I'm having trouble connecting my EZ-B to the software. The EZ-B bluetooth is connected to my computer, but when I try to connect to the software, I get a "could not connect to the EZ-B. Would you like to view the Connection Tutorial?". I ran the firmware update and received this message:
Attempting connection to COM3
Connection Failed: System.IO.IOException: A device attached to the system is not functioning.
at System.IO.Ports.InternalResources.WinIOError(Int32 errorCode, String str)
at System.IO.Ports.SerialStream..ctor(String portName, Int32 baudRate, Parity parity, Int32 dataBits, StopBits stopBits, Int32 readTimeout, Int32 writeTimeout, Handshake handshake, Boolean dtrEnable, Boolean rtsEnable, Boolean discardNull, Byte parityReplace)

Disconnected
I'm running Windows 7 Ultimate 64 bit on a bootcamped Macbook Pro.
I have built-in bluetooth.
Any advice is welcome!

any ideas on how to fix this?
Sarah, almost every connection issue is due to an unusual configuration on the computer. Specifically, not the native microsoft windows bluetooth stack.
Firstly, check this diagnostic procedure: http://www.ez-robot.com/Tutorials/Diagnostics.aspx
If that passes, then feel free to Contact Us to send in your board and i'll personally take a look at it for you
Also, when you attempt to establish a connection from the computer, what do the two LED's on the EZ-B do? There is a little red LED on the bluetooth module, and a blue status LED on the PCB.
the ezb led just flashes (not pulses).
I've tryed windows xp pc bt stack with two types of dongles
and windows 7 lap top with said dongles.
i'm waiting for a new chip form Amy to arrive if i don't have any luck i'll send you
my ez b to look at if thats ok
When the connection fails, they both resume flashing
The drivers for the Broadcom 802.11n Wireless Adapter have a setting called "Bluetooth Collaboration" that is Disabled by default. Enabling this option removes the problem instantly. EZB now works flawlessly. The setting can be found under:
Control Panel > Device Manager > Network Adapters > Broadcom 802.11n Network Adapter (right click and choose "Properties". Under the "Advanced" tab, highlight the setting named "Bluetooth Collaboration", then change it to Enable. Then click OK.
Hope this helps.
Also, is bootcamp a virtual machine? For some reason I thought it was just a way of booting directly into Windows. What Windows version are you using? XP or 7?
