Just got my H9 today and I can't get it to work with the iOS app.
It connected via USB to my Mac just fine and I was able to update the pedal's software and redeem a free algorithm, but for whatever reason I can't make it work on my iPhone.
I've read a lot of people having issues with Bluetooth, but mine seems to pair fine. Both blue LEDs are lit. However, when I launch the app (or it launches itself) the "paired" LED goes out and flickers and the app keeps telling me it's disconnected and I get stuck in this loop of the app relaunching over and over again even when I go to the home screen and quit the app.
I tried deleting the app to see if the Bluetooth LEDs would flicker at all without H9 Control launching, and they don't. Solid blue LEDs. Reinstalled H9 Control…no such luck.
I have the latest version of iOS (7.1) on my iPhone 4S and the latest firmware for the H9, but it might be worth mentioning that I tried this before updating the firmware and had the same exact issue. Please help!
