Freematics Forum

Hi,

I am a happy owner of 3 Freematics One+ Traccar Editions.

After few hickups, most of what I aimed to achiev is running great (traccar intergration)

One of the remaining Problems is the fakt, that sending of OBD-data is noch working reliably.

When I hook up the modul, it is recognizing OBD and the modul is sending the OBD-data (rpm etc.) as it should and it is visible in traccar. So as far I can tell, the module is working as it should.
My car is a 2015 skoda and has a always-on OBD connector, so I use a low MOTION_THRESHOLD to wakeup the modul. I have RESET_AFTER_WAKEUP also set to "1".
The Problem seems to be, that after the "wakeup/reset" the OBD is not reinitialized. In the code it seems that STATE_OBD_READY is never set back to STATE_WORKING.

When I disconnect the modul and reconnect it, OBD is working great again.

This is all just guesses from my side, because I actualy can´t do code. I try to read it and think I understand few things, but no-where near enough to try to fix this issue.

If there is anythink I can help with (deeper debug) just let me know.

When you saw OBD is not properly reinitialized, did all subsequent attempts fail?

yes, I reviewed the Traccar entries, there is never more then few hours of OBD data.

example:

OBD Data on 2022-05-06 9:14 till 9:37
OBD Data on 2022-05-06 20:36 till 20:37
OBD Data on 2022-05-16 9:01 till 9:50
OBD Data on 2022-05-17 18:54 till 20:42

and so on.

every time I disconnect and reconnect to OBD I get OBD data for the duration of the trip, after the Modul goes to standby and awakes again, nothing and I drive everyday, so there are multiple standy/awake cykles.


The only way to get OBD data again is to disconnect and reconnect the module to OBD... well also another, when I flash the modul, it reinitialize properly and get OBD without reconnecting. So it seems the standby/awake cykle is causing the issue.

I was also thinking that with the wakeup/reset the OBD interface of the car could be still "offline" and generate faults and the MAX_OBD_ERRORS could trigger OBD not to try again. But as I use the motionsensors to wakeup, somtimes I can hear the "beep" of wakingup when I am well on my way and the OBD interface of the car is certanly online.

Try adding following line after device waking up. I've also committed this change to github. Let me know if it solves your problem.

I have implemented the changes and it seems to work, but I had very limited "standby"-time to try.
I will have final confirmation in a few days (Weekends I usualy dont drive)

Thanks for the fast fix, I will keep you updated.
