Soko,

polling may keep the car awake, that's also an issue on the Kia e-Niro IIRC.

Changing the PollState can only affect the car indirectly via the changed polls. Maybe you could add your code & a log?

Regarding the poll replies stopping, is that also reflected in a CAN log? Maybe the OBD gateway throttles if it sees too many requests? (Hopefully not…)

If the gateway does throttling: do you login to the OBD as a "tester" and keep the session active by periodically sending the "tester present" frame?

Regards,
Michael

Heya again,

I'm trying to develop a detection for when the car is off/locked but I'm encountering a weird phenomena:

• Car is shut down and locked
• OVMS connected
• CAN poll for voltage (only one poll value active) with 30 secs fails with error (so far nothing weird)
• Unlock the car via car-key remote
• Poll succeeds and I'm switching from PollState=0 to PollState=1 where I poll every 2 secs
• Lock the car via car-key remote
• After 1 hour the polls still work and the car is active

Is something like this known from other vehicles? So basically my car never shuts down :(

Another secondary weird thing:
When increasing the time to 5 secs for PollState=1 the polls get no reply and after 20 secs I swap back to PollState=0.
BUT the second the PollState changes the car replies again...
Even more weirdness: When PollState=1 time is 10 secs and I swap back to Pollstate=0 after 40 secs the same thing happens! Immediately I swap to PollState=0 the car replies again.
As if the PollState switching somehow wakes the car up??!

Any ideas?

Soko
