I'm using esp-idf from
https://github.com/espressif/esp-idf.gitThe previous was some months ago on release/v5.2 a36d8bc742 which ran on an ovms unit not connected to a car.
I've just done a compile off v5.3 .. with a series of patches that I've got from Ludovic and some extras from myself.
I've also used the latest mongoose which is annoyingly problematic as they re-did the whole way it was put together making it impossible just to apply patches. I've re-implemented some of the good things they used to have wrt defines and there are a couple of things that ovms team added that would be required. One of those is that the 'certificate' is meant to be a filename and there was a patch to the ovms version that allowed that filename string to be the certificate itself.
