Connecting Raspberry Pi With Arduino using Bluetooth

[TIR]

This is the setup

I have Raspberry Pi with USB BT dongle. I have installed bluetooth and the service is up.

Code: Select all

hcitool scan
Scanning ...
        00:12:05:11:92:75       linvor

This is the rfcomm file

Code: Select all

root@raspberrypi:/home/pi# cat /etc/bluetooth/rfcomm.conf
#
# RFCOMM configuration file.
#

rfcomm0 {
        # Automatically bind the device at startup
        bind no;

        # Bluetooth address of the device
        device 00:12:05:11:92:75;

        # RFCOMM channel for the connection
        channel 1;

        # Description of the connection
        comment "Linvor Bluetooth Device";
}

But when i try to connect to the device i get:

Code: Select all

root@raspberrypi:/home/pi# rfcomm connect 0
Can't connect RFCOMM socket: Connection refused

The Linvor has passkey of 1234. Where should i entered it? There is no more hcid.conf.

Code: Select all

root@raspberrypi:/home/pi# ls /etc/bluetooth/
audio.conf  main.conf     proximity.conf  serial.conf
input.conf  network.conf  rfcomm.conf

The os is Raspbian “wheezy”

I think you need this command:

Code: Select all

echo "1234" | bluez-simple-agent hci0 [MAC_ADDRESS]

[tsh]

Another one struggling with this. I can connect using blueman-manager, but I'm trying to get a command line setup working, and getting nowhere fast...

I have to edit /etc/bluetooth/rfcomm.conf, and got some odd syntax errors at first. I ended up cut/pasting the whole file and replacing with my address.

To set the pairing code, I used

Code: Select all

sudo bluetooth-agent 1234 00:12:6F:20:FB:50
