Once you have either configured a USB Bluetooth dongle or a Bluetooth CF card, you can transfer
files between the mobile and the Zaurus wirelessly using the OBEX via bluetooth mechanism. See
the bluetooth section for more details.
Controlling the phone with the Zaurus
The K750i also offers a virtual serial interface that can be used to issue AT commands or trigger
other phone functions. The serial line is accessible via the USB cable, as well as via Bluetooth. Once
the link is established, you can access the data of the phone, interact with the user interface and
manipulate the telephony functions.
Serial interface via USB
Once you plug in the phone, the Zaurus will not only recognize the USB storage device, but also
detects the built-in modem. It then should load the appropiate cdc_acm module which brings
support for USB modems and ISDN adaptors. The new device will be placed under /dev/ttyACM0
and /dev/ttyACM1. The devices can be opened with minicom or any other terminal program to gain
access to the phone.
Serial interface via Bluetooth
Instead of relying on a wired connection, you can also use the Bluetooth interface to access this
serial line.
Include the following section in the file /etc/bluetooth/rfcomm.conf:
rfcomm0 {
bind yes;
# MAC address of your phone:
device 00:00:00:00:00:00;
}
Now reload the Bluetooth subsystem with /etc/init.d/bluetooth restart. If you already paired your
computer with your phone, accessing the device /dev/rfcomm0 will instruct RFComm to connect to
the phone without any user action needed. You can monitor the process with the rfcomm utility:
rfcomm
Once a process opens the device file /dev/rfcomm0, the RFComm daemon contacts the phone. See
the bluetooth section for more details.
