By the way, upgraded to SDR 3.17 and all went smooth. Everything including Maestro and multiple third-party apps worked out of the box. W10 running on Mac Parallels. Nice!
Here is a screenshot of my LEO Satellite Tracking Screen. I was previously using my iPhone Home Kit to control the antenna selection, pre-amps and polarity. Now, using Node-Red, I have an on-screen antenna control panel. Nice.
The new antenna control panel is on the right, just below Smart SDR.
The shack is in the house about 200 feet from where all of the radio and antennas are located, so remote control over the LAN is a "must" need.
Now, working on a monitor panel for the server cabinet containing all of the radios and auxiliary equipment. The server cabinet is in a somewhat dusty environment, so I have a fan configuration to regulate air temperature while keeping a slight positive pressure inside for dust containment. Present controls are analog and I do not plan to change. Just want to monitor in case something fails.
The Flex API remains a mystery to me.
Will share any of my work products or point you to where got them, just ask.

BTW, if using Chrome for your interface, you can shrink the screen size with zoom in and zoom out. I run mine at 50% but if someone is vision impaired, they could go to 200% as well.

I am in receipt of your flows two weeks ago. Thanks.
Please get well soon. I too had surgery and am in the end stages of recuperation.
Back to the flows.
I was able to get your VITA49 flow working nicely. I see that it receives the UDP broadcasts from port 4992 of the Flex.
I have not been able to get your "flexradio" flow to work. I see that the flow sends a request to the Flex API and looks for a response. You then parse the response into desired parameters for Node-Red to process. Your "flexradio" flow also uses port 4992, same as the VITA49. Is that correct? Node-Red is reporting an error message saying there is a port conflict??
Get well and maybe we can talk more after your recuperation.

They removed the knee joint and installed rods, plates, and cement spacers until the infection is cleared. Could be anywhere from 3 to 12 months.

Currently have a antenna tuner / switch with 24 outputs and FWD/REV power meter, Amplifier controller to my home build PA and a 3x rotor controllers on Wi-Fi.
Working to integrate all the data into a single WEB page for remote control.

I tried to load your flow and only the Dashboard Node was included in the file.

On the "Description" Tab, Flex says, "SmartSDR FlexLib provides access to the SmartSDR TCP and UDP/IP APIs using .NET classes and events."
Can anyone point me to a learning source for the above?
Or....am I in the wrong category for learning how to use Node-Red with the Flex API?

But it's to slow to read and send data in real time.

) onto the command. I use function nodes to send commands to the radio.
Function node to set CW speed:
msg.payload = "C19|cw wpm " +msg.payload +"
";
return msg;
The speed value (0-50) is sent to the function node above via a slider node.
NOTE :
Thanks to Eric at Flex radio to help me understand how to receive certain messages from my radio.
In order to receive and then parse messages you must first subscribe to an object using the Flex Ethernet API.
For example, to receive and parse messages about ALL slice information and changes send the command below to the radio. The messages will then start to flow when changes are made to a slice such as frequency, mode, filters, etc.
msg.payload = "C21|sub slice all
";
return msg;
See the SUB and UNSUB commands in the SmartSDR Ethernet API.

My basic Node-Red dashboard so far...
I am not a "real" programmer but I can now build a cool web interface to my Flex 6600M using Node-Red via the Flex SmartSDR Ethernet API. I've learned allot and had fun doing it !

I will publish my Node-Red code when I'm finished.
I added a 24V FAN to the cabinet running on a 12V circuit. So, next I needed a fan control to turn it on and off. Bam.. I have a thermostat that uses one of the relays in the KMTronic.
I'm still working on smoothing it out. I need to understand how the high and low pass filters work.

If a solution for audio from radio to Android phone can be easily cobbled together then radio control and operation from an Android phone is doable. Don’t get me wrong, it is not going to be a replacement for Marcus’s excellent SmartSDR for IOS but a fun project none the less.
Just a thought.
