Hi Everyone,

After accidentally finding this site while looking at Roomba reviews on YouTube I decided that I really needed to build a robot. My wife just got the complete kit for me as a birthday present so my children are awaiting the immanent arrival of a robot in our house. The trouble is I cannot get the EZ-B to connect to ARC or do a firmware update. I've trawled the forum and seen similar issues but never an actual fix for the problem, hopefully I've covered all the obvious stuff in my post (sorry it's so long).

So far the steps I've taken are...

I've paired the EZ-B with my laptop (running windows 7). It shows up under Bluetooth devices as linvor. COM6 and COM7 were shown as the ports when it connected

At this point on the EZ-B I have a flashing red light (Bluetooth module) and a solid blue light.

In control panel \ device manager under Bluetooth radio it shows Microsoft Bluetooth Enumerator, Driver provider for this is Microsoft. and Dell Wireless 365 Bluetooth Module, Driver provider Broadcom So I think I'm using the right Bluetooth stack everything looks like DJs tutorial video when I paired the EZ-B, can someone confirm?

Next I opened ARC selected COM6 in the drop-down for connection 0. Pressed Connect. Red light stops flashing briefly and I got this message...

Attempting connection on COM6 Comm Err: The operation has timed out. BbytesToExpect: 1

Received: Disconnected Connection Failed: System.Exception: Controller Not Responding at EZ_B.EZB.Connect(String hostname, String tcpPassword, Int32 baudRate) Disconnected

I went back and read/watched the online support/tutorial. I tried firmware update (I think I need this since device name is linvor and I have a flashing blue not 'pulsating' when it's not connected to bluetooth), got similar message.

At his point I went back to online support again and tried the 'hardware diagnostic', the board passed resistance and voltage tests.

So at this point I think I've exhausted all the resources currently on the website. Any help you can give me to get this up and running would be greatly appreciated. Looks like it'll be a great bit of kit if I can ever get connected!
