[Ovmsdev] Server v2 hang / crash / ?

Mon Mar 19 06:54:53 HKT 2018

Greg & Steve,

that's again mDNS. My module has now, without mDNS, been running for over four hours with many reconnects and no problems at all.

There is an mDNS fix upstream esp-idf, but I don't think that is related to our issue: c68fd9d54535f8123b2f63d1061114eff9f77c1b

We need to update esp-idf, but it's too late now for the first factory image. Better just exclude mDNS for now.

I've pushed my workaround for the AP mode startup in OvmsServerV2::NetUp() -- it works, but as Mark said, we certainly need to revise the network init procedures.

I'm off for today. Besides the mDNS issue I think we've got a very usable first release.

Regards,
Michael
