Hi,
I tried everything:
I downloaded wheezy isos, Jessie.... with GUI, no GUI and then I installed by myself..... solid-run isos and armbian isos....
just clean system... burn the iso in a sdcard and run the system....
if it has already GUI I install blueman and test bluetooth and wifi.... perfect. If doesn't have gui then I install one (I tried xfce and mate), then blueman and test bluetooth and wifi.... perfect.
then 'apt-get update && apt-get upgrade' and bluetooth stops working
Any reason for that and any tip?
