7.3 Wi-Fi interface
The use as Wi-Fi interface allows wireless transfer of CAN data to other Wi-Fi
capable devices such as PCs, smartphones or tablets on which CAN data can be
recorded and evaluated�
The device can be integrated in the existing network infrastructure (infrastructure
mode)� In the mini access point mode the device can assume the function of
a Wi-Fi router and provide a wireless network for other Wi-Fi capable devices
in the infrastructure mode� The network parameters can then be provided by
CANwireless via DHCP server�
Data is exchanged bidirectionally as soon as the software has established a
connection to the device�
The ifm maintenance tool is used for the configuration via the CAN interface�
7.4 Wi-Fi configuration
The use as Wi-Fi bridge ensures wireless transfer of CAN data between two CAN
bus systems� In this case, two CANwireless devices replace the CAN cable�
To use two devices as Wi-Fi bridge, one device must be configured as slave and
one device as master� The device is configured as slave by the factory�
The ifm maintenance tool can be used for the configuration�
