The beta release of SFOS 4.4 replaces your modified gps.conf
file so you need to backup or re-enable SUPL by modifying host and port.
I’m using europe NTP pool (uncommented in gps.conf
), changed SUPL host and port, other values unmodified. SFOS GPS configuration “high precision” selected.
The QCOM modem settings are non-volatile, i.e. once you patched your modem’s setting with suplpatcher
to use non-secure SUPL it should stay that way even after an OS update (modem land is not modified by Jolla usually).
That being said for a test I cleared my almanc and ephimeris data from the modem’s cache directory, rebooted the device (Xperia X) and started a new GPS session. Once the almanac (XTRA) data, NTP time and a rough offline MLS position was injected I got a fix within approx. 15 seconds indoors which means to me that SUPL still works after the OS update.
However days before the update (March 14th - 15th roundabout) SUPL wasn’t working for me, too for a reason unknown. Maybe XTRA servers, NTP or Google’s SUPL wasn’t sending data so I had to wait much longer than usual (like with SUPL not working, I did also reboot device to free any modem in-memory cache). It eventually resumed on March 16th.
TLDR; With 4.4 SUPL is still working fine (once patched).
