Systemd was designed to unify service configurations across Linux distributions. There are several ways that one could schedule a task to run on Linux. How do I do that? By making it a service. I needed for this program to start automatically after the device was powered on and to keep running. This could be useful on my Pis also I run many of them as headless units. I made a program that would let the Jetson’s announce their presence over UDP Multicast. On some other networks I may not have access to the router settings. That approach is fine when I’m using the Jetsons from my house I have complete access to the Network here. Reading the documentation from Seeed Studio, they suggest logging into your router and finding the IP addresses there. Despite the Jetsons being in the same box, they don’t have an immediate way to know about each other. It contains a 5-port switch so that a single Network cable can be used to connect all of the modules. Really the Jetson Mate is just a convenient way to power multiple Jetsons and connect them to a wired network. Up to 4 modules can be placed within the Jetson mate to form a cluster.
The Jetson Mate is an accessory for the Jetson Nano or Jetson Xavier NX Modules. We want to run this script automatically when booting the system, and let it running forever.I have a Jetson Mate. This service will send an IFTTT notification to the configured smartphone containing the Raspberry’s Pi temperature when this is greater than a certain value. In this example we will create a service that monitors the Raspberry temperature. Monitoring Raspberry temperature with a service Its primary purpose is to initialise, manage and track system services and daemons, both during start-up and while the system is running. It includes a collection of tools for a range of different tasks. Systemd is an init system used in Linux distributions to bootstrap the user space and to manage system processes after booting. However, if you want to create a Raspberry Pi service that runs at boot time, considers dependencies and keeps on running in the background, you should use systemd. You can also configure crontab to run the script every X minutes. You can, for instance, use the nickname in crontab in order to launch an script after rebooting your machine. There are several ways to execute a piece of code when your Raspberry Pi boots. 2.1 Monitoring Raspberry temperature with a service.
