Try removing the Bluetooth device and then re-discover it.

I have tryed that. And I tryed 2 laptops

Still get the thing. This sucks. My 1st ez-b had a bad regulator. Killed the ez-b. And this one just worked for a few days... any one have this much bad luck? I can't spend this much every few days. Man...

What lights are flashing when you apply power? Disconnect anything you have connected. There's no reason an EZ-B should just "break". Electrical components only break when they are shorted or get too hot. What do you have connected to it? What power source are you using? Etc

The computer isn't seeing the EZ-B.

Follow the diagnostics process detailed in the tutorials. If that still does not help then use the Contact Us page to get in touch with EZ-Robots, explain the problem and they should be able to give you some advice.

It's rare that the EZ-Bs are bad however like any electronics they wont all be perfect.

When the same person is receiving multiple bad boards (or anything for that matter) it always makes me think that it could be user error more than faulty stock, you would be very unlucky to receive two faulty boards. The failure rate on these boards is extremely low.

I have nothing hooked up to it. Both lights flash. The blue is pulsing. And the red will flash till I try to connect to it with blue tooth. Then the light will stay on. For a few sec. The flash. And says all that was in my 1st post... I try and double check everything before I ever apply power.

And my 1st kit had a broken sorvo from getting shoved into the box it comes in. But I don't care about that to much. It still works. Just broke off the the screw holes and I can see the gears. What I do care about is how this one. Has been working for a few days. Then I just cant connect.
