Got my EZB kit today and I'm very excited. All I want to do for now is see a servo move. 
I've followed the setup instructions. Upgraded the firmware. And now I'm following the steps to just get a standard horizontal servo moving.
The problem is I can only connect on COM3. There is a COM4 option but it won't ever connect to that one.
COM3 will connect but as soon as I start to assign the servo it loses connection.
I'm a Mac/Apple guy using a borrowed PC to try this out. It's running Windows 7 Home premium. It's got 8GB of RAM and has a 2.5GHZ intel i5-2450m CPU. The bluetooth installer looked the same as the video.
The only differences I've noticed from the video are it won't connect to the second port at all and in the tutorial it says you'll find ARC in the Add Device menu but it was called 'livnor' instead. Also, when going to update the firmware it would not connect on COM4, the second option as DJ mentions in the tutorial. It would say the write timed out. But with COM3 (option 1) it connected perfectly.
Any thoughts as to why the connection keeps dropping? Thanks! As I said I just want to see a servo move from my control!
You might want to consider either using the power supply offered in the Store page or build you one with a higher capacity. The AA batteries don't really have the ability to provide high current demand that your servos evidently need.
Hi TB, Isn't the world of Robotics exciting and frustrating at the same time. I remember how excited my son Austin, brother Dean and I were to see the first servo move via the EZB. Issues I had similar to yours were mainly related to low voltage. If I started with brand new batteries and the voltage dropped to 6 volts or less I would loose connection. Even quality batteries hooked up through the kits battery pack never seemed to last long. Today we use a 11.1 2 amp lipo with a pc fan blowing over the board and in the hundreds of times Bob starts up we've never had a problem. The other thing you need to look at is the bluetooth adapter on the board itself. Whilst everything like the pins and processor are soldered in solid, the adapter saddles on top and is a bit flimsy. Mine wobbled up and down a bit and with it the connection. I used a rubber band to hold it in position and bingo - no problems since.
Anyway, good luck, it's a great and rewarding journey and there is a lot of help at this site.
Cheers

You should be able to move many servos at a time with the battery pack. All 6 that are included in the kit. Can you do these two things for me please...
Do the voltage regulators get hot when it is connected to ARC with no servos connected?
What happens if you do not connect servos to the EZ-B - but you set the controls to move servos on D1, D2. I'm asking if you can add controls to move servos that aren't actually connected. Have nothing connected to the EZ-B, and merely add a servo Control, Select Port D1, and move it. Does it still disconnect?
