I've tried the command you sendt.
OVMS# can log crtd /sd/file.crtd 286
Unrecognised command
Ths option crtd seams not to exist.
OVMS# can log ?
list Logging list
start CAN logging start framework
status Logging status
stop Stop logging
OVMS# can log start ?
monitor CAN logging to MONITOR
tcpclient CAN logging as TCP client
tcpserver CAN logging as TCP server
vfs CAN logging to VFS
And yes, I do get the data from the BMS.

No matter what method used, it should never set the RR from the can bus
while fast-charing. In my opinion, better the value set to '' or '-'
than 255.
