[Ovmsdev] Can bus error while read canbus

 Hi,
Is there a way to manually start a OBD Poller or what is the condition for not having an active Poller ?

  Hi Michael,
It seems like there is no poller.

  Didier,

 the error message tells the now separated poller isn't started and also cannot be started for the request.

 Check "poller status":

 OVMS# poller status
 Poller on Can1
   List: active
   State: 0
   Last Request: 1s (ticks)
 Time between polling ticks: 1000ms
 Last Poll Received: 0s (ticks) ago
 Poll Queue Length: 0
 OBD polling is Resumed

 Enable logging for tag "vehicle-poll" and issue "poller trace on" or possibly "poller trace all" if that doesn't show the cause.

 Regards,
 Michael

 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
