While the app should automatically reconnect to the device if a disconnection occurs (for example,
the device leaves the Bluetooth range, or the device is rebooted) it is possible to end up in a
situation where there is no connection. In this case, the menu will only have one button:
Connect
.
This will connect to the device that the app was previously connected to. To bring up the SCAN
screen again, close the program completely (usually done from the square button on the bottom of
the screen) and restarting the app.

Recording raw data and streaming PPG
To record raw data, you will need to enable raw data collection. From the extra menu, press
Continuous mode
and then choose either
RAW
or
RAW+HR
depending on which data you want to
store in the database. The device should vibrate to mark the switch in operating mode.
If only
RAW
is selected, the device display and the app will not show HR, steps or burned
calories.
To stream the PPG, click the “Raw Data” screen (that should now say “On”) to bring up the PPG
demonstration screen. It shows the past few seconds of the PPG raw data and the HR and steps
values in addition.
