I have two Pis, one is running with Debian Version 9.3 and this is working fine. The other is working with Debian Version 9.4 and in order for it to work I have to have run IDLE3 in the sudo mode launched from a terminal window.
I know in the new system that IDLE2 was removed from the Programming menu, but have there been other changes as well?
The older system has had all sorts of GPIO libraries added, where as the new system has very little on it. Is it possible that the old system has been loaded with some sort of privileges that I have forgotten about? If so how could these be restored?
When the new system is refusing to connect without the sudo running of IDLE3 I get this error message:-
Code: Select all
ERROR:pygatt.backends.gatttool.gatttool:Unexpected error when scanning: Set scan parameters failed: Operation not permitted
