When running linux, you sometimes want to connect to a cell phone (using it as a modem) over bluetooth.<\/p>\n

Different cell phones use different RFCOMM channels to export their Dial-up Networking service on.<\/p>\n

Here are the commands to use to find which channel you should use:<\/p>\n

hcitool scan<\/strong> – This command gives you a list of all the bluetooth devices in the area, and their associated BDADDR's. Look for your phone, and note the BDADDR.<\/p>\n

sdptool search –bdaddr <YOUR_BDADDR> DUN <\/strong>– This command will return the correct channel to use, with a result something like this:<\/p>\n

Service Name: QC Dial-up Networking <\/code><\/font><\/pre>\n
Service RecHandle: 0x10007 <\/code><\/font><\/pre>\n
Service Class ID List:   "Dialup Networking" (0x1103) <\/code><\/font><\/pre>\n
Protocol Descriptor List:   "L2CAP" (0x0100)   "RFCOMM" (0x0003)     <\/code><\/font><\/pre>\n
Channel: 8 <\/code><\/font><\/pre>\n
 Then you can set up an rfcomm.conf file as follows (Note the use of Channel eight):<\/p>\n
 rfcomm0 {         <\/code><\/font><\/pre>\n
# Automatically bind the device at startup         <\/code><\/font><\/pre>\n
bind yes;          <\/code><\/font><\/pre>\n
#LG CU500         <\/code><\/font><\/pre>\n
device  00:19:A1:51:1D:FC;         <\/code><\/font><\/pre>\n
channel 8;           <\/code><\/font><\/pre>\n
# Description of the connection         <\/code><\/font><\/pre>\n
