GPS Signal Lost in IGO when not in focus

[pants001]

Anyone else have an issue with IGO, that when I switch to desktop or another app, after a few seconds i hear "GPS Signal Lost"
Its rather quick to re-establish a connection when i switch back but seems weird to not get a signal only because its not in focus.
While in focus its rock solid, never drops out.

Setting or known issue?

Always, but I've been got used and don't care...

Snap. Always does it.

It has to be an Android issue I had a Pioneer Navi unit (they use iGO) never lost signal once locked in, well as long as I didn't go in to a tunnel or parking structure, switched to Android and every time I look away it drops GPS but only for a second or two. I believe there is an advanced audio setting to mute the announcement of GPS signal loss, but I cannot remember if it's a GUI option or if it needs to be put in the sys.txt.

Try this settings in SYS.TXT:

[sound.announcer]
gps_signal_lost = 0; disables voicemail alert "lost signal GPS"
gps_disconnected = 0; disables voice notification "GPS turned off"

[sound.announcer]
gps_signal_lost = 0; disables voicemail alert "lost signal GPS"
gps_disconnected = 0; disables voice notification "GPS turned off"

That may be a viable option, when its in focus i never loose signal....so really its just the voice announcement that annoys me when i switch to another App.

I used to use an app called active GPS, can be set to acquire a gps lock and keep it on boot, not sure if you are really losing the gps lock or if Igo just thinks it is.

Im not losing signal no......Its approx 5 seconds after IGO loses focus and it regains the signal immediately after i switch back.
Perhaps this is intentional to allow another App access to the GPS Signal.....ie only 1 App can have access at once, so they only keep it during focus?

Not sure but its peeing me off

Ill check if theres anything buried in IGO settings or the alternative (Not that i like working around a problem) is to quieten the "Lost signal" audio.

Do you also have a weather widget running with its location based on GPS signal?
Maybe that app requires a temporary connection to the GPS port (that might not be shareable between more apps)...

Ye possible, I also noticed a setting in GPS menu to allow location based services. So might try with that off.
I'll have a play around and report back. :silly:

In Android there is no problem for multiple applications to use GPS signal at the same time. You can run 5 navigation apps and another 5 tracking apps at the same time if you have enough RAM. The OS access the GPS sensor and shares the information to apps.

The question is, what really happens. If you continue with iGo in the background, is it still navigating you? Do you hear the correct voice commands or is it really lost and has no idea where you are?

For me all Navigation application work even in background. They have a service (identified by an icon in notification bar) that runs even if the main app is in background. You should also check the GPS icon in navigation bar to see if GPS is shut down.

I'm not completely sure about the following, but IMHO there is a difference between the smartphones and the MTCB head units for which regards the GPS receiver.

In fact, while generally in a smartphone processor (ex. Qualcomm) the GPS receiver is included in the chip itself, AFAIK in a Rockchip processor (ex. RK3188) the GPS chip is not present, but should be externally connected to the system through an internal serial connection (USB?) and managed by the MCU: for this reason there might be some sharing problems among apps, problems not occurring on a smartphone integrated architecture.

Ye thats interesting coz this morning i had to go somewhere and used navigation as apposed to just having IGO open on Map.
When Navigating to a destination, you can swap to desktop and other apps and it still guides you with no Lost Signal being mention.

So its only when you have maps open, not using a route navigation and you put IGO into the background.
I assume its IGO giving up the lock on the signal for some reason.

Same issue. IGO drops GPS when focus is lost.

I just installed a new head unit 4.4.2 and I have the same issue with IGO. I will try a few things and see what I can find as well.
Will report back if I solve it. It is bloody annoying. I am positive it is an Android thing, not an IGO issue.

That would make sense, it would be a battery saving feature, no need for a persistent GPS lock (that sucks battery life) if you are just following your location on a map (when the map isn't in focus anymore) but when navigating you want the persistent lock so you can continue receiving directions regardless of what app has focus. I suspect a lot of GPS apps act this way, they just don't announce it.

I think your right!

 

[jakejm79]

Possibly
Google maps acts that way, with maps open, if you open another app, the GPS icon disappears on my phone, but comes back as soon as I refocus on maps, but if I am navigating somewhere then the icon stays there.

 

[gk66]

Not that it offers you any help but my gps icon is on all the time regardless of what app is or isn't running.

If the above theory is correct then your answer may lie in the power saving and lox location settings.

Lox is a typo!

But on a smartphone this battery saving behavior doesn't happen...
And on a HU there is no battery at all and no battery saving needs, on Android all apps should be able to detect if the device is on battery power or currently external power supplied...

It does happen, test for yourself, but the battery will drain quicker with Maps open and an active GPS lock rather than when another app is in focus and no GPS lock, that is also why the mode to not use active GPS is called battery saving.

Take that up with the developer, but I doubt they will build in an option that is only useful to a very small number of users.

Personally I don't understand why you need the map window open if you aren't actively navigating somewhere anyway.
