Asked questions

Due to an Android 12 update, some Bluetooth devices need to be set up again in your Breathe RM app, for them to work. Firstly make sure you have the latest Breathe RM app (3.10.1 min), then go to Breathe RM settings and delete your spirometer. You can then re-add the same spirometer and it should once again connect.

Location ‘permission’ is a requirement for Bluetooth LE and is necessary in order for our app to connect to your spirometer, oximeter and other devices. No data regarding your location is recorded or stored by the Breathe app.

If the app gets stuck in a ‘connecting’ state, try closing the capture page and retrying. If this doesn’t help, close the capture page before turning your spirometer or oximeter off and on again, then trying again to record a measurement. If you are still unable to record a measurement, turn the phone’s Bluetooth feature off and back on again. Try using the phone’s Bluetooth settings page to search for your devices and create a pairing with it. Finally, restart Breathe app, you should now be able to record the measurement.
