Hi folks,
I tried the suggestions from undrwater and powered off the neo,
rebooted it
and took care not to let it go into suspend mode, but GPS will not
work. I
also read
in the manual, that:
GPS
The fso-gpsd is a daemon waiting for gsmd connections, automatically
powering the device on and off. When a connection exists, it powers up
the GSM. In SHR Settings you can switch GPS completely off SHR Settings
-> GPS -> Manual> Off
so again: without SIM card no GPS?
Do not confuse "gps" and "gsm". fso-gpsd listens for gpsd connections,
not "gsmd connections".
GPS should work with or without SIM. I just tested it with
shr-full-eglibc-
ipk--20100721-om-gta02.rootfs.tar.gz and it's fine for me with no SIM.
Check that you have the right time, date and timezone set because if
these are
wrong it can lead to very long TTFF, or no fix at all.
i am pretty sure you can get a fix without having the time first. in the
position control panel the GPS time fields becomes right (UTC) fairly
quickly after turning on GPS, at about the same time the satellites show
up fuzzy.
if you have not used GPS for a while, it can take a long time to get a
first fix. take the phone out side for 15 mins.
With a clear unblocked sky, you shouldn't need more than 2 min for a
first fix. (with no agps data to help.) shr-settings has an option for
deleting agps data - use that if bad data is suspected.
The only times I have seen more than 2 min is when buildings/mountains
gets in the way, when trying to get the first fix in a moving car,
or when there is software errors. Bad agps data can give delays, or even
a "wrong fix" where you get some crazy positions followed by silence.
