EDIT1:
OTA is currently unavailable. You need to download the preview of 2 binary files manually and execute the flash file on the SDCard.
EDIT2: (2017 June 30)
OTA is now available using the androidthing console .
For automatic OTA updates, you need to create a factory image, then download it and put it on your SD card / board. This happens the next time there is an OS / security update. Updates will be downloaded and installed automatically. You can also update your applications from the console. See the image below and contact for more information.
