BT Stack and Max Q Quantum 20Hz

Post by ProDarwin » Fri May 13, 2011 6:47 pm

So last weekend my co-driver and I tested Harry's Lap Timer using the iPhone GPS. The interface/software is great, but GPS resolution is too low. This week I jailbroke my phone with the intent of using our Max Q Data Quatnum GPS (20Hz) with it. If I go to BT Stack and connect to it, it I don't see any of the data. It just shows a google map with no location, # of satellites, etc. Am I doing something wrong? I haven't purchased full-version of BT Stack GPS yet, but I would assume the demo version would at least show me its working.

I know this is an unsupported use, but just wondering if anyone else has had this problem?

The full version of BT Stack works well. I have a Qstarz 818x. I have no connection issues. GPS works well. The speed on the speed overlay is not accurate at 10hz

Update rate displayed is reality / what is effectively received - almost always a little bit below spec as all the sensors drop a fix from time to time. I understand the question as a connection problem 'before' arrival in LapTimer. I'd ask the BTStack GPS people for support.

This is what I see in my version:

I'll see if I can ask the bt stack gps people. Wouldn't surprise me if it's a max q problem though :(

If the BTstack GPS demo doesn't even show the time, the communication with the GPS just doesn't work as expected.

Please send try once more and disconnect after a few seconds, then send me (iphone@ringwald.ch) the file /tmp/hci_dump.pklg from your iPhone.

If you are on Windows, look for this: http://iphonefolders.com/
With that tool you can easily access all of the iPhone file system. Of course you need a jailbreak, as for btstack.

Doesn't work on win 7 x64 :(

Is there a different way to get the file from my phone?

Edit: nevermind. I used ifunbox and got it. Sending email now.
