Bluetooth Discovery Finds Linvor , Ezb Bt Default Name

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;) - Josh S

Help.

Thanks

Are you trying to pair it or are you trying to connect to it?

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.

I am/was following the tutorial, but the process for adding a device in WINDOWS 8 is different from WINDOWS 7. The device (linvor) appears to be paired, but there is no option to select a com port. When attempting to update the firmware neither com 3 or 4 works.

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?

Here is the debug message I get when trying to update the firmware.

Is it the native bluetooth stack?
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.

Yes it works on Windows 8, I believe DJ Sures uses Windows 8 himself. I run it on both Windows 7 and Windows 8 depending on which robot/project.

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 appreciate your help Rich.

I just tried an old laptop running Windows 7 and still can't update the firmware. :(

This is what I got this time.

Well I guess I'm stuck using Mindstorms...

Hello to all!

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!

Ensure you select COM4 in the firmware update program and try to connect. If it fails (give it a few tries) post the debug message.

It will show as offline, that is normal.
