The GATT tables used on the

Sentrius™ Sensor are documented in the Bluetooth Developer Studio, a PC tool available from

the Bluetooth SIG. These files are bundled together with the Mobile Application Source code which can be downloaded from
the Software Download section of the

RS1xx Product Page

Note:

The mobile application is written in Xamarin (C#), a product by Microsoft designed for cross-platform (A
iOS) development. The source code for the project is available from Laird as mentioned above.
