Cheap LoRa Gateway using Pi & RAK831

RAK831 LoRa Gateway

Lately, I have been working with LoRAWAN and I don’t have Lora gateway around. As you might be knowing LoRAWAN network requires a gateway to push data to the internet. As Lora is not an IP based protocol the gateway helps it in doing so. Basically, multiple LoRAWAN nodes transmit data to the gateway and the gateway transfers the concentrated data to server backend. Server backend which resides in the cloud contains a network server which helps in managing the network and the application server which is responsible for the data and…

Install Zulu JDK on Ubuntu

ZULU JDK on Ubuntu

Recently I moved my server to Ubuntu from windows. I went with Ubuntu 16.04 server edition as it is lightweight as compared to desktop edition and comes preloaded with some server tools. As I am running OpenHAB for my home automation system I wanted to install it on the server but the server edition doesn’t come with JAVA/JDK pre-installed. As per OpenHAB, Zulu JDK is the recommended JAVA platform and performs better as compared to OpenJDK. Though Oracle JDK can be installed, I thought of trying ZULU. So let’s see…

Access Watchdog Timer of Raspberry Pi using JAVA

This tutorial is all about using the watchdog timer of Raspberry Pi by using JAVA. For this, we are going to use Pi4J library. Watchdog Timer: “A watchdog timer (sometimes called a computer operating properly or COP timer, or simply a watchdog) is an electronic timer that is used to detect and recover from computer malfunctions. During normal operation, the computer regularly resets the watchdog timer to prevent it from elapsing, or “timing out”. If due to a hardware fault or program error, the computer fails to reset the watchdog, the timer will elapse and generate a timeout signal.…

Programming Linkit Smart 7688 DUO using Arduino IDE

Linkit Smart 7688 DUO

In this tutorial, we will see how to program the Atmega324 controller of Linkit Smart 7688 DUO module using the Arduino IDE. The boards come in two flavors, Linkit Smart 7688 and Linkit Smart DUO. The difference between both is that the DUO has an ATMEGA324 controller apart from the main MPU which can be programmed using Arduino. In DUO module GPIOs of both the MPU as well as MCU are exposed and some are even multiplexed. The MCU can also be interfaced or controlled using the MPU but in…

Mongoose OS Installation on ESP8266 and GPIO Access

mongoose OS

This video is around ESP8266 module and how to flash mongoose OS to it.It also demonstrates some basic GPIO programming using javascript.Mongoose OS claims as an Operating System for commercial connected products with features like Security, OTA Updates, Remote Management. As Arduino framework is not reliable to run in production environment its a good alternative with  Arduino compatibility layer that allows using existing Arduino drivers for prototyping. It is both C/C++ ready for production and  JavaScript is for fast prototyping on the target hardware. The JS API calls C API.…

OpenHAB: Installation on Windows for Home Automation

OpenHAB on Windows

OpenHAB is a vendor and technology agnostic open source automation software for making home automation easier. This video is around how to get started with OpenHAB 2. In fact, this is going to be a series of video around it as I have completely shifted towards OpenHAB for my home automation system. Earlier actually I was using my own automation system built on PHP, JAVA, and MongoDB and it was becoming hard for me to manage that and so I thought of getting into already existing automation system and with…
