hi there guys i have a problem regarding my ez-b i recently couldnt have much time to build robots and such so i needed to stop my projects when i came back my computer couldnt find the board from same com my board is blinking blue bluetooth device blinking red help me what should i do how can i fix this?
What does the debug say in ARC?
And as @dkennyken said, check to make sure it's still paired with the PC.
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 have 2 computers one is a mac other PC my mac's sees the ez-robot but my PC doesnt i think i have a pairing problem as you guys said how can i make my computer see my ez-b?

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!
It sounds like it is establishing a connection but then almost immediately dropping the connection. This could be a few things...
Check it's set up on the PC correctly and that you are using the native windows BT stack. Also, it appears that Windows 8.1 can cause issues with the BT, have you updated to 8.1 recently?
Check your power source. A low battery or a high demand on the EZ-B may cause the connection to drop out. Try disconnecting everything from the EZ-B and connecting a decent power supply to it (better yet, connect an AC/DC power supply for example from an old router, switch, portable CD player etc. (anything from 5v to 17v will do)
and i am using windows 8 and recently updated this is the battery i am using http://www.hobbyking.com/hobbyking/store/__17825__Turnigy_2650mAh_3S_1C_LLF_Tx_Pack_Futaba_JR_USA_Warehouse_.html
also tried using a AC 15V power supply
can it be anything to do with ez-board itself? or do i just need another bluetooth device
If your bluetooth unit is actually turning off, when a connection is attempted then it may be a defective unit.
