[Ovmsdev] Trying to get a new car in, CRTD, CANbus and all

One comment:

The new format CRTD produced by OVMS includes bus# prefix. So the records look like ‘1R11’ or ‘2R11’ (for bus #1 and bus #2, respectively). SavvyCAN currently supports only the old format ‘R11’ CRTD. If you want to load these into SavvyCAN, you will need to modify the CRTD log file.

There is currently experimental support for SavvyCAN server mode in the latest bleeding edge OVMS:

OVMS# can log start tcpserver gvret-b :23

Then put in the wifi IP address of the OVMS into the SavvyCAN server connection, and you should start to see live data from OVMS. This is experimental, and still a work-in-progress, but basic functionality is working.

Regards, Mark.
