Connecting a group of iPads/Androids to a V-Log
It is possible for a group of devices to connect to one V-Log WiFi simultaneously to allow students to work
collaboratively on a single experiment.
Note: Performance maybe impacted if lots of devices are connected to the same logger.
When connecting to V-Log, the first iPad/Android/Windows PC to connect is given 'control' of the logger
and will therefore be able to setup, start and stop the experiment. All subsequent devices that connect to
the logger are given 'Viewer' status, they will see the set up changes made by the controller, and as data
is captured it will appear in real time.
When recording stops, all iPads/Androids automatically save the captured data into their internal memory.
One iPad/Android cannot change or delete the data held on another iPad/Android.
To leave a group, simply tap on the connection status button to disconnect (iPad users this is bottom right
of the screen, Android users top right of the screen).
When the controlling iPad/Android disconnects this will disconnect all the others. A new controlling
iPad/Android is chosen by ensuring that it is the first to re-connect.

V-Log in Bluetooth mode
If V-Log has a Bluetooth board fitted it can be used in Bluetooth mode. If using V-Log battery powered in
this mode, fully charge the battery before use e.g. leave to charge overnight for use in lessons the next
day. When the battery is in good condition and fully charged it will power a Bluetooth connected V-Log for
about 8 hours.
Note: V-Log stays awake while Bluetooth is turned on. Disconnect after use as the battery will continue to drain if V-
Log is stored with Bluetooth still selected.
Ensure the firmware of V-Log is at least V1.9 or higher.
Do NOT pair the devices (when paired V-Log will not be made available to the EasySense software).
