The wireless communication of the Scan Mon-
itor is supported by a BLE communication.
This communication is established between
the Scan Monitor and the Withings App. The
communication between the Scan Monitor and
the Companion app is encrypted through an
exchange of a paired key.
The communication latency between the Scan Monitor and its
companion app is inferior to 10 seconds. A maximum operating
distance of 5 meters allows a latency inferior to 10 seconds. The
communication security is implemented by default (encrypted
communication).
The Withings app shall be downloaded from official stores (App
store and Google Play store) and smartphones shall be up to
date. Versions supported by the companion app and the Scan
Monitor are iOS 15 or later or Android 9 or later.
In case of communication failure, you should follow the relat-
ed troubleshooting. Measurements are stored within the Scan-
Watch 2.
The communication between the Scan Monitor and the compan-
ion is not modified with sources of interference signals located
within 5 meters.
This wireless coexistence has been tested in accordance with
the following standards:
- ANSI C63.27:2017 and,
- AAMI TIR69:2017
Electromagnetic disturbances have been tested in accordance
with the standard IEC 60601-1-2:2014.
