CC3200 SensorTag
As reported yesterday, the CC3200 Wi-Fi SensorTag has been officially released, retailing at $39.99 from the TI Store. This page hopes to aggregate the new SensorTag links in one place. If you know of any fresh information, place them in the comments, or this 43oh discussion thread.
The new SensorTag is based on the SimpleLink Wi-Fi CC3200 device which is a wireless MCU that integrates a high-performance ARM Cortex-M4 MCU. The biggest advantage of the new Wi-Fi tag is its ability to directly connect to the web without the need of a gateway, which the multi-standard tag required. According to TI’s FAQ, The Wi-Fi SensorTag app is supported on iOS and Android as well as the IoT Device Monitor for Windows PCs. The tag is powered by two AAA batteries and can last for three months with one minute update intervals. The range on the SensorTag is estimated to be around 100m.

Key Features
- CC3200, SimpleLink Wi-Fi, Internet-on-a chip solution with integrated MCU.
- Onboard 1-MB serial flash memory.
- Onboard inverted-F antenna with RF connector for conducted testing.
- Two buttons, two LEDs, reed relay, digital microphone, and a buzzer for user interaction.
- Sensors include a gyroscope, an accelerometer, and a compass for easy integration in IoT application.
- Debug and JTAG interface for flash programing.
Sensors
The Wi-Fi SensorTag kit has 9 integrated low-power MEMS sensors, similar to the multi-standard tag. These include:
- OPT3001 – Ambient Light Sensor
- TMP007 – Infrared Thermopile Sensor with Integrated Math Engine
- HDC1000 – Low Power, High Accuracy Digital Humidity Sensor
- MK24 Series Reed Sensor
- Knowles SPH0641LU4H Digital Microphone
- MPU-9250 Nine-Axis (Gyro + Accelerometer + Compass) MEMS MotionTracking™ Device
- BMP280 Barometric Pressure Sensor
The Wi-Fi SensorTag kit includes 9 low-power MEMS sensors. In addition it can be expanded with the Watch DevPack for applications requiring displays and expanded with USB power with the Debug DevPack.
DevPacks
DevPacks are plugin boards that can backpack over the SensorTag. The display shows important status information and technical data that is useful for debugging network settings. TI recommends the following two DevPacks. However, the wiki does show images of the Wi-Fi SensorTag with a Display DevPack. Although it does look like the “Display” and “Watch” Devpack go by the same name.
CC3200 Wi-Fi SensorTag with the DisplayDevPack
The following Devpacks are supported according to the FAQ:
- SimpleLink SensorTag Debugger DevPack
- SimpleLink SensorTag Watch DevPack
SimpleLink SensorTag Debugger DevPack
Watch DevPack

Programming
There is currently not much information on programming the Wi-Fi SensorTag. However, since it is based of the CC3200, it can be programmed in a way similar to the Launchpad version of the CC3200.
Firmware Upgrade Information
This is detailed in pg.9 of the user guide. If an upgrade has already taken place and a newer firmware version becomes available, users must first revert back to the factory default (firmware version 0.98). This can be done in one of 2 ways:
- In the mobile application, select Firmware Upgrade → Factory Default.
or - Depress the two SensorTag hardware buttons simultaneity for a few seconds until the beep sound is
activated.

Super! Thanks for curating the links!
I was unable to find any battery life details on this. Any info?
If left constantly on battery life (I used Eneloop Rechargeables) was about 24h. I am disappointed in the lack of proper documentation. What could find out I have listed on my Github page.
Added your link to the post under “User Contributions”.
If there are no plans to release the source code for this device, and the only way to upgrade the firmware is via OAT, what is the point of the SimpleLink SensorTag Debugger DevPack for this device?
Yours Simon M.
I have spent hours trying to get help on programming my two units! the first no longer even shows up in the list of wifi devices on my iPhone. The second has always showed up but asks for password! Duh? I bought the watch display (very cool) and now the debug devpack! I don’t even think this works with the CC3200Sensor Tag! The TI guy on e2e convinced me I needed a Launchpad! No mag sensor so I can’t show my customer his demo anymore! I have been doing TI BLE for over 3 years! We need WiFi to get to the cloud, BLE, (a mag sensor would be great), and a USBport! What am I missing? Thank you, Ed
Wrong. TI web states that all devpacks are
*Only compatible with CC2650STK and CC1350STK
…And no source code available. So how do I do programming on it?
Lucky — I found it before I buy one and start testing it! Now I’m turning to other competing IoT products (Silicon Labs, Nordic, Microchip etc? 🙂
Unfortunately, yes. TI does not provide source for the Wi-Fi SensorTag. It does throttle the use of the kit as a development system.
So whats the point of this sensor tag if you cant program it?
I’m glad this question received so many reactions.
After many hours of working with the CC3200 SensorTag here are my conclusions:
– It is impossible to register a Wi-Fi profile on the 192.168.1.1 configuration page. That functionality is only there on paper. After you successfully save a profile it asks you to perform a reset. However, the device’s manual states that a reset clears all previous Wi-Fi settings.
– It is possible however to provision the device from the iOS version of the SensorTag app. I highly recommend turning on the ‘Stay awake’ functionality under OTA upgrade, that way the device can continuously send data for about 1-2 hours before dropping the Wi-Fi profile. Then you have to provision it again. The IBM quickstart service seems to be the best solution, on this link: https://quickstart.internetofthings.ibmcloud.com/#/device/XXXXXXXXX where XXXXXXXX is the mac address of the SensorTag (without the : characters)
– It is only possible to provision the SensorTag from certain Android versions. My phone didn’t work, and another one did, so I’m not sure about the details. You just have to try your luck I guess.
It is truly a demonstration device that can be used during an expo or school lecture or something. You can give it out to people to play with and see live data on the Quickstart service. That’s it.
