More information and details will be added
Bluetooth Smart is a new standard that allows Bluetooth equipment to run for years on a single coin cell battery. According to IMS Research the market for Bluetooth Smart accessories is expected to be the fastest growing mobile phone accessory market in the coming years. This new technology combined with new low power sensors and countless mobile phone app developers opens up limitless opportunities for mobile phone apps
The SensorTag is designed to shorten the design time for Bluetooth app development from months to hours, the kit removes the barriers to entry for smartphone app developers who want to take advantage of the growing number of Bluetooth low energy-enabled smartphones and tablets. This is the first Bluetooth low energy development kit focusing on wireless sensor applications and it is the only development kit targeting smartphone app developers.
The Bluetooth SensorTag demonstrates the low power capabilities of Bluetooth low energy(aka Bluetooth 4.0 and Bluetooth smart)
- NO embedded software design knowledge required
- NO embedded compiler required
- Includes 6 low-power MEMS sensors and Bluetooth low energy radio powered by a single coin cell battery
- iOS and Android sample apps are included to demonstrate use of the sensorswi
The SensorTag can be used as a reference design and development platform for a variety of smartphone accessories.
The block diagram shows the sensors on the SensorTag and lists some potential applications, most engineers that start working on the SensorTag comes up with their own app ideas!

With the SensorTag App you can build your own SensorTag app in minutes by enabling the SensorTag sensors. It allows quick and easy prototyping and generates sample code for use in your own apps. The iOS SensorTag app can be downloaded from the Apple App Store
Supported iOS devices
To use the SensorTag a Bluetooth Smart (4.0 or newer) device is required and the API of the device must support the Bluetooth low energy API. Currently the following iOS devices are supported:
- iPhone 4S and newer
- iPad(3) and newer
- iPad mini
- iPod Touch (5. gen)
The Android SensorTag app is distributed as an Application Package(.apk)
Download the SensorTag Android App here: SensorTag Android App (Rev. 1.10)
The source code is included in the installer. For further enquiries please contact j.boe(at)ti.com
Supported Android devices
To use the SensorTag a Bluetooth Smart (4.0 or newer) device is required and the Android API 18 (Android 4.3) must be supported. The SensorTag app has been tested on the following Android devices:
- Nexus 4 (JWR66V)
- Nexus 7 (2012) (JWR66V)
- Nexus 7 (2013) (JSS15J)
- Samsung S4 (JWR66V.S11.130708)
- HTC One (0.1.0.0 - 20130728)
Support for more devices will be announced. If you have tested other Android devices, please join the discussion on the Bluetooth low energy forum
NB! Nexus 7 (2012) with Android 4.3 is not delivered with BLE enabled. To work with BLE on this device you will need the Bluetooth Low Energy Enabler tool. Prerequisites for this to work is that the device is rooted and that the BusyBox app is installed.
For Android the connection interval is currently fixed to 7.5ms. With early versions of the SensorTag firmware this is causing a timeout when using the humidity sensor. This problem is fixed with the latest version of the SensorTag firmware(1.4). To use the SensorTag with the Android apps, download the latest firmware here: SensorTag firmware
New firmware can be programmed with binary files over-the-air using the Windows BLE Device Monitor, the latest version of the SensorTag Android app, or with hex files using CC-Debugger.

SensorTag User Guide
The User Guide provides all details of the SensorTag hardware and firmware including conversion algorithms and overview of Bluetooth low energy commands used to communicate with the phone
SensorTag User Guide
How to Certify your Bluetooth Product
The SensorTag reference design has passed FCC(US)/ETSI(Europe)/IC(Canada) RF certification. It is also received Bluetooth End Product certification. This section explains what certifications the SensorTag has completed and the steps required to certify your own product: How to Certify your Bluetooth product
Not ready to go through full FCC/ETSI certification? Use certified modules from our 3rd party partners: [Bluetooth low energy modules]
BLE Device Monitor User Guide
The BLE Device Monitor is a PC tool that allows you to read and write the characteristics of Bluetooth low energy devices. For the SensorTag the BLE device monitor includes a production test panel that for testing the individual sensors. It can also be used to display sensor readout continuously. The BLE device monitor requires a CC2540 USB dongle
BLE Device Monitor User Guide
The BLE Device Monitor has been tested on Windows XP, Windows 7 and Windows 8.

Dave The Android Guy
This blog By David Johnson explains how he modified a SensorTag to interface it to an exercise bicycle trainer. He has a video of his mother using the exercise bicycle while he monitors her progress on a Nexus 7. His goal is to make an interface to allow people to exercise and navigate Google Street Views. According to David he does Android Systems development for "People that deserve more and have less"

Driving AutoCad using a SensorTag
Take a look at this blog post to see how the SensorTag is connected to AutoCAD to rotate objects,
A framework for building Bluetooth 4.0 Low Energy (aka Smart or LE) iOS and OS X applications using the CoreBluetooth API. Includes Deanna and DeannaMac, applications to communicate with a TI SensorTag for iOS and OS X respectively.
Intended for iOS and OS X developers intent on shipping production-level code to communicate with BLE devices. Think of it as AFNetworking for BLE.
- ObjectiveC Block-based API for Bluetooth LE communication
- Operations (e.g. scanning, retrieval, connection, reads, writes) map to the data object hierarchy of CoreBluetooth.

YmsCoreBluetooth in Action
SensorTag as iTunes Remote
Here is a video of an iOS app running in the background using YmsCoreBluetooth to characterize the SensorTag to control the Music app on an iPhone. Using YmsCoreBluetooth, time spent making this demo from concept to execution (including shooting the video) took a half-day, just in time to head for lunch.

SensorTag library for Windows Store apps in C#
An easy to use C# library for Windows Store apps. This library uses the new GATT API available in Windows 8.1. Assembly, source and a sample are available at CodePlex: http://sensortag.codeplex.com/
There's also simple app available in the store: http://x2codinglab.com/component/k2/item/29-ti-sensor-tag-reader
Best TI SensorTag BLE
The Windows "Best TI SensorTag BLE" app is available from the Windows App Store. The free app provides basic access to the different sensors; with a low-cost in-app upgrade, data can be copied in tabular form. The in-app upgrade also provides access to the source code for the entire app. Many laptops and tablets are already Bluetooth 4.0 compatible; other computers may require a Bluetooth dongle to function correctly.
