This is a simple rust listener app for the mijia bt thermometer/hygrometer. It is built upon bluez dbus api using dbus-rs crate.
The app relies on a simple abstraction of the bluez dbus api that reads the advertisement data broadcasted by ble devices.
On top of that, a mijia bt sensor-specific wrapper abstracts access to the device. It provides a callback to be notified of the temperature/humidity changes.
Each of the two values are stored on a 16 bits unsigned integer. You will need to divide the result by 10 to get the actual decimal value.
The api also provides a start_listening method that take an Option<u64> as timeout. If None is passed, the program runs forever. It still can be interrupted through Ctrl-C.
