David:

Last night (on the 6400's flow) I had the S-meter zeroing when no one was connected to the 6400 just fine. I used this Function statement to set the meter to -120dBm if the "ClientStatus" was not 1. See what I used below:

It was working like a charm yesterday.

Tonight, when I disconnected from the rig, the S-meter pegged again.? So, I went to the Flex v6 flow to see what the output of this node was


(I think it should return a "0" if no client is connected) but there is NO payload returned. Any idea what could have changed?

I *did* get the 6400's dashboard pretty well done.?



Most of the problems Im having with the 3000 is that the serial connection over TCP only sends the responses every second or so, which causes problems using the returns for gating other things.

I'll keep at it. It is a good mental exercise. I am getting better, but still lots to learn.

Ok we’ll do it sometime this week. I am working on my Node Red presentation for the QSO Today virtual ham fest in a couple of weeks. Need to get it finished.?

Dave:

I'd love to do that sometime this weekend if you have time. I've been playing with this all day.

That is what I was trying to say......that THIS:


? ? ?EQUALS THIS ==>? ?

to me.... ha ha ha.??

I'm trying to see what goes inside of the nodes when you double click on them.?

Charlie KB8CR?

The Format node worked to make the command I wanted, but apparently the radio isn't taking the command thru the TCP port.
I wonder how HRD gets everything to work by serial port. ha ha

Both the function nose and the change node are good methods. ?Just expanding the Change Node to include additional added text.

I revised the change node to include text in front and following the msg.payload. ?Also combined with gate components. ?JSON code follows:

In his case it is text + msg.payload + text so function Node as I outlined is easiest

Charlie

Lots of methods to build a string, but, staying with the "Change Node" to build a string with text added to the msg.payload, use the Jasonata code method:




Here is the JSON for above:

Use a function node

Charlie

Here is an example of a flow, using the "gate" node, triggered on TX>closed, and RX>open. ?Also, I have circled where you can get help on any node you select on the editor. ?Also, below is the JSON code for the example gate flow.

Alan:

Yea....I was just playing with it, but it isn't worth all this.....runs fine on my Pi's. ha ha.

I do have a quick question, if that's ok..... I'm trying to insert the output of one node (which outputs a number) into the middle of another string.
I tried using a change node, and SET the msg.payload as xxxOUTPUTOFTHEPRIORNODExxx

I've tried putting {{msg.payload}}, {msg.payload}, (msg.payload) and some other attempts to insert it, but none work.....I just don't know what syntax to use.



The ZZGT is the command to change the AGC on the rig, and the trailing ; is the command end.? The prior node outputs a number. I'm trying to use the drop-down list to change AGC, and it outputs that number fine (using debug) but I don't know how to name it in the change node.

Dave:

While I have the meters in for the 6400's flow zeroing fine, the same isn't the case for the 3000.

I can't figure out the GATE node....Can't find any examples that don't just show the pasted "code" which I don't know how to look thru.

I tried using a Function node and write a if/else statement (unsuccessfully....hi hi) using the TX/RX status that I have from the 3000. I even tried making a global.RXTX that I could use....no joy.

I think part of the problem, is that for the FWD PWR and SWR meters, the serial data is not sent at all until it's in transmit. As such, the meters just show the last data it DID get, while it was in transmit. I tried configuring the switch node that uses regex looking for ZZRM5 (which is returned with FWD PWR) or ZZRM8 for SWR, and then add an OTHERWISE option, connecting that to a Change node to set the payload to "0". When I tried that it would pulse up and down....???

Any links to how to use the gate node?

Charlie

Tried it on a different computer.....same result.

Charlie

Also, if clearing the browser's Cache does not allow you to see the Dashboard, can your try another browser? ?Or, even a different computer?
