Linux under the use of Bluetooth __linux

1. Activating the device

The first thing to have is a Bluetooth adapter, which, needless to say, is typically a USB interface type.

Lsusb               View the Bluetooth devices connected in the system
hciconfig           View the details of the device
Hciconfig hci0 up   to activate the device

2. Configure BlueZ

Configuration file is located in directory/etc/bluetooth 3. Bluetooth Services

/etc/rc.d/init.d/bluetooth Stop
/etc/rc.d/init.d/bluetooth start

4. Scanning Equipment

Hcitool Scan

Use the above command to find the surrounding Bluetooth devices
5. Binding Devices

There are two ways to bind the destination Bluetooth device
@1 Modify/etc/bluetooth/rfcomm.conf
@2 Rfcomm bind/dev/rfcomm0 XX:XX:XX:XX:XX:XX

The Unbind method is
# Rfcomm UNBIND/DEV/RFCOMM0 bd_addr Channel

Tip: If you do not have a virtual serial device (RFCOMM0), you need to create it manually (Rfcomm_create_dev?)

# MKNOD/DEV/RFCOMM0 C 216 1
# chmod 666/DEV/RFCOMM0

6. Add Channel

Sdptool add--channel=1 DID SP DUN LAN FAX opush FTP HS HF SAP NAP GN panu HID CIP CTP a2src a2snk SYNCML nokid pcsuite SR 1

The following parameters represent all the services supported by the system
7. Connecting Equipment

Hcitool cc XX:XX:XX:XX:XX:XX

8. Send the file

Obex-send *.*
