I managed to get another WiFi related crash... As before, this was an attempt to turn it off right after the system starts (just before the first scan completed with the usual "incorrect scan type" message), but doing so at that time doesn't always seem to cause the crash. This is on the old 2.1 environment, if that matters. Greg OVMS > wifi mode off Stopping wifi station...
