@Flohack I tested indeed indoors - I'll check if outdoors works better.

Thanks. I made some progress: After waiting a few minutes test_gps did something (and repeatetly does this now without delay):

However, Mapping apps (uNav, google maps in morph) do not work. They do not find a position at all. I tried both with 20 minutes waiting time. Nothing happens. Both, uNav and morph, have permission to access gps.

Any idea?
Thanks!

Thanks for this, I was not aware. However, also running test_gps as root does not lead to success:

sudo test_gps 
[sudo] password for phablet:

Still an error, any ideas?

Hi,

I run Ubuntu touch on my Nexus5 for a while already. Great. However, I never got GPS working. I've tried the "wait 5-10 Minutes" method several times - no success. Here is what test_gps results in:

phablet@ubuntu-phablet:~$ test_gps
*** setup signal handler
*** get gps interface
*** device info
 id = gps
 name = loc_api GPS Module
 author = Qualcomm USA, Inc.
*** init gps interface

 **** Thread wrapper start (start=0xb6a617c5, arg=0x16dac88) ****

*** start gps track
*** gps tracking started
*** tracking.... 
*** set capabilities

*** tracking.... 
*** tracking.... 

tracking... repeats then without any other result. "open: Unknown error" looks very suspicious? ... Note that the error code is different in different runs. Google-ing did not lead to useful insights. Any idea?

(Note: I already re-flashed radio to several version - no sucess. Latest try: radio-hammerhead-m8974a-2.0.50.2.30.img )

Thanks!
