Developers have been able to create apps for the SmartWatch using the Sony Add-on SDK for quite some time already, however, with the Open SmartWatch project, we’re opening up the device even more. If you’re an advanced developer, you can now take control of SmartWatch as a hardware peripheral in new ways by creating and flashing your own alternative firmware.
Currently, there are no alternative firmware versions for SmartWatch, but we hope that that the Open SmartWatch project will inspire and make it possible for you to create new innovations.
Sony is holding a SmartWatch Arduino Hackathon in Malmo, Sweden together with Arduino who will offer a tool chain enabling Arduino firmware to run on the SmartWatch.
The company has also posted a "Hacker guide" with technical information and instructions on how to flash the SmartWatch. It contains information about the display, Bluetooth, I2C peripherals, touch sensor protocols and more.
