    My environment:

    • Mid 2012 MacBook Air
    • Mac OS X 10.8.4
    • Xcode 4.6.3
    • Cirago BTA8000
    • ...and TI CC2541 SensorTag (with fresh CR2032 battery)
    Here is the datesheet of cr2032

    I have downloaded and installed the SensorTag iOS source code examples and I am attempting to build and run the SensorTagEX example app.

    Starting from a fresh Mac restart, I launched Xcode, opened the SensorTagEX project and successfully built and ran the app in the iOS 6.1 Simulator by clicking on Xcode's Run button. Then I stopped the app in Xcode and quit the simulator to read the source code files. Then I clicked Xcode's Run button once again but got different results.

    The app appears to hang after detecting the SensorTag device. In the Xcode console, I see:

    2013-07-23 14:44:07.455 SensorTagEX[1776:c07] Found a BLE Device :
    <CBConcretePeripheral: 0x9553db0 UUID = <CFUUID 0x955f830> 924D7A39-
    DEC2- 2C4B-3E0E-AD485CCFD45C, Name = "TI BLE Sensor Tag",
    IsConnected = NO>

    2013-07-23 14:44:07.457 SensorTagEX[1776:c07] Found a BLE Device :
    <CBConcretePeripheral: 0x9553db0 UUID = <CFUUID 0x955f830> 924D7A39-
    DEC2-2C4B-3E0E-AD485CCFD45C, Name = "TI BLE Sensor Tag", IsConnected =

    and then nothing else.

    If I reboot the Mac and relaunch Xcode, as before, I can run the SensorTagEX app once successfully, then subsequent runs appear to hang, as before.

    The SensorTag board has a sticker that says "1.3 1252"

    Any help or guidance will be much appreciated.
