The Bluetooth connection is retained until the devices
®
are either out of range (range max. 30 metres in the free
field; much less inside buildings), the Bluetooth function
®
and/or the app in your mobile end device is switched off
or the thermo logger is deleted from the directory of the
app.
When the Bluetooth connection is interrupted, the app
®
will no longer show any measured values. The symbol
L Pr o
for Bluetooth in the thermo logger display is no longer
®
lit either. If the devices come back into range or the app
is started again (the devices must be in range of each
other for this), the Bluetooth connection will be auto-
®
matically re-established.
