CANwireless

6

4 Function

The device allows wireless access to the CAN interface of mobile machines for data exchange or error
diagnostics.

The device has an internal antenna.

The parameters of the device are set via the CAN interface.

4.1 CAN bridge via Bluetooth

The CAN bridge via Bluetooth enables M2M (machine-to-machine) communication between two
machines. The CANwireless devices connect via Bluetooth and exchange CAN messages. This
replaces the physical CAN cable.

Communication via Bluetooth is recommended because the Bluetooth frequency band is
used significantly less than the WLAN frequency band. The connection between the
machines is thus more stable and less disturbed.

4.2 CAN bridge via WLAN

The CAN bridge via WLAN enables M2M (machine-to-machine) communication between two
machines. The CANwireless devices connect via WLAN and exchange CAN messages. This replaces
the physical CAN cable.

4.3 CAN via Bluetooth interface

Using the Bluetooth interface, the device can establish a connection to other Bluetooth devices such
as smartphones, tablets or laptops. The CAN data is transferred to the connected device and can be
stored and evaluated there. The CAN data is formatted with the Byte Command Protocol and then
transmitted via Bluetooth. For more information about the byte protocol, see the document
“Programming manual - API Description - Byte Command Protocol”.

4.4 CAN via WLAN interface

Using the WLAN interface, the CANwireless device can establish a connection to other WLAN devices
such as smartphones, tablets or laptops. The CAN data is transferred to the connected device and
can be stored and evaluated there.

Using the CAN connection via the WLAN interface, two different operating modes (WLAN operating
modes) are possible:

Infrastructure
In the operating mode “Infrastructure”, the CANwireless device connects to an already existing
WLAN network. This can be a company network or an access point.

Mini Access Point
In the operating mode “Mini Access Point”, the device creates its own WLAN network to which
other devices can connect to. The CANwireless device can handle and manage a maximum of
seven simultaneous connections at a time.

In both operating modes, the CAN data is formatted with the Byte Command Protocol. For more
information about the Byte Command Protocol, see the document “Programming manual - API
Description - Byte Command Protocol”.
