NXT 2.0 Error code: -142016
The Bluetooth does connect. I am not having these issues with any of my other Bluetooth devices running off of the same dongle.
Where do I find the meaning of any other error codes that I may encounter for the NXT?
LEGO's Bluetooth support page has a limited amount of support for Bluetooth errors. It mentions further Bluetooth support can be found in the user guide on:
You may also get in contact with LEGO's customer support.
Your NXT may need to be reset, then the Bluetooth may work. I've found with other devices that sometimes helps. Or maybe you'll need a new NXT. Sadly they are very expensive.
