LoRaWAN on the other hand, is a wireless communication protocol, built on top of LoRa physical layer and designed for long-range, low-power applications such as Internet of Things (IoT) devices. LoRaWAN support 3 different operating modes: Class A, Class B, and Class C. The operating modes determines the communication behavior and power consumption characteristics of LoRaWAN devices.

The hardware platform was based on an ESP32 board. The ESP32 board queries the existing system through a SPI base command interface, and makes the data available over JSON-RPC interface. The mobile application runing on iPhone / Android mobile, queries the data periodically over the JSON-RPC interface, and displays it on the mobile application interface, in a format that is convenient for the user.

This case-study involves, booting all the lab computers over the network, with a Linux kernel and a minimal root filesystem image, using PXE boot. This way each computer did not have to be individually setup. The Tiny Core Linux distribution was used to create a minimal filesystem image, containing the firefox browser.

This article tries to brief the purpose of embedded Linux build systems and introduction to few of the popular ones.
To develop a Linux based embedded systems, it is required to compile the bootloader, kernel, filesystem and applications using script files using custom build procedures. An Embedded Linux Build System refers to the the tools and the environment for building the software packages for a particular board/machine.Read More ➠

This article talks about 4G bring-up from scratch using the OAI code base. The idea is to collate the data available and provide a sequence of instructions that would help bring up a 4G eNB and a 4G UE in a single linux machine, using namespaces.After the setup is up, i.e, when the UE is able to connect to the eNB, the interface is tested by browsing. The results are recorded. Images are added, describing the LTE architecture, for better understanding.Read More ➠
Kivy is a Python-based open-source library for writing GUI applications, for touch-screen based systems. Kivy supports both desktop environments and mobile operating systems like Android and iOS. In our previous article, we talked about porting Kivy to Yocto, on the Colibri T-20. In this article, we demonstrate what Kivy features make it suitable for building UI for handhelds, with the case study of a barcode based asset tracker.

Android applications are the prominent software developed in this era. The developers and testers may want to automate the testing of their App with less learning curve, before getting into a full blown test frameworks. Using ADB commands for Android testing is a lean methodology, where with a few commands and little quirks, the tests can be automated. In this article let’s get to know about the ADB, and few categories of UI features that can be tested with ADB. It would be nice to watch, testing the "GALLERY" App automatically with ADB.
