Hi chewitt, Obviously it would be easier to manually enter the credentials, the problem arises if the device you are programming comes from someone who then has problems in entering data such as password, DNS, etc. again, or even just because there are so many SSIDs saved.
In the folder "connman" I found various folders named with a code that refers to the various SSID with inside the files "settings" where the credentials are saved then through SHH (Filezilla) I imported the various folders.
After a new installation of Libreelec I connected the device to the internet with my network and then via SHH I sent the various SSID folders previously saved with the "settings" files inside in the "connman" folder. Now when the device at boot no longer finds my network but finds one of the SSIDs in the folders with "AutoConnect=true" present in the "settings" file should connect automatically. Right? Or should I do something else?
EDIT: I did a test with an other device downgrading from LE 11.3 to LE 10.4 and as a description above I reinserted the various SSID folders previously saved in the "connman" folder of the new LE 10.4 .
Everything seems to be working. I repeat it seems. I just noticed that the entry "Frequency=" in the "settings" file is changed by itself from "Frequency=12345" to "Frequency=0".
