This page explains how to create an image with enabled Bluetooth.
Current images with BT enabled
- bluetooth-0.1.0.ndz built on baseline-1.0.9.nzd with old madwifi and kernel 2.6.12
- bluetooth-0.1.1.ndz built on baseline-1.0.9.nzd with old madwifi and kernel 2.6.12
The reason to keep this is that madwifi allows to change transmit power. Version 0.1.1 contains old madwifi with ability to fix transmission rate using iwconfig, but does not support libmac To Do: USB Bluetooth key chain has to be reinserted in order to be recognized.
- 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
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.
