What steps will reproduce the problem? 1.Select BTstack keyboard app (Apple BT off) 2.Tries to open BTstack - pinwheels for ever - alternative BTstack will not load 3.Cannot exit cleanly and cannot re-eneable Apple BT without hard boot

What is the expected output? What do you see instead? Expect keyboard selector but simply get BTstack start-up pinwheel

What version of the product are you using? On what operating system? iOS 4.01, iPhone 3G, BTstack keyboard 1.0 - 25570, ultrasnow 1.2.4 - this is a recent upgrade but everything else works OK

Please provide any additional information below. removed & reinstalled - cannot go back a version as cannot find resource

I can confirm under these circumstances: go to the BTStack settings in the Preferences dialog and you will see the current BlueTooth driver selected is "None"; selecting either BTStack or iOS causes the selection to get a spinning wheel that doesn't resolve after several minutes. Before I installed BTStack, I could send AD2P messages to my car and answer and dial and transfer phone numbers between my car and my phone. Since installing BTStack, my car (a 100% Electric, Nissan LEAF) doesn't see my phone at all. After uninstalling the BTStack software, even the iOS Bluetooth profile can't be loaded and my car still can't see my phone. This worked before your software, and I'd forsake said software if I could just get the original BlueTooth functionality back, but the uninstall makes this impossible! HELP!!

I'll release a new version of the BTstack package in the next days. However, I don't think that will solve any of your problems.

@spida: please check /var/log/syslog for hints on what's going on. (install "syslogd to /var/log/syslogd" and reboot if you don't have that already installed)

@timehorse: in your email you wrote that your Wifi is broken. If that's the case, I'd expect that Bluetooth is broken too, both are handled by the same chip and use the same RF antenna for sending on the 2.4 Ghz band. I'd suggest to reinstall iOS and check Wifi and Bluetooth before Jailbreaking.

Thanks for checking on this Matthias,

My phone's WiFi died from overheating while using TomTom since the mount was getting far too much direct sunlight. The BlueTooth was working perfectly every morning since I got my car until the day I installed one of the A.D. emulators which forced me to install BTStack. I can't switch back to the iOS stack in the UI and because it defaults to None uninstalling seems to leave it at none with the iOS disabled. Also, I had a repair shop check my WiFi antenna and the one in my phone is a new one; the WiFi will work if I put the phone in the freezer for a while; typically for about an hour after I remove it from the freezer. But I know a factory restore would bring my BlueTooth back, so it must be software. I'm proficient with unix and would be happy to ssh into the local host and try any commands you might suggest to further determine what may be the issue. Thanks again and any help will be greatly appreciated. I'm sure BTStack is better than the iOS stack and would prefer to use yours if possible, but I would at the moment like to be able to communicate with my car but keep my PDANet for which I have a valid license.

Anyway, listen, I just wanna say you are a very skilled programmer and I appreciate your effort. If you can help me with this, I'd be eternally grateful. Thanks!

@timehorse: well, please go ahead and restore, test Bluetooth, and then jailbreak again. I see no reason why BTstack prevents iOS Bluetooth Stack to work (at least not after a full reboot).

It took me days to arrange my icons in all the right folders the last time I restored since backup never seems to get that straight. All in all, restoring and rejailbreaking would be like pulling teeth for me since about 3 weeks ago my jailbreak on 4.1 failed to get out of boot so I factory restored to 4.2.1 and then after seeing everything working fine (except the wifi outside of the fridge) and verifying the blue tooth had no issues, I jailbroke since I love PDANet and having custom backgrounds and boot logos. Then I spent days with Cydia trying to recover apps since Cydia loves to crash and take down springboard on this phone. So, if you want me to go through that torture again just to prove that BlueTooth is perfectly functioning from a hardware point of view I will do that but I said before, I ssh into my phone regularly and can run any test procedure you can devise. I know Tab+ broke Safari but even loosing the primary web browser isn't worth the torture of restore, rearrange icons, find the elusive version of redsn0w that supports iPhone 3G running 4.2.1 (since they stopped supporting 3G in recent versions) and then suffer the tortured loading and reloading of Cydia. But if it will get my BlueTooth back, I will consider it. But please be very sure of your reasoning, sir, because if I restore my phone, bluetooth comes back and then install Genesis A.D. and am forced therefore to install BTStack and this irrecoverably breaks my BlueTooth again, rest assured, I shall be a lot less sanguine during our next encounter.

So, that said, are you absolutely sure there isn't some log file or other testing application I can run on my phone to debug this issue? I've rebooted numerous times and still the BTStack setting in Preferences defaults to "None" and can't be switched. I know BlueTooth is working from a hardware perspective since just last week I was making calls from my car using the BlueTooth interface and was able to play Pandora through the speakers when I bought the car on 2 November. It's a software issue, of that I'm 100% sure. I write software for a living and although I've not written software for the ARM processor (save some iPhone apps), iOS is pretty much just BSD and that I can handle. So, is your solution still to restore?

wow. thanks for the detailed explanation.

Ok, before restore, I suggest to just deinstall BTstack and reboot. De-installing BTstack removes all traces by it, and then you're left to the mercy of iOS :)

To deinstall, either run dpkg from the command line (check command line args), the package name is ch.ringwald.btstack, or enable developer role in Cydia->Manage->Edit, and remove it there. Then reboot, and good luck.
