It does look like there is no MTP support in NCS yet, hopefully it will get added in the near future. Having storage on an embedded device without both the device and the host being able to read/write is not terribly useful.

Thank you Turbo J and Kenneth

Hello,

Seems like this is a limitation of MSC, since when it was invented the only way it was changed was through the OS, so it was never designed out of the box that something else could change the files.

Looks like MTP could be the way to go, but I can't find this is supported in zephyr yet no.

Mobile phones (at least android) solve this problem with MTP. Dunno if there is a good implementation for zephyr available yet.
