CAN communication
2.4.8 Connectors, external interfaces
The WMI is connected with a permanent 12V and the CAN bus, various control signals from the
CAN bus control the WMI and thus bring it into different working modes. In terms of driving
readiness, the WMI represents an interface between the head unit (Can with 250kBaud) and a
standard mobile phone from the driver of the vehicle. To support NFC telematics functions
including identification and data transmission to the vehicle head unit, for example for data
exchange with NFC vCards.

To support these functions, there is a coupling antenna in WMI that fulfills the following functions:
• Interface to the GSM mobile phone via the coupling antenna
• Interface to the NFC enabled mobile phone via the internal NFC antenna
• Interface to the vehicle antenna via the GSM plug connection
2.4.9 NFC vs. Charging
While entering the vehicle and putting down the mobile on to the WMI the mobile will initiate to
the WMI (start of system), while transferring some CAN commands from the car to the WMI.
During the misalignment of the NFC-antenna, no specific NFC-Commands will be send.
Once activated, the WMI tries to detect any device, if an object was placed on the surface. After
a succesful detection of a Qi device, the system switch to Qi-detection-mode.
If the detection-mode has found a mobile with Qi-standard charging possibility on the WMI, the
power contract is established and a charging process will start. If the mobile is removed during
charging from the WMI, charging process is stopped immediately.
The WMI was designed following the Qi standard to charge mobiles prepared for Qicharging. Current versions of the WMI do not fulfill the whole Qi-standard, therefore no Qi Logo
is declared on the WMI and no Qi-certification exists.
