The fog and confusion of Node-red and a Nubie
Well, my world is slowing down and I am finding I am having more time to use my Flex 6600m radio. The more I use it the more I am loving it, more than ever. About a year ago I added a 2x8 Antenna Genius and a Rotor Genius. All making a much better station. My problem is that I am really starting to fill up the computer screen with apps, and widgets, not to mention the SmartSDR and Ham Radio Deluxe and a digital program if that is what you are doing. With the M model I can eliminate SmartSDR and run the controls on the radio face and free up some room on the monitor. With all that said I think Node-Red could be my answer.
I have started again with my Raspberry Pi 4b and the most recent version of the Rspi OS and Node-Red v 3.0.1 along with some of the flows that many FlexRadio operators have posted on various web sites. These flows are very well put together and I have had good luck getting them to work on my setup after a few people answered a few earlier questions.
The biggest issue I have now is how to shut everything down and not lose the information. Yesterday I had Davide's FlexRadio flow running very well along with the 2x8 AG flow working, dashboards looked nice, and I decided it was time to move the RP to its more permanent home. I went to the terminal window I had running and found the RP was showing an error on the web address for the Antenna Genius. and was repeating fast enough that I could not get the Node-red stop command input to the system. out of despair I opened an additional terminal and got everything shut down, I relocated the RP hooked it all up and after the RP booted, I restarted Node-Red and went back to my radio bench to run node-Red from there, Node-Red came up and I changed the address for the AG, deployed the flow and clicked to display the Dashboard. the only thing that was displayed was the Mic output, everything else was awol.
What is the proper way to shutdown Node-Red and the RP os? Also, I need to know if I have everything installed properly on the Raspberry Pi, should it be run globally or local ? mine is Local. I am not sure about headless vs with header? I think mine is installed Leaderless.
I would really like to hear from some of you that have become very familiar with Node-Red, I welcome input and comments from all.
