Hey Michael Thanx. Does the human readable vehicle ID description ("VW e-Up (Komfort CAN)") matter at all, or will it be filled out automaticly by the new vehicle ID configuration? If not, how do I set that param? Regards Chris Am Mittwoch, den 12.08.2020, 19:18 +0200 schrieb Michael Balzer:
Chris,
yes, that would do. But…
a) you shouldn't overwrite the vehicle name, that's a user configuration, and
b) if you would overwrite the vehicle name, you would set "name" in "vehicle", not "vehicle.name" in "auto" (which doesn't exist).
Regards,
Michael

Hi Michael
I found some time for the "hanging upgrade" issue since we splitted the vehicle ID from VWUP to VWUP.T26 and VWUP.OBD.
Would this code in ovms_config.cpp within OvmsConfig::upgrade() prevent the "hanging" after an upgrade?
// Migrate vehicle ID VWUP to VWUP.T26 if (GetParamValue("auto", "vehicle.type") == "VWUP") { SetParamValue("auto", "vehicle.type", "VWUP.T26"); SetParamValue("auto", "vehicle.name", "VW e-Up (Komfort CAN)"); }
If so, I would put that in a pull request as soon as we have a new "release worthy" version?
Thanx for checking.

Chris,
the framework shouldn't get stuck if a vehicle cannot be loaded, it should fall back to booting without a vehicle. I'll have a look at that.
Btw, to automatically update user configurations, you can extend OvmsConfig::upgrade(). Users shouldn't need to take care of special update preparations.
Regards,
Michael

Welcome to my trial and error T26A world :-))
This morning I flashed the new T26A/OBD version to my OVMS. After the OTA flash the device did not come back to the networks. Only USB terminal access was left.
The reason was, that I did no remove the old vehicle config "VWUP" before flashing and rebooting. The new image has "VWUP.T26" and "VWUP.OBD" as vehicle config, but no more "VWUP". So the device could not find its vehicle config and got stuck.
From the USB terminal I bootet back to OTA_0, said in the vehicle config that my vehicle was a Nissan Leaf and then booted back to OTA_1. The device came up with the new firmware and I could change the vehicle config to "VWUP (Komfort CAN)".
Everything is now running fine ...
I will write this down in the documentation for the e-Up.

Soko,
you only had the door open, but not turned on the car? If there are additional buses, they may be switched off until the car is turned on…
The OBD connector scheme is the general pin assignment, I meant the specific VW e-Up schematics. But if you don't see any voltages with the car turned on, that's bad news.
There may still be some command interface for the OBD gateway to enable live data, but without any info about the gateway, it will be hard to even find out how to address it.

Michael

Hey guys, If I did nothing wrong I have bad news: @Michael:
With OBD port schematics I think you mean this https://en.wikipedia.org/wiki/On-board_diagnostics#OBD -II_diagnostic_connector
Specifically if there are some other pins used than the standard CAN pins 6 and 14.
So I had the drivers door open, no key in ignition and measured the voltages of all pins in relation to pin 5 (signal ground). There is no voltage on any pin besides 2.5V on 6 and 14, and 12V on 16 of course. So there are no hidden CAN buses (or any other signals) afaict. @Mark:
Thanks for the hint with the can log. It's way easier than RE Tools for just checking if there is any traffic.
Having said that... there is no traffic whatsoever besides what I am polling and the reply. Even when ignition is on I only see the poll and the reply on the can log So it seems devmarxx was right: The gateway shields everything and there are even no other hidden signals on the OBD port. I'm happy to try any other ideas you guys have. Just let me know! Soko
