Yes, I can verify. The red flight flashes and the blue light light pulses.

I'm sorry, when I say the lowest, I'm talking about the lowest number, not the lowest position on the screen.

Anyway, I've tried to connect to COM3 as well as to COM5

EZB 0: EZB 1: EZB 2: EZB 3: EZB 4: TCP Server stopped TCP Server stopped TCP Server stopped TCP Server stopped TCP Server stopped Attempting connection on COM3 Comm Err: ????? ???????? ???????? ???????. (time out) BbytesToExpect: 1

Received: Disconnected Connection Failed: System.Exception: Controller Not Responding ? EZ_B.EZB.Connect(String hostname, String tcpPassword, Int32 baudRate) Disconnected Attempting connection on COM5 Connection Failed: System.TimeoutException: ????? ???????? ???????? ?????? ???????. (time out) ? System.IO.Ports.SerialStream.Write(Byte[] array, Int32 offset, Int32 count, Int32 timeout) ? System.IO.Ports.SerialPort.Write(Byte[] buffer, Int32 offset, Int32 count) ? EZ_B.EZB.Connect(String hostname, String tcpPassword, Int32 baudRate) Disconnected

That tripped me up too, is it the lowest port number or the lowest on the screen ?

It's the lowest port of the two which are added when the EZ-B is paired with the PC.

Click Start --> Devices and Printers

Right click on the EZ-B --> Properties --> Services

Both of mine only show the one COM port which is the one to connect to. If it shows 2 it's the lower of the 2 (i.e. if it shows COM10 and COM11 choose COM10)

Thanks Rich

Check if you are using the Microsoft standard bluetooth drivers You have an odd looking bluetooth device in your system tray. I would delete all Bluetooth devices and Drivers and start again with just the EZ-B. It looks like you have a bluetooth dongle device plugged in does your laptop not have BT built in? unusual nowadays it maybe a conflict

Its unlikely to be a language issue as others have been succesful in Russia

Just remember that if your computer/laptop device has bluetooth built-in it will be a class two device that may be capable of up to 10 meters, (33 feet) of communication distance.

We have tried to connect from three different laptops. Unfortunately, still getting the same error. I'd like ask you, maybe any of you could connect to my laptop remotely and try to help. It was supposed to be a present for my son, who actually has found ez-robot web-site. He really wants ez-robot work.

my ez-b is doing the same thing now it was working fine, then when i tried to connect this came up.
