The Bluetooth thermometer app was created as a nice display of the data from my Bluetooth Thermometer electronic project.
The app uses legacy Bluetooth and therefore is only available on Android as iOS does not support it. This means that you can NOT connect to any Ble (Bluetooth Low Energy) device as it will not be picked up by the app. If you require an app for BLE please have a look at our Bluetooth LE Thermometer app.
Once the app is connected to the Bluetooth thermometer it will start listening for a decimal string ending with “\r\n” as the termination characters and will update the display as it receives data from the Bluetooth Thermometer.
At this point, the app only supports “\r\n” as termination characters, but we do have plans to add other termination strings if people request it.
The Bluetooth Thermometer App has a text display as well as a Graphical Thermometer on the thermometer page. On the Graph page, it has a text display as well as a Graphical Graph display showing the last 30 data points collected from the Bluetooth Thermometer.
You can make your own Bluetooth Thermometer using the HC-05 Bluetooth Module and connect it to an Arduino via the UART/Serial connections. Have a look at the Bluetooth Thermometer electronics project to see how you can make your own.
