Tried to repeat this, but not having much success. Here is my car module, with network still up:

OVMS# boot status
Last boot was 262355 second(s) ago

I did manage to catch one network related crash after repeatedly disconnecting and reconnecting the cellular antenna. This was:

My for_v3.3 branch does include the preliminary changes to support the wifi at 20MHz bandwidth, and perhaps those could be affecting things. I do notice that if I ‘power wifi off’, then ‘wifi mode client’, it can connect to the station, but not get an IP address. I’ve just tried to merge in the latest fixes to that, and rebuilt a release. I will continue to test with that.

Regards, Mark.

I just tried switching to for-v3.3 in my car module after tests on my desk module were OK, and I've run into the very same problem with for-v3.3. So the issue isn't related to esp-idf.

The network only occasionally starts normally, but even then all connectivity is lost after a couple of minutes.

The stale connection watchdog in server-v2 triggers a network restart, but that also doesn't seem to succeed:

I need my car now, so will switch back to master for now.

Mark, if you've got specific debug logs I should fetch on the next try, tell me.

I just updated to 3.2.016-68-g8e10c6b7 and still get the network hang immediately after booting and logging into the web gui.

But I see now my problem is likely that I'm not using the right esp-idf (duh). Is there a way I can have master build using ~/esp/esp-idf and have for-v3.3 use a different path?)
