Connectivity - Using a Bluetooth Dongle

Network Connection

 

A simple way to set up a network connection using a Bluetooth dongle is using the Personal Area Networking (PAN) profile.

 

Load the following modules on i.MX platform:

# modprobe ehci-hcd
# modprobe hci_usb
# modprobe bnep

Set hci0 up:

# hciconfig hci0 up

Check if the hci0 is set by typing:

root@freescale ~$ hciconfig
hci0:  Type: USB
        BD Address: 00:1E:58:3F:4D:09 ACL MTU: 384:8 SCO MTU: 64:8
        UP RUNNING PSCAN ISCAN
        RX bytes:4813491 acl:53228 sco:0 events:208901 errors:0
        TX bytes:156025160 acl:410140 sco:0 commands:83 errors:0

root@freescale ~$ hciconfig hci0 piscan

Start the Bluetooth service:

root@freescale ~$ /etc/rc.d/init.d/bluetooth start

Start the pand service as Pan User (PANU):

root@freescale ~$ pand -s -r PANU

On Host (PC), load bnep module:

$ modprobe bnep

Start the pand service as Group Ad-hoc Network (GN):

$ sudo pand --connect 00:1E:58:3F:4D:09 --service GN -n

The target address (in this case 00:1E:58:3F:4D:09) can be found using hciconfig command on target

 

A BNEP0 network should be created on host (PC) and target (i.MX):

Configure BNEP0 IP on PC:

$ sudo ifconfig bnep0 192.168.0.11

Configure BNEP0 IP on i.MX:

$ ifconfig bnep0 192.168.0.10

Now the PAN network is set. You can test using ping:

root@freescale ~$ ping 192.168.0.11
