[Ovmsdev] Can bus error while read canbus

[didier at ernotte.com]

Hi,
I don't know what changed on my OVMS box, but I am no longer abl to read manually (in the shell) any PID with the "obdii can1 request...". I receive the tranmission failure error. But it used to work fine a couple of days ago. Other commands works great like "re obdii scan start...", so the connection with the OMVS box, communication on the OBD2 port, etc works fine. What could go wrong ? I tried to download the lasted image. Same error.

Here is a session that I did : 

OVMS# re obdii scan start 1 7e4 dd00 de00 -r7ec
