Today, we are pleased to release v3.2.002 to general availability. This is the first public v3.2 version, with approximately 200 bug fixes and enhancements (mostly to individual vehicle support modules).

A summary of the major changes is here:

2019-05-12 MWJ  3.2.002  OTA release
- Locations: Introduce support for location actions
- Twizy: Release 1.0.0 -- all V2 features planned are now included in V3
- Vehicle framework: Regenerative braking signal generation
- Vehicle framework: DBC and RETOOLS integrations
- Vehicles: Extensions to Kia Niro, Kia Soul, Mitsubishi, Nissan Leaf,
  Renault Twizy, SmartID, Tesla Model S, and Think City

For full detail on all changes, check the GitHub revision history.

The v3 modules can be updated over the air (wifi), via SD CARD, or over USB - all without requiring special hardware programmers like the PICKIT used for v2. The simplest way to update the module firmware is to connect it as a client to your wifi network (or phone hotspot), and then use the web interface Config / Firmware / Flash-from-Web; that will show you the version you are running, as well as the latest version available for update. One click on 'Flash now' and the update will be downloaded and installed. Alternatively, you can download the firmware update to a file named ovms3.bin in the root directory of a FAT formatted SD CARD and insert the card into the module's slot - the new firmware will be updated automatically and the file renamed ovms3.done to signify completion.

This firmware also includes the feature to check for and automatically update to newly available firmware, every night (so long as the vehicle is connected to WiFi). After updating to 3.1.005 or later, you can enable this for future firmware releases with 'config ota auto yes'. You can choose the release level by setting 'config ota tag edge|eap|main', as one of:

  • edge: Bleeding edge developer nightly-builds
  • eap: Early Access Program (full releases, but with little public testing)
  • main: Publicly tested full releases (the most stable)

Thank you to all the open source developers who have contributed to this, and previous, releases, and thank you for your support of the project.

“Error: ESP32 error #260 when starting OTA operation” — any help is appreciated. Unable to perform the update. Currently on 3.1.008 in a v3 module.

I think that error #260 is a download issue. Can you try again? You can use 'ota flash auto' (when connected via wifi) to force an automatic OTA update immediately. If it still doesn't work for you, then open a support ticket and we'll work through the issue.

Okay, so I am at work now and Roadster is at home. But it is on my home wifi, and I used the OVMS iOS app and sure enough it updated! Looks to be good and working. So indeed whatever the download issue was has resolved. I used the command line in the app as you noted 'ota flash auto' and it went ahead and did the download and updated, pushing back messages indicating it would reboot and such. Thank you for your help!
