[devel-rc-proposed] GPS not working

[slash]

Gents,
With the image 2017041968380 the GPS is not working :

root@ubuntu-phablet:~# test_gps

Some other input :

Regarding the error msg : Diag_LSM_Init: Failed to open handle to diag driver, error = 2

I've found a similar error msg for Firefox OS and Nexus 5
https://bugzilla.mozilla.org/show_bug.cgi?id=1107742
They fixed it by the commit in the bug https://bugzilla.mozilla.org/show_bug.cgi?id=1112175

It's seems a permission issue defined in BoardConfig.mk

It's so far out of my capabilities to assess if this is applicable or not.

And the last log i can pull is :

less /var/log/syslog |grep gps
ubuntu-phablet kernel: [ 1024.272978] msm_ipc_router_send_to: permission failure for test_gps

This msg makes me think the proposed solution could help.

Interesting point;

I cannot diagnostic the gps as mentioned above, but today the GPS worked !
So i've tried with success Unav and acrivity tracker.

So if possible we can change the bug title as "impossible to diagnose Gps".

Hi,

Still no GPS working for me, even after recent update... Not an expert but if someone can tell me how to log from my phone, I'll be happy to participate.

Jean-Paul,

Simple verification
Did you try to launch Unav for instance outside, not under a roof, without a protection for your phone and wait up to 10 min ?

Otherwise you can generate, via adb_shell :
less /var/log/syslog |grep gps
tail -f /userdata/system-data/var/log/upstart/ubuntu-location-service.log
test_gps

But in my case the output is negatif while the GPS works.
