IOT: Ingesting GPS Data from ODroid XU4 Devices with Apache MiniFi and Python

[#1]

Initial Login to ODroid XU4

GPS Command Line Check

WiFi Signal Strength

Install Ubuntu Extras

Above is our device with GPS

The ODroid XU4 is a powerful little inexpensive IoT device. It is similar to a Raspberry PI and compatible with many of the libraries. I chose to install ARMBIAN Ubuntu which is a good OS. It is very easy to add GPS libraries, Apache MiniFi, JDK 8 and Python for processing.

Software and Device Setup

We need to setup a Swap area to deal with not enough RAM for builds.
