[Ovmsdev] Can bus error while read canbus

Sat Nov 2 21:44:06 HKT 2024

 Since the can1 is active at boot up time I don't even use this command. I mostly use the PID scanner, the shell with obdii command, and the logger/vfs command to capture log. I have programmed everything I need to query PID in javascript using web plugin.I can definitively give a hand testing the vehicle implementation with ducktape.

 Ahh.. yes.  
I've had a look and I believe I've got it. I'll just need to make sure that the "can can? listen" and "can can? active"  commands go through thepoller so that it starts up the polling thread (with a bit of conditional compilation for the where the poller is not compiled in).
I'm assuming that you do, in fact, call these commands?
On a side note, I've been working on a whole bunch of stuff to allow users to program a whole vehicle implementation with duktape and commands... so if somebody were interested in testing that (the bit that I'm struggling to find time for at the moment) I'd be happy for the help.

 Ok, maybe I found something. There is no vehicle selected in the config because I am not using the OVMS box to monitor continously my car, I simply do spot check and manual queries. But if I select a car and deselect it, the poller started....

  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
