Adding the Wi-Pi WiFi Dongle to the RIoT Android Board

Address your IoT software testing needs – improve quality, security, safety, and compliance across the development lifecycle.

The wired Ethernet connectivity works out of the box with the Freescale RIoT board. But to make it more ‘IoT’ capable, a WiFi connection would be a big plus. The element14 site did not tell which WiFi dongles are supported, and a thread in the element14 forum on that topic has not really provided much information. With some risks I decided to order the Wi-Pi WiFi dongle which seems to be popular in the Raspberry Pi community (thus that Wi-Pi name?). And as I anyway have a Raspy, my thinking was that if it does not work with the RIoT board, I still can use it with the Raspy.

The Wi-Pi WiFi USB dongle is available from multiple sources, including Farnell (part number 2133900). The dongle comes in a tiny card box:

The USB dongle is around 35 mm long so it does not much space:

Need to Update Android

I was not able to get the Wi-Pi working with the original Android image (SVN2515) on the board. With installing SVN2597 the Wi-Pi dongle worked.

Configuration

To configure the Wi-Pi, go to the Android settings:

Android Settings

Android Settings

Then turn Wi-Fi on:

Enable WiFi

Enable WiFi

:idea: If (hopefully!) using any encryption/WPA/etc, you are prompted to enter the password. It worked fine for my WPA2 wireless access point.

The blue LED on the dongle shows that it has connected to the network:

Summary

With the Wi-Pi dongle I have now WiFi capability for the RIoT board, and it works out of the box if using the latest Android version. Another reason to load the latest Android firmware to the RIoT board.
