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
