What is the problem?
I am unable to connect to a CR-30 with Octoprint 4 Android using a Nuu Mobile R1.
What did you already try to solve it?
Confirmed that the phone can OTG and charge using a flash drive and Y-cable and tried it with just the phone connected to the printer.
Have you tried running in safe mode?
Yes.
Did running in safe mode solve the problem?
No.
