The ODK Sensors Framework is just that -- a framework -- layered on top of
the lower-level interfaces to USB and Bluetooth functionality and the
built-in sensors on the device. Installing the ODK Sensors Framework
installs just the framework.
Currently, the only sensors-framework-based functionality that we have
released to Google Play is the Zebra printer driver.
Information on the steps for configuring sensors and the printer driver is
You must write the equivalent of a "user-mode driver" in order to use the
sensors framework. By subclassing from the provided core sensors library,
the actual amount of code you need to write is very very small (the Zebra
Printer source code is a good example of how little is needed).
The sensor drivers we have developed are available as source here:
These are all considered to be pre-ALPHA, except for the Zebra Printer
Driver, which is Production. The framework itself should be considered to
be in alpha for high-data-rate communications. It is quite stable
(production) for lower-data-rate uses.

I have been trying to figure out how to use ODK Sensors. Since the app is
available in the Google play, I was hoping it to be functional to some
degree, however, when I open the app, I am stuck at the screen with ODK
Sensors logo and nothing happens. I tried this on Samsung Galaxy Note,
Samsung Galaxy tab 2 and Nexus 7 with the same results. I was expecting
something similar to screenshots in the Google play app description. Did
anyone get it to work?
We have developed apps to support bluetooth based barcode and fingerprint
scanner with ODK Collect and we're really interested in checking out what
this sensors framework offer.
