Does btstack GPS work on iOS 4.0?

[GoogleCodeExporter]

Hi,

I've been using btstack GPS (latest version) on my iPod Touch 2G for a while 
now, and it has always worked great. However, since I've installed iOS 4.0 
(jailbroken with Redsn0w 0.9.5b5-4, using a ipsw you can find here: 
http://tinyurl.com/23owvuq) the app causes the springboard to crash. Even when 
you reboot the device, it remains in safe mode. In others words, there is no 
way to open the app and the only way to solve the problem is to uninstall the 
app. 

So my question is, what do you think is causing the problem? And of course, is 
there a way to prevent and/or solve it? 
Thanks!

Daan

BTstack itself works on iOS 4.0. The individual apps don't work yet - but 
that's mainly because backgrounding does not work.

I've installed BTstack GPS on my iPhone 3G with iOS 4 and used it as usual. No 
crashes for me. 

Can you check if you got an Crash Report for that in 
/Library/Logs/CrashReporter?
What kind of device do you use?

I also received an email from another user with the same problem.

Thanks for your almost immediate response :)

Unfortunately, there is not crash report in /Library/Logs/CrashReporter. (using 
winSCP)

As for my device, iPod Touch 2G 16GB, MB model, 4.0 8A293.
Just summing up some info, I hope that's enough.

A quick update: I've also tried the sn0wbreeze jailbreak, but unfortunately no 
luck...

For the record, I've used PwnageTool on my iPhone 3G.

Please delete /Library/MobileSubstrate/DynamicLibraries/GPS-Support.dylib and 
see if that fixes the crashes - it won't allow to use the external GPS in other 
apps.

I am also using 2nd generation iPod Touch, and encountered exactly the same 
problem. The btstack gps simply crash my springboard. I also tried roqyBT, but 
it didn't work also. 
Now with iOS4.0, I cannot use my external GPS anymore. Kind of regret updating 
it.

I'm willing to try if deleting that file solves the problem, but unfortunately 
I really need to use the external GPS with other apps... 

It's shame to hear that roqyBT doesn't work either, I was going to try that 
today. 

What I notice, is that the problem seems to occur on the iPod Touch devices and 
not on the the 3G/3GS (and thus on devices that don't have GPS natively?)

hm... interesting observation with regard to "only crashes on devices without 
GPS". I'll look into that later. And yes, that reminds me that BTstack GPS is 
hooking into SpringBoard (forgot about that detail) exactly to override the 
system-wide GPS capability. That's a good point to start... thank!

Nice. I found the bug without touching the device. The call to add the "gps" 
capabilities fails (with a crash) because Apple renamed a method parameter from 
"removeCapabilities" to "resetCapabilities".

I guess I can post an updated GPS-Support.dylib here until tomorrow.

Ok, that solves the problem on non-GPS devices, but for full iOS 4 support, 
I'll have to figure out why BTstack GPS is killed by the OS when running in 
background (yes, it works with Backgrounder but I'm not going to suggest that).

Thanks Matthias, I'm looking forward to it!
I also notice backgrounding works a bit different on iOS 4. I also notice it 
with music. I used to play music with Pwnplayer on the background, but now it 
has stopped working :/

ok. here's the updated GPS-Support.dylib that "should" work on iPod touches - I 
only have a iPhone 3G (with GPS) and an iPad (without 4.0) to test with.

To install:
 * first remove the old copy: rm /Library/MobileSubstrate/DynamicLibraries/GPS-Support.dylib
 * then install the new one: e.g. cp GPS-Support.dylib /Library/MobileSubstrate/DynamicLibraries/

With this, SpringBoard shouldn't crash anymore, the app should work. If you put 
the app in background using Backgrounder, you can actually use it. Note... 
that's just a quick workaround, not a solution.

Yep, the crashing has stopped, good job!
Only one thing left to do ;)

I saw an update on cydia about supporting ios4 in 1.4-25565, but the version 
provided is still 1.3-25246. Will v1.4 be online very soon? Thanks!

Hi.. the packages and the descriptions are managed by different entitites (me & 
BigBoss). The update for all BTstack apps is live now..

Here's the tweet: All BTstack apps fixed for iOS 4. BTstack Keyboard, Mouse, 
and GPS updates are live in Cydia - but no BTstack icon in status bar still.

Yes, no icon, but all seems to work well so far.. So I understand this update 
has been done by BigBoss?

Original comment by dan0...@gmail.com on 26 Jun 2010 at 2:22

[GoogleCodeExporter]

Thanks for the feedback. BigBoss is just the repository that hosts my software. 
They are not involved in development.

Hi. Please let BigBoss know that they still limit only OS3 users to purchase 
this app, despite that it is compatible with OS4 now. Thanks.

hi. thanks for the note, and sorry for the delay. I just got informed by other 
users, too, and try to have the purchase block for 4.0 removed in Cydia Store. 
Btw., that's managed by Jay Freeman (saurik). Will let you know when I reached 
him.

The purchase block was just removed. If you intended to buy BTstack GPS and 
you're on iOS 4, feel free to do it NOW :)

Still cannot purchase. Can do that for BTStack Keyboard, but not for BTStack 
GPS. Maybe I need to wait a little bit more.

Sorry, the block seems to be there still. It _will_ get removed ASAP, but I 
cannot do it myself.

Hi.
Is it possible that the purchase button is activated this evening?
(sorry for my bad english)

Depends on your timezone. :) Have to wait to reach saurik for this.

been a nice Widget with tomtom West Europe.

I know/hope for that. Unfortunately, I cannot control stuff in Cydia Store and 
cannot reach saurik at the moment. Usually that's not an issue. Sorry.

Finally! The purchase block for iOS 4 has been removed for BTstack GPS. Go 
ahead!

@intelo72: why did you choose to comment on this closed "BTstack GPS on 4.0" 
issue?

In your screenshot, no devices are listed. You have to make your external 
Bluetooth GPS device "discoverable" to make it seen and connect to it.
