[Ovmsdev] v3 hardware disconnecting from v2 server

Wed Jan 31 13:28:41 HKT 2018

Something weird going on here:

My line 299 of ovms_metrics.cpp is the ending curly brace on OvmsMetrics::InitFloat. A good 20+ lines above DeregisterListener (which starts at line 319).

Can you send me your ovms_metrics.cpp and sdkconfig?

Regards, Mark.
