Wifi acces point on Beaglebone with DHCP

With the OS of Debian new opportunities have come. The Angstrom distribution did not meet our requirements because conman and ROS was not supported well yet, while Ubuntu didn’t have PWM, so that’s how Debian came into picture. The idea of connecting to the BeagleBone directly is better then connecting through some middle layer (like a router). To be this simple we need to config an acces point on the BeagleBone.

Since now we have the wifi working, continuing the effort of last time we finally got to do the next assembly step.

Mounting the BeagleBone on the rover.

It was no big deal.

4 screws to fix the BeagleBone onto the plastic board, some tape for a USB hub and some ideas to hide those way too long USB cables somewhere.

The camera is just for prank, we will have to think of a place to put it, and also a way to hide it’s cable.

Important note: This steps were validated on the following Angström version:


The difference between this and the previous tutorial is that in the new version of Angström they introduced a light-weight network manager daemon called connman. On one hand this makes things easier but on the other hand it renders all the old tutorials unusable.

To see how to get your hardware running with the BeagleBone read this tutorial:

Building a Rover project day 5 – info about your wifi hardware

This short article is describing how to set up a new wifi stick for the BeagleBone running the Angström linux distribution.

Plug your BeagleBone, connect to it and also plug the wifi stick.

Let’s see what do you have:

root@beaglebone:~# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0ace:1211 ZyDAS 802.11bg
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Those 2 hexa numbers are already enough information to determine which driver to use with the stick.

They are called vendor and product id.

Important note: This steps were validated on the following Angström version:


For later versions the classic Linux utilities are controlled by connman so this tutorial will fail to work.

So we managed to set up the cheap wifi stick. I have no idea about it’s name,  the chipset is ZyDas1211.

If you are unsure what chipset your wifi stick has, open it up and check the chip.

Building a Rover project day 1

Continuing yesterday’s work Árpi moved out to do some shopping for heat-sensors and a wifi-stick for the BeagleBone.
I did some the code for the Arduino which is basically a command interpreter based on the code of the OpenROV project.


We successfully mounted the servo motor that does the steering and experimented with drilling an extra hole into one of those metal builder parts to shorten the steering axis – no good yet.
