I am still suffering from unexpected disconnects, but tolerable. but 2.) when bluez disconnects it immediately deletes var/lib/bluetooth/ aa:dd:aa:pp:tt:ee:rr/ "paired-peroiferal-mac" and var/lib/bluetooth/ aa:dd:aa:pp:tt:ee:rr/cache/ "paired-peroiferal-mac" all the time! Which leads to make the central forget the paired device completely and makes it unable to reconnect. I cannnot avoid this absolutely strange behaviour, exept to make the folders undeleteable and restart the bluetooth-service everytime this happens. Du you have an idea why bluez should delete the files/folders? please help- Peter
