This might sound a silly question but is the bluetooth linked to the EZ-B when you look in bluetooth devices on your computer?

Does the red light stop flashing at all when you try to connect? What does the debug say in ARC?

And as @dkennyken said, check to make sure it's still paired with the PC.

If no devices are showing up you need to set bluetooth setting to automatic as it's probably disabled.

Go into computer management and click services and then bluetooth supporting service and right click--> enable. Wait for it to enable and then right click again --> properties and then select start type to automatic.

Then just click start and check in bluetooth devices to see if it's linked, or add it again?

I would first try to cycle power on the board and see if that helps.

From what you are describing it sounds like the bluetooth module is making a wireless connection but it may not be making a good electrical connection with the EZ-B chip.

A couple things to try are:

-Push down on the chip and make sure it's making a good connection with the chip socket -Pull the bluetooth module a little bit out of it's socket and push it back down again

Both of these actions "reseat" the physical connections to allow for better electrical contact

Let us know if these help, thx!:)

i tried doing them bluetooth light blinks when i connect power it keeps blinking for a while than it stops is that normal?

As long as proper power is applied to the EZ-B, the bluetooth LED should flash until a connection is established at which time the LED stops flashing and stays on steady.
