This made me think I had a Bluetooth problem last night. My fresh ezb before software update said Linvor. This made me think the netbook couldn't pair with ezb but turns out it was just the Bluetooth default name. I wanted to share this so others didn't think they had a Bluetooth problem when everything is fine

If its a brand new ezb, the Bluetooth will show as linvor. Once updated with firmware, it will be EZ-Robot.
Here is the tutorial page for adding Bluetooth: http://www.ez-robot.com/Tutorials/Default.aspx?id=5
I'm trying to connect to ez robot with bluetooth on Windows 8 and the device linvor shows as offline and I can't connect.
Help.
Thanks
If it's already paired you don't need to bother connecting to it in Windows, just connect via ARC or the SDK.
If you are pairing it, make sure it's powered up, red light flashing, windows should see it.
Again the linvor bluetooth device shows as offline in the WINDOWS 8 bluetooth settings. I must be missing something? Should the device show as offline?

Is the EZ-B powered and the red light on the bluetooth module flashing?
If COM3 is the correct port it's timing out which suggests it's either not the native stack being used, that the EZ-B isn't powered up or it is too far away.
To confirm the port number;
1. Open desktop
2. Open a windows explorer window
3. Type in the path Control Panel\All Control Panel Items\Devices and Printers
4. Right click on the EZ-Robot/Linvor
5. Select Properties
6. Click on the Hardware tab
7. Note the com port number after "Standard Serial over Bluetooth Link"
It should say the device is offline, that is correct.
It is the native WINDOWS 8 stack. Does EZ Robot work with WINDOWS 8?
Is the EZ-B powered and the red light on the bluetooth module flashing?
Yes powered and the red light on the bluetooth module is flashing.
If COM3 is the correct port it's timing out which suggests it's either not the native stack being used, that the EZ-B isn't powered up or it is too far away.

Thanks. It's on com port 4. See debug message below. I tried 3 & 4 before.

When you add the EZ-B it will add 2 COM ports, generally it is the lower of the 2 (i.e. if it added COM10 and COM11 it would be COM10). The method I described above is not always 100% accurate (blame Microsoft) though so it's always best to try both ports unless you connect first time.
Everything should work and it should connect. Short of unpairing the EZ-B, rebooting and pairing it again I don't know what else to suggest. If using the native stack, correct com port, the EZ-B is in range and powered with the bluetooth light flashing it has no reason not to connect.
I just tried an old laptop running Windows 7 and still can't update the firmware.
This is what I got this time.

Got the Ez-Robot Complet kit and also use windows 8 as the operating system and I'm having the same difficulty as the friend reported above.
I followed all the steps in the tutorial but the Bluetooth Devices "linvor" appears as OFFLINE and upgrade program can not establish a connection showing the same error mentioned by RCWilly friend.
I use a Sony Vaio Ultrabook with bluetooth and windows 8 as native OS could help me!
Thank you!

It will show as offline, that is normal.
