Hi, afraid I'm on here asking for help again since I'm still having issues
When I got my first EZ-B this happened...
my original connection issue
I just got the replacement in the post. Powered it up and ... no blue light. The little red one flashes and it still connected to bluetooth on the laptop. But again I can't get it to connect to ARC or the firmware update.
Again I've followed all the steps in my first post with the same results. Am I doing something wrong?

Been through the diagnostic resistance and voltage as in the video both check out ok
There is no voltage to the Blue LED as far as I can tell.
I'll have a good look over the board tomorrow with fresh eyes
I've found an old router supply (thanks for the tip @rich), plugged it in and the blue LED is now working. I'll have a good look at the battery pack, it's showing 9v+ but there must be something wrong with it maybe the screw terminal isn't making a good connection, that can wait for another day.
Most concerning is that I'm still having the connection problem. Latest debug report from the firmware updater...

So basically the same symptoms as my first board. No response from the EZ-B. Visually everything looks ok on the chip and the solder joints to the chip all look ok to my untrained eye. What am I doing wrong?
Incidentally the laptop is a Dell Inspiron 1110 11z, Windows 7, 64-bit. It's about a foot away from the EZ-B
From the looks of the debug message the PC isn't listening to the EZ-B. It could be the bluetooth dongle on the PC but it's more likely to be the drivers Dell package with their PCs. I'm always a little hesitant to advise it since it may cause issues elsewhere with other hardware/software (although rare) but uninstalling any Dell bluetooth software and drivers and reinstalling the device with the Microsoft bluetooth stack should hopefully solve the connection issue.
Before doing that, is it possible to check it on a different PC with a bluetooth dongle?
Not sure if it help you to help me but in device manager under Bluetooth Radios I have...
Dell wireless 365 Bluetooth module, Manufacturer: Broadcom, with Broadcom driver, Location Port_#0003.Hub_#0008
Microsoft Bluetooth Enumerator, Manufacturer: Microsoft, Location: on Dell Wireless 365 Bluetooth Module
Both report device working properly
I'll pop over to my Dads when I get a chance and check out with his pc and USB Bluetooth dongle. If it works I'll disable the onboard Bluetooth on my laptop and borrow his usb dongle to try.
"Which Bluetooth host controllers does Windows support?
With Windows, a Bluetooth radio can be packaged as an external dongle or embedded inside a computer but it must be connected to one of the computer's USB ports. The Bluetooth stack that is included with Windows 7 and Windows Vista does not support Bluetooth radio connections over PCI, I2C, serial, Secure Digital I/O (SDIO), CompactFlash, or PC Card interfaces. "
Unless I'm reading this wrong it means that unless I plug in a USB BT dongle to my laptop and disable the onboard BT module it's never going to be using the windows stack, which would explain a few things.

Have I got another defective board?
If it hasn't been re-paired, re-pair it. Go to your devices and printers. Right click on the EZ-B (or Linvor) and check which COM port it uses (in the Hardware tab).
One of my EZ-Bs is COM17 and the other EZ-B COM18, a high number is not always an indication of a problem. Neither is having COM ports that are not sequential.
If you still struggle, I can always take a look at it if you have TeamViewer installed. At least that will ensure it's not a configuration problem on the PC side of things. Just say the word and we can arrange a time suitable.
