+# CoreTemp display
+
+Basic bare-bones example of connecting to a bluetooth [CoreTemp](https://corebodytemp.com/) device and displaying the current body core temperature readings.
+
+## Usage
+
+On startup connects to a CoreTemp device (1809/2A1C) and emits a "Core, temp" value for each reading.
+The app simply displays these readings on screen.
+
+## TODO
+
+* Integrate with other tracking/sports apps to log data.
+* Add device selection
+* Provide enable/disable option
+* Check status, add Retry/reconnect
+* Also provide skin temp reading
+
+## Creator
