Trying to get a new car in, CRTD, CANbus and all

Hi everyone, and happy summer to all ! So, sold my Twizy a month ago, the OVMSv3.1 has left with it, got a VW e-UP! a little bit before and received a v3.2 last week. Threw away a few microSDs but got a CRTD log this afternoon. While I have the weird impression 1335 lines and 55kB ( https://pastebin.com/FAZqnzie ) for a 30 minute drive back from work seems very short, I tried reading it in SavvyQT but it “salvages” only the first 35 lines. (30 minutes kinda full left aside the wipers, ignition off, on, launch, lights, windows, reversing, and even blinkers that Parisians try to avoid using for some odd reason, so yeah, 1335 lines, that’s not even a frame per second, something is missing) No DBC found on the interwebz for volkswagen’s AA/12 platform, so I’m in for making a first probably ? That is if the sole CANBus connected got anything worthy (OBDII vehicle module used) I have understood VAG cars are a bit different in a way, I wouldn’t be surprised accessing VW busses need a bit of help :) Anybody around with a bit of knowledge with these cars ? Best, JaXX./.

I managed to recreate this (it is very rare for me), with logging enabled to SD CARD. Here is what I saw: 2019-07-07 21:37:13 HKT I (66811669) events: Signal(location.enter.honghay) 2019-07-07 21:37:14 HKT I (66813039) events: Signal(system.event) 2019-07-07 21:37:14 HKT I (66813099) events: Signal(system.wifi.scan.done) 2019-07-07 21:37:54 HKT I (66853039) events: Signal(system.event) 2019-07-07 21:37:54 HKT I (66853099) events: Signal(system.wifi.scan.done) 2019-07-07 21:37:54 HKT I (66853159) esp32wifi: Found SSID <REDACTED> - trying to connect 2019-07-07 21:37:57 HKT I (66855679) wifi: n:13 0, o:13 0, ap:255 255, sta:13 0, prof:1 2019-07-07 21:37:58 HKT I (66856619) wifi: state: init -> auth (b0) 2019-07-07 21:37:58 HKT I (66856679) wifi: state: auth -> assoc (0) 2019-07-07 21:37:58 HKT I (66856749) wifi: state: assoc -> run (10) 2019-07-07 21:37:58 HKT I (66856809) wifi: connected with <REDACTED>, channel 13 2019-07-07 21:37:58 HKT I (66856859) wifi: pm start, type: 1 2019-07-07 21:37:58 HKT I (66856919) events: Signal(system.event) 2019-07-07 21:37:58 HKT I (66856989) events: Signal(system.wifi.sta.connected) ... 2019-07-07 21:37:59 HKT I (66858139) events: Signal(system.event) 2019-07-07 21:37:59 HKT I (66858199) events: Signal(network.interface.up) 2019-07-07 21:37:59 HKT I (66858269) events: Signal(system.wifi.sta.gotip) So, I drive home, it does a wifi.scan, finds my home AP, connects, and all is ok.

It is not a solution, but a clue as to at least one cause of these problems. From what I can see, the wifi got starved of CPU during that horribly long flash erase process, then wifi connection went down, OTA update failed, and it wasn’t recoverable from there. Perhaps if the STA gets disconnected (always, or just with reason 200?) we should reset the wifi stack? The root cause of that esp_ota_begin() starving the wifi during erase of the 4MB partition would also be good to address. Regards, Mark.

BUG? in v3.2.0-1 in vehicle_mitsubishi - flood of BMS-error msg
by Michael Eric Menk 11 Jul '19

11 Jul '19

There is a bug in MIEV code, that bombs the web GUI and phone APP with BMS errors. I suspect that this is because the Peugeot and Citroen branded MIEVs have a 80 cell battery pack vs MIEVs 88cells. Sample of a message: > Voltage: SD=1mV OK > Temperature: SD=1.4C !6:+3.1C !16:+3.1C !18:+3.1C The missing cells could also be used to set the voltage gauge. There are two LEV50-4 missing in the 80 cell pack, number 06 and 12. If a flagg is set while looping the CAN massages, then the flag can be used inside OvmsVehicleMitsubishi::GetDashboardConfig to set correct voltage. The float charge voltage of the 80 cell pack is 328.4 volt

Documentation
by Mark Webb-Johnson 05 Jul '19

05 Jul '19

The google doc user guide we have is really not working out. Not searchable, not indexed anywhere, not friendly for the end-user, and hard to maintain as a team. So, we’ve setup a readthedocs repository for documentation, and adopted the Sphinx ‘docs’ standard for documentation. The User and Vehicle guides have been ported over to this new system, and are live now: https://docs.openvehicles.com/ <https://docs.openvehicles.com/> The way the system works is that documentation is written in reStructuredText (rst) format, stored in ‘docs’ directories in our main code github repository, and processed by the Sphinx documentation system to produce HTML, PDF, ePub, etc documentation. I’ve created a top-level ‘docs’ directory, as well as individual ‘docs’ directories in each of the vehicle support components. That way, each vehicle developer has control over their own vehicle documentation, and it all gets compiled and made available online automatically. Documentation changes are incorporated in exactly the same way as code changes - by github pull requests - and you can keep your documentation up to date with the code. Screenshots and other images can simple be loaded into the ‘docs’ directory and displayed inline using reStructuredText directives. A good introduction to the available markup directives is here: http://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html <http://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html> There are also lots of examples in the documentation we have already produced. When we commit to github, a trigger fires and notifies the readthedocs service that we have changed. That service then rebuilds the documentation (usually within a few seconds, or a minute at most), and makes it available as html, pdf, ePub, etc. It also supports version control (using github release tags), and language translations. If you are doing a lot of work on documentation, you can install the sphinx tools locally (I simply use 'pip install sphinx'), and ‘make html’ to build documentation locally (then view it in your web browser as a local set of files). So far, the user and vehicle guides have been ported over pretty much ‘as is’, without changes. We can now work on improving them, and trying to come up with a quickstart type of installation guide to cover the basics, with advanced topics available for the more adventurous. The next step will be to address the developer documentation. We should be able to include this inline with the code, and have Sphinx extract the classes and methods automatically to build developer guides. Regards, Mark.

3G network
by Stein Arne Sordal 03 Jul '19

Hi I guess this question is basically for Mark, In Norway the telecom providers have decided to turn off almost all of the 3G network soon and focus on 4G only. Any plan for 4G modem? Kind regards, Stein Arne Sordal
