Bosch Power Tools
Data transmission via WLAN
The measuring tool is equipped with a Wi‑Fi® interface which
enables the saved images taken by your measuring tool to be
wirelessly transmitted to a mobile device.
Special Bosch applications (apps) are available for this use.
They can be downloaded in the store corresponding to your
device:
In addition to the wireless data transfer of your images, the
Bosch applications make it possible for you to use an exten-
ded range of functions and make it easier to post-edit and
forward measured data (e.g. via e-mail). Information about
system requirements for a Wi‑Fi® connection can be found
on the Bosch website at www.bosch-professional.com.
To activate or deactivate the Wi‑Fi® connection on the meas-
uring tool, call up the main menu, use the buttons to
select <WiFi> and activate or deactivate it. The indicator (d)
appears in the display when the Wi‑Fi® is activated. Ensure
that the Wi‑Fi® interface is activated on your mobile device.
The connection between the mobile device and the measur-
ing tool can be established after the Bosch application has
been started (if the Wi‑Fi® modules are activated). To do
this, follow the instructions in the application (app).
