Michael, (taking this back to the list, as other developers may have helpful ideas or suggestions) from a first check, your new patch (PR #1008) won't help for vehicles that don't use the poller, like the generic DBC vehicle or the Fiat 500 (plus possibly non-public third party vehicles). As the poller is normally compiled in, these would need a run time switch to re-enable the vehicle task, or more suitably default into that configuration and switch to the poller task only when the poller gets initialized. How about moving the task back into the vehicle class, but keeping your task message extensions while doing so, and adding a way for the poller to hook into the task? The dedicated vehicle task is an essential part of the vehicle framework, but I do remember some occasions where a general way to pass custom messages to the vehicle task would have been helpful to use the task for more than CAN processing. If the poller shall become avaible as a separate service that can be used without any vehicle instance (currently not a defined use case), the construct of a CAN processor task that can be extended for custom messages (or a message processor task that can subscribe to CAN frames) could be factored out into a dedicated class or template. The poller could then create his own instance of that class, if it cannot hook into an existing one. Btw, in case you're not aware of this, FreeRTOS also provides queue sets (https://www.freertos.org/RTOS-queue-sets.html) We haven't used them in the OVMS yet, but they could be useful, especially if message unions become large or tasks shall be able to dynamically subscribe to different message sources.

Duktape Vehicle
by Michael Geddes 06 Oct '24

06 Oct '24

In a recent conversation with Mark we were talking about utilising Duktape more for perhaps even vehicle implementations. I'm wondering if a better approach is to allow any vehicle to be extended via hooks in the base vehicle class or would it be better to have a duktape vehicle that could be extended. There would necessarily be many bits to the puzzle. For example I have a class that allows us to know when blips to the 12V battery line might mean that somebody is interacting with the car so we should start polling the bus.. Should we put this (with a duktape interface) at the vehicle.h level? //.ichael

Access to a diagnostic session with private access
by didier＠ernotte.com 01 Oct '24

01 Oct '24

Hi, I need to put a ECU into diag mode and access private data in a secured session.I am supposed to send "10 03", then "27 03", receive a seed, and send the private key with "27 04".This is working fine with the terminal in CarScanner mobile app connected to a BT dongle, but when I try to use the OVMS box, the "10 03" is ok, but "27 03" return a serviceNotSupportedInActiveSessionerror. It is possible to start a secured / private session with the OVMS box ? Didier

Pull Request for new vehicle
by solterra＠kezarnet.com 30 Sep '24

30 Sep '24

Hi all, I'm getting ready to create a pull request to add support for the Toyota eTNGA platform vehicles, specifically the Toyota bZ4X and Subaru Solterra. I’ve been developing this in my fork for quite some time, and I want to make sure the structure of the PR aligns with the project’s standards and expectations. Given the length of time this has been in development, I’m seeking any advice or guidance on best practices for structuring the pull request or specific areas that might need special attention. I’d appreciate any input that can help streamline this process and ensure a smooth integration.

Instructions for building the "new idf" version?

[wow, I guess I suck at mailing lists!] Apologies for asking the list but I'm not having any luck searching the archives by eye, a month at a time (and google doesn't appear to crawl lists.openvehicles.com) Where are the instructions for building the version of ovms that uses a newer idf? What version of the toolchain will I need? Thanks! Craig

access to writer?
by sharkcow 16 Sep '24

16 Sep '24

Thanks for the swift replies! So the deal is I do want to react to a shell command, means I do have a reference to the current writer. But since my code works asynchronously it's not easily possible to pass the writer to the other functions. I'll think about it some more :) I just wanted to return useful information also on the server web shell and Android app since I realized some people don't/can't use the built-in web shell (where I can output everything via log commands). sharkcow > Probably the best you can do is do a log.

Issue with PubSub Example Script
by solterra＠kezarnet.com 11 Sep '24

11 Sep '24

I'm currently working on a script that utilizes PubSub, but I'm running into an issue where the background function doesn't seem to display any output in the shell. I'm following the example from the website: |var myTicker = function(msg, data) { print("Event: " + msg + "\n"); }; PubSub.subscribe("ticker.10", myTicker); | For some reason, I can't get the |myTicker| function to output anything when triggered. It seems like the print statements aren't being executed as expected. Has anyone encountered this before, or does anyone have suggestions on what might be causing this issue? Thanks in advance!

New polling framework example
by solterra＠kezarnet.com 08 Sep '24

08 Sep '24

I'm working on the Toyota eTNGA vehicle integration and had a vehicle module nearly ready to merge last year. Unfortunately, my car broke down, and I've only recently gotten a new one. It seems that the polling framework has changed quite a bit since then. Could someone point me toward a good example of the new framework so I can start converting my module? Thanks in advance for your help!
