How to use bluetooth to transfer data between Neo and Desk-top
This page , we will introduce about , how to active your Neo bluetooth device via host. You can follow these step to learn how to transfer data between Neo and PC.
configure your setting of host
First you should modify this bluetooth setting file in your desk-top computer:
> sudo vi /etc/default/bluetooth
then search for the keyword "/pand" to find " PAND_ENABLED=0 "
And now you should change the 0 into 1
After you modify the setting, use this command to restart bluetooth device.
> sudo /etc/init.d/bluetooth restart
After restarting the bluetooth, you will see Bluetooth PAN daemon information.
That means you wake up the PAN daemon successfully.
After that,you should pass the argument to let PAN daemon know what it should do now.
> sudo pand -s
this command lets a desk-top computer be a server to listen to other Linux-based devices connecting to it through Bluetooth.
On the Neo side
In the Neo:
> echo "1" > /sys/bus/platform/devices/neo1973-pm-bt.0/power_on > echo "0" > /sys/bus/platform/devices/neo1973-pm-bt.0/reset
this command will search nearly bluetooth device.
> hcitool scan
Put the wanted bluetooth's Mac (Address) in this line
> export PC_BT_ID=(bluetooth's Mac) > pand -c $PC_BT_ID --service NAP --autozap
> ifconfig bnep0 10.0.0.2 netmask 255.255.255.0
Switch back to the Desk-top computer :
>sudo ifconfig bnep0 10.0.0.1 netmask 255.255.255.0
This means that desk-top computer will set up environment for connectiog the Neo.
Then, you can use the "ping" command to check whether the connection is build sucessfully or not.
> ping 10.0.0.2
// send the testing data to the Neo
If it works ,you will receive following message:
PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data.
64 bytes from 10.0.0.2: icmp_seq=1 ttl=64 time=xx.x ms 64 bytes from 10.0.0.2: icmp_seq=2 ttl=64 time=xx.x ms 64 bytes from 10.0.0.2: icmp_seq=3 ttl=64 time=xx.x ms
Start to transfer data
Also,you can copy datas to the Neo.
> scp XXX.X firstname.lastname@example.org:
That's all. Enjoy:)
