Hi there all, I have 2 of the latest units, and I am running a Nissan Leaf and e-NV200.. I have 2 questions 1. Is there an API for dexter-web.de <http://dexter-web.de/> site? 2. Is there any updated documentation on the current API on TMC? Thanks Tim

3G network
by Stein Arne Sordal 02 Jul '19

02 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

Can buses stop after some time
by Tom Parker 01 Jun '19

01 Jun '19

Hi all, I synced up with master about a week ago and since then I've seen both can busses stop working. I still see the 12v battery metric changing, but everything that comes from the car stops. Rebooting the module with "module reset" does not seem to fix it, while make app-flash monitor does fix it. I haven't tried make monitor on it's own. Is anyone else seeing behavior like this? Sorry for the vague bug report. I'll spend some time later this weekend to try to gather more information.

Garbage in /store
by Stephen Casner 27 May '19

27 May '19

When I do "vfs ls /store" I get 128 lines like the following: -2146205 01-Jan-1970 00:00 ????????.??? After that comes valid content: [DIR] 01-Jan-1980 00:00 ovms_config/ 83 01-Jan-1980 00:00 .htpasswd The config facility appears to be intact. Does the garbage indicate that the /store filesystem is scrogged and needs to be rebuilt? -- Steve

Android App v3.12.2 in Play Store
by Michael Balzer 07 Apr '19

07 Apr '19

Whoa. Our first public App update since …drumroll… June 2014 :) I didn't get any bug reports for my 3.12.2 beta release, so I just finished some last details and uploaded it. May take some hours to appear in the Play Store. As change history has grown a bit beyond the allowed 500 chars for the release info, I've added a history page to the Wiki: https://github.com/openvehicles/Open-Vehicle-Android/wiki/History I'm afraid it's just the condensed gitlog though. I hope users won't get confused, sure could need some refinement. Regards, Michael -- Michael Balzer * Helkenberger Weg 9 * D-58256 Ennepetal Fon 02333 / 833 5735 * Handy 0176 / 206 989 26

Power states clarification
by Greg D. 02 Mar '19

02 Mar '19

Hi folks (mostly Mark, probably), I just noticed that there is a power command for OBD2ECU as well as ext12v. I understand (or thought I did) what controlling the ext12v power does, but how is "power" related to OBD2ECU? Is this related to firing up the opened CAN bus, or is there some tie to the ext12v power? I have manually created scripts for vehicle.on and vehicle.off to explicitly control ext12v, so that an attached HUD will follow the key. We talked about having this sort of thing done automatically, but I didn't think it was ever implemented, nor what the particulars would be regarding some of the device corner cases. Is that what is happening here? Related, what do the other states do? (Sleep, deepsleep, etc.) Thanks, Greg

Collecting information on the Fiat 500e
by Jason Perkins 14 Feb '19

14 Feb '19

OVMS team, As an owner of a Fiat 500e I was very interested when I stumbled across this project on the TMC forums. The Fiat factory telematics system deactivates 3 years from the original vehicle sale and is non renewable. I think FCA wants to kill the whole system at this point (it's been replaced with the corporate UConnect system) so another solution would be ideal. I have a 2013 500e with deactivated telematics, and our roommate has a 2014 with working telematics. If any data could be captured from the car with working telematics (branded as Fiat Access) to assist integrating OVMS I'd love to help. The Fiat Access telematics provides vehicle location, battery level, tire pressure, setting the charge schedules, locking / unlocking the car, and starting the climate control. I believe the actual control unit was adapted from some kind of remote-disablement system used in europe (the Fiat literature calls this the Vehicle Tracking Module). The Fiat has a normal J1962 plug, but does not have OBDII protocol support. Like the Kia Soul the powertrain CAN on pin 6 / 14 and the body CAN on 1 / 9. There's no telling how long the telematics will keep working on our roommates '14, so doing a capture sooner than later would be good. I'm open to any suggestions on how best to do this. The car related diag tools I have on hand are: ELM327 Bluetooth, Ross-Tech VCDS (For VW / Audi Products), and AlfaOBD (which can talk to most of the modules in the 500e - but not the VTM :( ), and an adapter to swap the CAN wires so a standard interface can get to the Body CAN. Thanks! -J

Re: [Ovmsdev] OvmsDev Digest, Vol 83, Issue 5
by Olivier 27 Jan '19

Hi Mark, Before the update code is working to but with some error, I will fix my dbc file to add signal for all message. I have two question : 1. do you know how to config the dbc file to "compile" data from 2 Btye not contigu ? Example : ID 00FDF040 8 0x85 0x85 0x81 0x6A 0x7A 0xD9 0x4C 0x2E // ID message contain 5 Cells Voltage Cell 1 : #Byte 0 (0x85) | #LowByte 5 (0x9) => 0x859 => 2137 * 0,0015 = 3,2055Volts Cell 2 : #Byte 1 (0x85) | #HighByte 5 (0xD) => 0x85D Cell 3 : #Byte 2 (0x81) | #LowByte 6 (0xC) => 0x81C Cell 4 : #Byte 3 (0x6A) | #HighByte 7 (0x4) => 0x6A4 Cell 5 : #Byte 4 (0x7A) | #LowByte 8 (0xE) => 0x7AE the last Byte is the ID of BMS Board (0x2?) 2. The next step do after dbc load, How I can use information the value to map or link with Standard metric ?

How can I help
by Robert Sharpe (Electric Vehicle Consultant) 25 Jan '19

25 Jan '19

Hi All, I like where OVMS project is going and would like to help if I can. Where I can possibly add value is make things easy for people to use (eg documentation, etc) experienced on UI/UX design, etc. as an ex developer, good at testing and finding problems. Some initial thoughts on activities are to make it easier for non technical people to use OVMS, help doc author pull out user only specific content to a user manual and make it non-technical (renaming current user manual to developers manual) to help people see roadmap, provide a mechanism to see who wants what and who is working on it. to allow developers and users to display problems with their vehicle only, add Labels to the github issues list or group by project (I am not an expert on GITHUB so please be patient) update GITHUB readmes to better direct people that find GITHUB first. Please let me know if anyone is dealing with any of these areas add and/or vote for what things you think I can help with by putting a comment next to the activity above. Regards, Robert Sharpe Electric Vehicle Consultant 07711 252971 Your Plugged-in Partner Evergreen Consulting is the trading name of Sharpe Consultants Ltd
