# Ubuntu – Logitech K380 bluetooth keyboard – make function keys default

bluetoothfunction keyskeyboardlogitech

There is a software for Windows called "Logitech Options" which can switch media keys to function keys, but this setting is not remembered in keyboard. There are similar cases with other logitech keyboards already with solutions:

But neither seems to work for K380. Has anyone figured out solution for this keyboard? It probably needs capturing communication between keyboard and Windows software, but it's quite complicated.

I did the same steps as Mario to get sequence for k380. The code is same as Mario's, but with the sequence for k380 keyboard and k380 device ID. It outputs write: 0 were written instead of 7 on my computer, but it works anyway.
const char k380_seq_fkeys_on[]  = {0x10, 0xff, 0x0b, 0x1e, 0x00, 0x00, 0x00};
