What steps will reproduce the problem? 1. Installed latest ios8 compatible BTstack and BTstack GPS 2. Started BTstack GPS, started my GPS device: GT-750F 3. Started connection process

What is the expected output? What do you see instead? Expected: BTstack GPS to pair with GT-750F Instead: Connection process continues indefinitely

What version of the product are you using? On what operating system? BTstack 1.0-3; BTstack GPS 2.0; IOS8.4; iPad 3; Canmore GT-750F

Please attach a package log, as described here: http://btstack.uservoice.com/knowledgebase/articles/69548-how-to-get- btstack-communication-log

Thanks! Sjoerd.

Hi Sjoerd

Thanks for the report and the log file. There's clearly something wrong. BTstack reports an event twice and BTstack GPS doesn't handle that well. I'll try to fix both in the next week.

(the baud rate of the GPS is not related to the baud rate that BTstack uses to talk to the Bluetooth chipset. In fact, BTstack uses the max 4 mbps or so, the same way the iOS stack does it)

Hi Matthias,

btstack_1.0-4 seems to have solved the issue. I now have a steady connection, and the GPS position is forwarded to other applications. Thanks for you quick response!

Cheers, Sjoerd.
