@TheoL there are two pull requests adding support for newer versions.
One is guaranteed to break again.
One should not break in the future, but will instead break all existing sketches.
I’m sure a third option would be welcome if you write the code and submit.
No, it does not recover.
The Problem is not easy to debug. I now want to build a serial gateway. With that, I am more flexible to test. Maybe to run MySensors on a second raspberry pi with a standard Home Assistant HASS-Os image. Or I check the MySensors network with MyController.
At this moment i run the whole system on 64 Bit raspbian, with HA in docker, which is a little bit experimental and i had to fix some lines in the ethernet gateway to compile it for 64 bit. So this is experimental, too.
