Bluetooth connection
There is no need to pair the Bluetooth devices
before launching the FluxManager app.
As
you
launch
the
app,
FluxManager2
automatically scans for available Bluetooth
devices in range, for 5 seconds.
As soon as one or more portable fluxmeters,
accumulation chambers
or soilboxes
are
recognized, they are added to the list, showing the
serial number of the instrument and the MAC
address.
Note: a device will be detected only if in
advertising mode (Bluetooth LED blinking once
every 2 seconds).
The accumulation chamber and the soilbox are
immediately in advertising mode as soon as they
are switched on. The portable fluxmeter runs an
initialization which takes about 20 seconds. During
the initialization, the LED blinks at a greater
frequency, twice per second. When the
initialization is completed, the fluxmeter is in
advertising.
In case a Bluetooth device doesn’t appear on the list once the scan operation is
completed, you can repeat it by pressing the
Scan
button.
On the contrary, if all the expected instruments are on the list, the user can
proceed with pressing the
Connect
button. It is not necessary to wait for the
scan operation to complete before proceeding to connection.
When the user press the
CONNECT
button, the app
tries to connect to one device of each category, if
available. If more that one fluxmeters are in the
range, hence recognized by the app, the user will
be prompted to select which one to connect to.
The same applies to chambers and soilboxes. In
any case the app will try to connect to more that
one fluxmeter at the same time.
Once the connection is established, the Bluetooth
device stop advertising (so they will not be visible
to any Blueooth device). The LED passes from the
blinking to steady-on.
The app shows the sensors detected on each
Bluetooth device. In this phase the sensors are
shown all together.
The real-time reading is shown for each sensor
and updated once per second. The system is now
ready for starting a flux measurement.
The Battery information indicates the voltage of
the 14.4 Volts NiMH battery which supplies the
fluxmeter, placed inside the case.
