Installing C.H.I.P headless

Requirements:  miniUSB cable; C.H.I.P, computer running linux, wireless network.
Optional – Powered USB hub, additional miniUSB cable, computer running Windows.

I recieved my C.H.I.P, but had no spare keyboard, mouse, or monitor.  To get the device configured I did the following:
Download and install Chrome
In chrome, navigate to

I chose Headless 4.4.

If you are on a windows computer, click Install the Driver.  Download and run the installer.


And click Finish.

Click Next

Connect a paperclip, or a 1/2 stripped twist tie to FEL and GND

Connect the C.H.I.P to the computer using a USB cable.

If the flashing fails, disconnect the C.H.I.P.  Close Chrome, and reopen Chrome and navigate to – begin the process again (if you already installed the drivers, you don’t need to install them again)

Once the flash has completed, close Chrome, and remove the paperclip / twist tie jumper.  If necessary – connect the C.H.I.P to the linux computer (used a raspberry pi – it was necessary to use a powered USB hub in order to get the C.H.I.P to have enough power).
Install screen on the linux computer: sudo apt-get install screen

Type the command dmesg | tail

In the output above, you can see the C.H.I.P is presented to the OS as ttyACM1. 
Type the following command: screen /dev/ttyACM1 (replace ttyACM1 with the USB port number from the output of dmesg | tail
If the screen appears blank, press <ENTER>

The default credentials are chip / chip

Type the command sudo nmtui

Authenticate if necessary

Select Activate a Connection

Select your wifi connection from the list and press <ENTER>
Enter your wireless passkey and press <ENTER>

Once connected, you will see an asterisk next to the network you are connected to

Select Quit
type sudo nmtui again

Select Edit a connection

Select your wireless connection and select Edit…

Go to the bottom, and select Automatically connect and Available to all users.

If you wish, open IPv4 Configuration, and manually assign an IP address, Gateway and DNS servers.

Select OK and Quit
Verify you can access the internet.  ping
CTRL-C to finish the ping.

Run the command sudo apt-get update to update the package list
Run the command sudo apt-get dist-upgrade
Select ‘Y’ to continue if prompted.
This may take some time.
Once completed, uninstall group-bin and configuration files
sudo apt-get purge cgroup-bin
It may / may not have anything to uninstall.  This can prevent the unit from booting.
Change the name of the device
sudo nano /etc/hostname
CTRL-X, Y and <Enter> to save the name
sudo nano /etc/hosts
Change the line     chip
to     <new name of the device>
CTRL-X, Y and <Enter> to save the name
Reboot the unit with
sudo reboot
you shuld now be able to connect to the chip with SSH via wifi.
