With same config as yours and Cellular data only (no WLAN) I get the following:

I’ve only got this

[root@Sailfish etc]# tail -c +1065 /dev/mmcblk0p6 | tar tvf - SUPL

#293

Maybe. The common way offered by other Android vendors is to provide a way to upload it to the SOC, but this does not seen to be used by Sony (AGPS_CERT_WRITABLE_MASK=0, i.e. no free slots) and SUPL_TLS_CERT doesn’t seem to be understood.

A second way is to flash an Android version that has the cert. I have downloaded an Android 9 (H3113 50 2 A 3 77 Customized-DE), that has it. If that’s a solution is untested at least by me. But I will try when Google changes its cert, which is likely to happen before December, when the root certificate expires, and as soon as Sony provides Android9 roms with the new certificate.

#294

This message comes from here and shows, that you don’t allow data connections for AGPS, i.e.

mls\online_enabled=false
#295

I have checked in /etc/location/location.conf:
mls\online_enabled=true

#296

That’s strange. The problem is m_agpsOnlineEnabled=false in line 1159, which is computed at lines 1119-1120 of the same file. hereAvailable() is most likely false hence mls should be enabled and allowed (even if it no longer works). No idea why this fails for you.

#297

seems the GPS is working fine in my phone, only needed maybe one hour in device only. (with the other configurations don’t do nothing)

But now seems working.

#298

Are you saying it took an hour to start working? How long will it be the next time you start the GPS?

I can get the GPS in my XA2 to work too, but it takes at least 15 minutes each time from a “cold” start, i.e. one which is more than a few hours since the last time I used the GPS.

Having to wait 15 minutes makes the GPS useless.

#299

I will need to see what time takes from cold to work, because yesterday night, I tried inside the house, and it was still working fine, after some hours stopped.

#300

As I said earlier, a new device could require up to one hour to get a valid lock. It needs to rebuild the satellite almanac, then the ephemeris data, and only then it will be able to get a lock. This should only be true for the very first start (or after the phone battery is removed, if the GPS has no backed-up memory).

#301

MLS is working on my XA2. It obtains a position quite quickly, but only with a horizontal accuracy of 9000 metres. In other words it is not very accurate.

When I’m at home the location symbol is about 1 km from my house. I guess it is where the cell phone tower is.

An accurate lock isn’t obtained for about 15 minutes.

My X has no sim card so therefore no MLS gets an accurate lock within a minute or so.

#302

Same for me, horizontal accuracy with MLS is always 9000 m.

AFAIR all I did was replacing the server adress. The changes in the config file remained, but I was only able to pick up GPS signals that day and the day afterwars. No luck after that.
