Thanks for this help. With AGPS I got a fix within a few minutes and GPS reception works as expected Wink

Just wanted to report I am unable to get a fix on my new pinephone manjaro ce edition.
I've installed the updated modem firmware from https://forum.pine64.org/showthread.php?tid=11815 so I have "EG25GGBR07A08M2G_01.002.07"
As well as the AGPS fix mentioned in this thread as can be seen from the assistance server output in the console output I've included below.

Code:
[root@manjaro-arm ~]# mmcli -m 0 --location-status
Code:
  --------------------------------
Code:
  Location |        capabilities: 3gpp-lac-ci, gps-raw, gps-nmea, agps-msa, agps-msb
Code:
          |              enabled: 3gpp-lac-ci, gps-nmea
Code:
          |              signals: no

      | tracking area code: XXXX
Code:
      |            cell id: XXXXXXXX
Code:
  --------------------------
Code:
  GPS  |              nmea: $GPGSA,A,1,,,,,,,,,,,,,,,,*32
Code:
      |                    $GPRMC,,V,,,,,,,,,,N*53
Code:
      |                    $GPGSV,3,1,10,01,,,,02,,,,03,,,,06,,,,1*61
Code:
$GPGSV,3,2,10,10,31,210,,12,33,042,,15,,,,16,,,,1*62
Code:
$GPGSV,3,3,10,17,,,,18,,,,1*6A
Code:
      |                    $GPVTG,,T,,M,,N,,K,N*2C
Code:
      |                    $GPGGA,072623.52,,,,,0,,,,,,,,*4D

I've tried waiting for a number of hours and based on what I can understand from the output on the GPGSV line it looks like it's tracking 10 satellites with varying degrees of signal strength. I'm unsure why it's unable to get a fix though.

Is anyone else having difficulties, or does anyone have any other tips?
Thanks!
