Would like to update Dev-Docs
by Soko 15 Jul '20

15 Jul '20

Hey guys, I was able to get everything working and compiling as "portable" installation of ESP-IDF, Visual Studio Code, Git, etc. on Windows. I would like to share it so the next guy doesn't have to go through all the hassle :) I think the best place would be updating https://docs.google.com/document/d/1q5M9Lb5jzQhJzPMnkMKwy4Es5YK12ACQejX_NWE… Can someone grant me access to it? Or should I put it somewhere else? Soko

Unusual simcom hang
by Craig Leres 15 Jul '20

15 Jul '20

My simcom lost its connection between two stops this morning. I happened to check the app when leaving the second stop and it showed the car a few blocks from the first stop. Now that it's back on my home wifi I can see the gps is happy (locked on 10 sats) and the simcom has signal but is in DeniedRegistration state... Looking at https://status.hologram.io/ I see they had an outage today. Ah, checking my other module I see it also says DeniedRegistration. So more accurately: they are *having* an outage today.

Re: [Ovmsdev] Plugin Repository
by Derek Caudwell 15 Jul '20

15 Jul '20

I had to have a few attempts to get he existing plugins working, so a simple repo and install system would be great. May be worth considering the following features from the Kodi addon repo system: - in the root folder there is a consistent name for initial script eg plugin.js - lib folder for including other scripts (could have web folder for html elements) - plugin folder tar/zipped for easy delivery and install https://kodi.wiki/view/Add-on_structure Cheers Derek Date: Tue, 14 Jul 2020 13:45:55 +0200 > From: Michael Balzer <dexter(a)expeedo.de> > To: ovmsdev(a)lists.openvehicles.com > Subject: Re: [Ovmsdev] Plugin Repository > Message-ID: <40cce917-3366-a6e5-1189-a28dc89578d3(a)expeedo.de> > Content-Type: text/plain; charset="utf-8" > > Mark, > > full ack, has been on my list as well.

Hologram outage
by Mark Webb-Johnson 14 Jul '20

14 Jul '20

Craig has let me know of an outage at Hologram. https://status.hologram.io <https://status.hologram.io/> Investigating - We are investigating possible issues connecting to the cellular network for some customers. Jul 12, 18:27 UTC Identified - An issue has been identified with a cellular gateway provider affecting all network connectivity routed out of their global point of presence. Hologram has escalated the issue and is actively monitoring for service recovery. We will further update here. Hologram customers using Indigo SIM connectivity are unaffected. Jul 12, 18:47 UTC Update - Hologram Engineering and Customer Success are monitoring 2G/3G connection/authentication delays due to an increase in reconnection load on those radio access technologies (RATs). Our affected global gateway partner is continuing work to increase signaling capacity for 2G/3G connection/authentication. Jul 13, 22:21 UTC I haven’t had any customer reports of this (other than Craig’s), but be aware of the issue. Regards, Mark.

K-Line and TPMS
by Mark Webb-Johnson 13 Jul '20

13 Jul '20

The K-Line boards are done. Will be available on Fasttech within a day or two. Should also be available in EU and US within a week or two. For the Tesla Roadster, our full write-up of the Baolong TPMS system is here: http://api.openvehicles.com/downloads/TeslaRoadster2_TPMS_Baolong_Engineeri… <http://api.openvehicles.com/downloads/TeslaRoadster2_TPMS_Baolong_Engineeri…> A lot of people put in a lot of work to get this done. I would like to, in particular, single out: Christian for the loan of a TPMS tool Scott for his comprehensive work on LIN bus decoding Peter for advise and pictures of the ECU unit Shawn for his work on the K-line bus decoding Charles for arranging loan of ECU and Antennas Brent for loan of ECU and Antennas Mark for integration to OVMS and adding the K-line option Regards, Mark.

Re: [Ovmsdev] Wifi setup
by Derek Caudwell 12 Jul '20

12 Jul '20

Thanks for the fix! Switching between my APs (all unique ssids, so not tested bssid) works on loss of signal or reboot as expected with the exception that on one running OpenWrt as an extender, so goes back to main router for Dhcp, it is not getting an IP after the switch/gw/dns. I will enable verbose logging later and see if provides more detail on what is happening.

Wifi setup
by Derek Caudwell 11 Jul '20

11 Jul '20

Hi devs, I recently received the ovms hardware and have been trying to setup the unit so I can solely use the wifi AP+client. In NZ 3G is soon to be sunset and for my needs I don't really need a connection when I'm driving (and want to make sure everything is behaving nicely on the can bus before I do). I realise AP+client brings it limitations however hopefully some of these can be worked around as I want to be able to use the dashboard/plugins as well as the mobile app. I am new to C/ESP32 programming and the code base so I thought it best to ask a few questions before I begin tinkering with it. Ideally I want the unit on loss of connection to an AP to try and find another AP that has been set in the wifi config and connect. The parts I am not too sure are as follows: - on boot the code uses the default wifi ssid, if the default is not available how does the code try and switch to one of the other saved APs? - can multiple APs be saved to the wifi config memory and handled by ESP32? or do they need to be retrieved from ovms config, wifi client details set, try connect and enumerated through? - I assume EventTimer10 is the logical place to add extra code if required to enumerate through APs and try to connect? similar to EventScanWifiDone when in SClient mode - What is the reason scanning mode is unavailable for AP+client mode in auto init, from the ESP32 documentation it appeared to be usable still but with limitations? Thanks in advance for any pointers and background. Cheers Derek

Great Michael, Let me know and I'll test the build out. I have a 2016 AZE0 Nismo JDM Leaf and noticed when I turn it on it throws 2 errors repeatedly on can2 (off or charging it's fine). What's the best way to diagnose the root cause of the errors? I assume ovms just ignores traffic it does not recognise, and LeafSpy shows a U1000 DTC on Meter that won't clear.

Hi everyone
by Soko 10 Jul '20

10 Jul '20

Hey, I'm Soko and live in Austria/Europe. I'm a programmer since 20 years now, mainly (big) Windows applications (PowerBuilder, C#, .NET) with databases (MSSQL, Oracle, ...). I also dabble in Arduino/ESP32 programming with little projects for my home since 2 years. I've just bought the new version of the Volkswagen e-Up (equals Skoda citigo and Seat Mii) and was directed to your project by some guys over at www.goingelectric.de. I'd like to contribute to OVMS by adding the e-Up using the standard OBD2 cable (not the Komfort-CAN). My first hurdle though is to get the development environment under Windows up and running. Which seems to be a big task by itself. I guess using Visual Studio Code with PlatformIO (as I do for my Arduino projects) is no option, correct? I have to use this special "ESP IDF" to make it work... Is there any better/newer guide for me than page 6 of the developer guide doc? Thanks Andi
