## What is Bluetooth LE Thermometer?

The Bluetooth LE Thermometer App connects to a Bluetooth low energy thermometer hardware device.  The app updates temperature in real-time. The app currently has a thermometer view and a graph view.

For the app to work, the device should transmit temperature readings over serial via an AT-09 or similar BLE device with a "\r\n" termination string.

The AT-09 is popular for DIY projects where hobbyists could make their own devices and use apps like this one to test it. You can make your own device using an Arduino or similar microprocessor, with an AT-09 or similar BLE device. 

You can use an existing device if it uses similar internal hardware and data string. If you find that a device does not work with our app, let us know what device it is, and we'll either update our app to support it or add it to the unsupported list.
