If you have questions about using Ubertooth the first place to look is the FAQ.
Many Ubertooth developers and users are available in the #ubertooth channel on Discord. Please remember that we work across many timezones and you may need to wait some time for a response to your question.
We use the GitHub issue tracker to log Ubertooth bugs. If the bug has previously been reported then adding detail is often helpful. If you believe that you have found a new bug, then please create a new issue and describe the bug in as much detail as possible.
When logging issues it is helpful for us to know the following:
Operating system and hardware (i.e. ARM, x86, etc) if known
Which command you were using
Any other details that may help us to reproduce the bug
