Please find below the various piece of code that together control my RGB light to loop in Rainbow.
Every two seconds, it change from one colour to another based on the value of the second.
So it compute 30 differents RGB value in a "circle", all with the same Saturation and Brightness both forced to 1.0
The transition from one colour to another is done in one seconds.

The name of my Tradfri RGB light bulb is "light.couleur"

In this configuration, DHCP will run on the OpenWrt Box, while the TFTP server (the one serves the boot files) runs on a different computer.

1. Add to /etc/config/dhcp on OpenWrt Box

config boot linux
        option filename 'pxelinux.0'
        option serveraddress '192.168.?.?'
        option servername '?'
