Hi folks,

I kind of liked having the log level default set to Info earlier, so I can see more of what is going on without having to enable it manually. Went into the menuconfig and changed it, only to find that the module ended up in a reboot loop. Putting the logging back to Warn "fixed" it.

Since this is a classic stack overflow / limited RAM issue, I wonder is there is a recommended order of starting stuff that might work around the problem? What I have is for a scenario where the ovms is "driving" my SyncUp OBDII dongle, which provides a wifi hotspot that the module in turn uses for its internet connection (instead of using the internal modem). Then, I can use the hotspot for other stuff in the car, too.

Here's my system.start event file:

OVMS > vfs cat /store/events/system.start/mystartup
obdii ecu start can3
power ext12v on
wifi mode client gregnet3
# power simcom on
vehicle module TR
server v2 start
metric set v.b.soc 55
OVMS >

(Before you ask, the setting of the soc metric is so that I can see the server is actually talking to the module, when the module's on the bench.)

And here's the crash loop, for what it's worth...

Greg
