This page explains how to create an image with enabled Bluetooth.

== Current images with BT enabled ==

 * baseline-2.3.ndz with nodeAgent4 detailed [wiki:Documentation/SupportedImages here].

 * bluetooth-0.1.2.ndz built on baseline-1.0.9.nzd with old madwifi and kernel 2.6.12

The reason to keep this is that old madwifi certainly allows to change transmit power.

 * bluetooth-0.2.0.ndz built on baseline-2.0.ndz with hacked nodeAgent to support new madwifi

== Making Bluetooth work ==

The kernel must have USB and Bluetooth support enabled. If that is not the case:

{{{
/usr/src/<path to your kernel source># make menuconfig
}}}

To make USB sticks recognized on boot, select:

  * USB:
{{{
   Device Drivers --->
     <M> USB Support --->
}}} 

  * Bluetooth:
{{{
   Device Drivers --->
     Networking Support --->
       <M> Bluetooth Subsystem Support --->
}}}

Compile the kernel and reboot. There should be /proc/bus/usb directory created.

{{{
apt-get install bluetooth
/etc/init.d/bluetooth start
}}}

After that you should be able to see something like:
{{{
node1-1:~# hciconfig
hci0:   Type: USB
        BD Address: 00:0A:3A:53:D4:82 ACL MTU: 192:8 SCO MTU: 64:8
        UP RUNNING PSCAN ISCAN 
        RX bytes:395 acl:0 sco:0 events:17 errors:0
        TX bytes:313 acl:0 sco:0 commands:16 errors:0
}}}

In order to save the image, and be able to login to the node by means other than the serial console delete the following file if exists:

{{{
node1-1:/etc/udev/rules.d# rm z25_persistent-net.rules
}}}

Otherwise, saving an image causes the interfaces to "shift" from eth0 and eth1 to eth2 and eth3, and the node is after imaging accessible only through the serial console.
