[Ovmsdev] 3.0.991

[Michael Balzer]

Steve,

the IP address is fixed to 192.168.4.1 for the AP.

Zeroconf / mDNS allows to address the module using the name "<moduleid>.local", but is not supported on all systems. It should work on iOS, but I can't test
that. It doesn't work on Android 7, so is not usable as a general solution.

Thanks for the crash report. It's not related to the esp-idf version. It occurs frequently if you're running low on memory (i.e. with many metrics and/or
multiple web clients open in parallel), plus there's currently a race condition between metrics and event transfers. I'm already working on a solution for both.

Regards,
Michael
