Inserting a Single OBD Request into the Poller
Could someone point me to an example of the correct way to insert a single OBD request into the poller? As an example, I’d like to request the VIN—but I only need to do this once, not on a recurring basis. I was previously using |PollSingleRequest|, but it no longer seems to be working as expected. Thank you in advance for your help!

When I "wrote" the vehicle_chevrolet_c6_corvette I found that I didn't need to request the vin -- the BCM announces it no startup. I suspect this is due to all of the modules that are "married" to the vin (e.g. satellite radio and instrument cluster). Craig
Look at ioniq 5 for that specific example! Michael On Mon, 26 May 2025, 04:09 solterra--- via OvmsDev, < ovmsdev@lists.openvehicles.com> wrote:

Notice that I did it 2 different ways. When the car goes into on state it tries a non blocking request. If the user requests the vin from the cli and the vin hasn't populated.. it tries a blocking request. It uses common code to decode the VIN. //.ichEl On Mon, 26 May 2025, 12:15 Michael Geddes, <frog@bunyip.wheelycreek.net> wrote:

Thanks for the pointer—much appreciated. My vehicle has a communications gateway that blocks access to certain ECUs depending on the vehicle state. I’ve noticed that using |PollSingleRequest| has caused some trouble during state transitions, possibly because the ECUs haven’t fully come online yet (e.g., when entering drive mode or starting a charging session). I’ll give the non-blocking request approach a try and explore other options if that doesn’t do the trick. Thanks again! On 5/26/2025 12:28 AM, Michael Geddes wrote:
