I'd like to get access to my position and gps data from the command line - surely that must be possible?

when maps is running, following command gives you lat,long

dbus-send --session --type=method_call --print-reply \
    --dest=org.freedesktop.Geoclue.Providers.Here \
    /org/freedesktop/Geoclue/Providers/Here \

something like

method return sender=:1.918 -> dest=:1.979 reply_serial=2
 int32 3
 int32 1421521856
 double 61.2342
 double 23.5406
 double nan
 struct {
    int32 5
    double 135.2
    double nan

maybe there is way to enable it also from command line, but didn't yet figure it out.

(Couldn't find a way to send a{sv} aka QVariantMap from cli)

Any idea on how to do it w/o Here/Maps, i.e. just having the GPS enabled in Settings?

Propably most efficient way would be to make a simple commandline tool for this purpose. Or maybe search internet for such written for Qt ?

Made small commandline app called position (also a learning project).

Altough i requested updates every second, it updates every 30 sec (?)


You can find readybuilt binary from mer obs (link valid for version 0.0.3)

While developing GPSInfo I was also seeing this "problem" about the interval, it seems to be something like a minimum. While there is no GPS fix, you will get updates containing the last known location in a lower interval, but if the GPS is available you will get updates as soon as they are available.

Yep, also noticed the same thing when working on modRana. Until it gets a real GPS fix, it uses some alternative approximate method to get a preliminary fix every 30 seconds.

This alternative method is most probably WiFi an/or mobile cell positioning using a remote service over the Internet - you send it the WiFi AP MAC addresses/mobile cell ids and it tells you your approximate coordinates.

And the 30 second interval is mot probably rate limiting so that all the Jollas (and other devices) using the API don't DDoS it out of existence or there could be some usage quotas Jolla bought for the API, etc.

Also given the approximate nature of the coordinates returned (tens of meters in best case, which is still quite good actually), it won't make much sense to run another request sooner, unless you are currently moving.

thanks. So in Jolla there is no way to have GPS position unless maps app is open?

I am interested in writing an app to track when I go into or out of a specific geographic area and I need continuous GPS fix for it to work ( 2015-01-20 14:14:22 +0200 )edit

Is it possible to compile this on the Jolla?
