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…

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.…
