Post Bluetooth Problems on an MSI Windows 7 Laptop
I am currently running an MSI laptop with Windows 7 Professional.

I can't seem to connect to the NXT via bluetooth. A direct USB connection works perfectly fine.
I have plugged in the bluetooth adapter and tried to search for it in RobotC. It can't find it. (RobotC doesn't even take the time to search before it tells me that no brick could be found)

I tried going to the Bluetooth manager on the control panel, and it can find the NXT AND connect to it easily, but again when I go into RobotC it still doesn't show up.

My laptop has built in bluetooth so could it be that it's conflicting with the adapter?

I tried it on a windows xp desktop and it worked perfectly.

RobotC has issues with certain Bluetooth adapters, the Dell and Toshiba builtin Bluetooth devices are known to cause issues, they may work but no guarantees.

Have you tried using the Abe Bluetooth dongle that came with the kit?

Also, here are some links to help diagnose bluetooth issues:

There was a Bluetooth debug document on the First FTC site, however I could not find it.

Hope this helps...

Internal bluetooth's never seem to work via the Fantom driver (different from the standard bluetooth configuration). This could be because the internal bluetooth is a Toshiba-stack based controller, which is not supported by Fantom.

I would try using the Device Manager to disable the internal bluetooth on your laptop and only use the USB dongle to try and connect. You should not be using any external bluetooth managers other than the one built into Windows.

Make sure you have the correct driver for RobotC.
You can download them for free from the website:
http://www.robotc.net/download/nxt/
and there is a difference between 32 bit and 64 bit.

I disabled the internal bluetooth from the devices manager. It seems to have helped (the NXT makes the chirping noise when I try to connect now), but when I try to connect to it, it says that the COM port can not be created.

We are having a similar problem, we cannot get out Laptop (Dell XPS M1530, running Windows 7 Ultimate) to connect to the NXT. We can locate it in RobotC but every time we do it fails to connect. We are using the Abe dongle included in the kit, and it worked before, but has stopped working on all our computers (including other laptops/desktops) now in just the past couple days. We do have the internal Bluetooth disabled, which never was an error in the past. If more info is needed about our problem please respond, I can give any information requested for the most part.
Thanks in advance,
Team 67 Eastbots

Attached is last years Bluetooth Connection troubleshooter document. It usually fixes
most issues. Do you have a Windows XP system you can test with?

Hope it helps....
