OBD2 bluetooth and external GPS bluetooth

Post by doborder » Sun Mar 06, 2011 5:32 pm

In anticipation of Version 13 with OBD support, I was interested in finding out whether the iphone and also the laptimer pro can support both a ext bluetooth GPS and also a OBD 2 device to provide more information for accurate video overlay. Currently I have Qstarz BT GPS on a jailbroke iphone, but was interested in getting OBD 2 info on my video overlay. A little guidance please.

Hi,

By the way - LapTimer Pro v13 is available in App Store now (just a few minutes ago).

Although the PCX KiwiWifi (only supported OBD sensor currently) uses Wifi and your Qstarz uses Bluetooth, there seem to be some interferences between the two. One of my beta users reported, that fixes sometimes did not come in continuously when using both at the same time. As BTStack GPS passes on the original timestamp, this will not have an impact on timing accuracy but only results in some poor online display effects.

- Harry

P.S. Please note that the PCX Kiwi Bluetooth does not work with the iPhone! You need the Wifi version or wait for future options.

Hi,

The only BT connector announced to be certified by Apple is the Griffin Cartrip http://www.griffintechnology.com/products/cartrip. I will try to support it as soon as it is available. Any pointer for other devices welcome.

Also, from what I understand, only bluetooth one device can be connected through BTstack at one time... can you run both for iphone with laptimer pro???

Hi Michael,

In general, BT can connect to more than one device at the same time. Please contact the BTStack GPS author for more information on this. The OBD key is available as a Wifi edition. I did not get one into my hands to test / configure. In case there is anyone out there who can support me with testing / adopting this (i. e. has such a device, runs LapTimer, and is willing to go through testing), please contact me at LapTimer at gmx.de.

So looks like the best options for both GPS and OBD 2 is Bad elf for GPS and Griffin Cartrip for Bluetooth is that correct? I think I will wait for these items to become available before I make any more purchases...
The reason why I am interested in two bluetooth devices is to avoid draining the battery too fast. Wifi seems to do that
Is the Bad Elf already updating at > 1hz??? If not when will it be updating at >1Hz
Also, BT Stack GPS will not allow you to run more than one device. roqyGPS will allow one to run more than one bluetooth device

Yes, I'd suggest as both are not yet tested. I'll report in this forum and on the Compatibility page on www.gps-laptimer.de once things change.

And yes, that is a real problem with Wifi (and actually the reason BT was invented).

It would be great to support the ELMCan WiFi module too, as this is one which a few iPhone owners may have as it works with DevToasters REV software...

(I'd personally love to see a bluetooth compatible version to work with some of the cheaper bluetooth interfaces available from DealExtreme too)

Hello,

In case anybody out there has either an OBDLink WLAN or an ElmCan-II WLAN available, and is willing to do some testing, please contact me at LapTimer@gmx.de
