Welcome to the main page for the Bluetooth SensorTag

The SensorTag now supports iBeacon technology!

To upgrade your SensorTag to be compatible with iBeacon technology you need to sign up as an iBeacon licensee with Apple, then you can request access to the software by clicking here

Once you signed up as an iBeacon licensee you can upgrade the SensorTag with the latest iBeacon enabled firmware to test and develop with iBeacon.

SensorTag with iBeacon

Instructions how to do the upgrade and configuring an iBeacon follow this link: SensorTag_with_iBeacon

For more information how to use the Sensortag with iBeacon, watch the SensorTag iBeacon video.

The new location app with iBeacon technology is available to download on the App Store for iPhone, iPad and iPod touch.

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 sensors
SensorTag Block Diagram

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!

Buy the SensorTag on TI eStore

iOS

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)
SensorTag Assembly Instructions

SensorTag IR temp sensor used for measuring coffee temperature
SensorTag used as keyfob for tracking keys
SensorTag accelerometer used as level construction tool

Android

NEW! The Android SensorTag app is now available on Google Play Google Play SensorTag

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)
  • Nexus 5 (KTU84M)
  • Samsung S4 (JWR66V.S11.130708)
  • HTC One (0.1.0.0 - 20130728)
  • Sony Xperia E1

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 and Nexus 10 (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.

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"

YmsCoreBluetooth

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.

Features

  • ObjectiveC Block-based API for Bluetooth LE communication
  • Operations (e.g. scanning, retrieval, connection, reads, writes) map to the data object hierarchy of CoreBluetooth.
