Your script can deal with working directory, and not outputting to terminal if that's what you wish. Then you simply . . . systemctl daemon-reload systemctl enable <service name> --now Making sure that service-name.service exists in /lib/systemd/system/ As far as what target you need, well that I don't know. I have no clue what an IMU *is* in the context of Nodered, and no idea what you're trying to do. However, if you need your service to run, and all it requires is a network to be established. The above should work. On Sat, Jan 21, 2017 at 1:32 PM, Richard Maurer <[email protected]> wrote: Yup, been all over searches for systemd, and tried different options.

But just google: "how to systemd" + <whichever search term you need> and you'll probably be greated by way more hits than you'll ever need.

It's working nearly exactly as I want except that I seem to be unable to establish a service on the BBG wireless (needed to execute a .py program to run an IMU. It's giving me a The unit files have no installation config (WantedBy, RequiredBy, Also, Alias....error when I try to enable the service. Not sure why, as I was able to enable the Nodered service, using their code and installation guide. I've seen a number of recent similar errors that have been reported in bug reports, so I might be doing the installation correctly, but just can't figure out what is different in the node-red service. Anyway thanks for the inputs, offers, and suggestions. On Thu, Jan 12, 2017 at 1:35 PM, TJF <[email protected]> wrote: Am Donnerstag, 12.

It's plug-and-play when you spend a few further bugs and buy a developers board like nodeMCU. You plug in the USB, start a terminal and you'll also see what's going on with it in the Lua interpreter. For my engineers mind, this solution will provide faster results. You can focus on the necessary features and use a lot of-the-shelf features. Anyway, it's your decision. Good luck for your project. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to a topic in the Google Groups "BeagleBoard" group.
