The last piece of the puzzle falls into place.

OVMS# config set auto ota yes
OVMS# config set ota auto.hour 2

Module will wake up sometime between 2am and 3am, and if wifi is available it will check the available server version (according to OTA tag and server url). If the server has a later version, the module will download and flash that new version then reboot into it.

I’ve also brought in the strverscmp function for GNU library, which is generally useful for comparing versions.

Enjoy.

Regards, Mark.
