Chat Example doesn't work for me about ios HOT 2 CLOSED

Yes, I am having this same problem. It connects fine, discovers the correct services, but didUpdateValueForCharacteristic is never called. For some reason, the BLEArduino app I downloaded from the Apple store DOES work: it shows me analog data updates from Firmata, but the Chat app doesn't work.

Here's what I'm using (latest checkouts for everything):

Firmata_BLEMini.ino - https://github.com/RedBearLab/BLEMini/tree/master/BLEArduinoApp/Firmata_BLEMini
Biscuit 1.3: https://github.com/RedBearLab/Biscuit/blob/master/release/Biscuit-UART_20130912.bin
iPad Retina, iOS 7.1

Could the UUIDs for the RX/TX have changed? Could you please post the source for the BLEArudino app in the Apple store?

Nevermind, I found the problem. The Firmata doesn't report analog inputs by default. You have to turn them on in the .ino file. Patch here:
