Thanks, Al

Yes, I knew someone had made a gate-based client selector, but I could not recall.

Bret has installed my Dynamic Flex Node version and reports it works very well.

If you get a chance, could you take a look?

Just a thought, ?if I start NR ?then open SmartSDR , the flows only show connected, the client (my call) does not work. ?I do a refresh on the browser and NR restart , still no good windows 10 .?
But if I start the radio and SmartSDR first then ?start NR all works great, my call is there also, now If I connect via iPhone and desktop, that does not work ? ?Flex 6600 3.3 version.
I tried doing a start up Node , timestamp node ?

If interested in troubleshooting I can take video with the process.

Re: Injecting a Hex Value

 

开云体育

Looks like your flows is expecting a line feed on input as Chris mentioned. Taking a look at the manual for the controller it appears you send a two byte word and get ?a two byte answer, so you might need to change the input to a fixed length of the two byte word.

?

Here’s a link on working with buffers. You can follow the examples to inject the ASCII A? and have it converted to a buffer before being sent to the controller. The response should be Ax where x is the actual antenna number.

I've been working on this WA4MCM controller and have a few issues.? Hopefully someone can help me.? After installing a new USB port on the back of the unit and the PI actually seeing the unit, now I'm to the point of trying to get data out of it.?

I've got the flow basically written, but I'm having issues injecting a hex value into the device as it's not responding.

Device says it's connected, and I'm using "by-id" full path per Dave's video tutorial.?







Here is the info on the Hex values.



I'm injecting the following with no luck.

A string (A?)




A buffered Hex




String of hex values?



Tried converting the sting to hex and injecting.? Still nothing.??

const bufferText = Buffer.from('A?', 'utf8')

const text = bufferText.toString('hex')

msg.payload = text

return msg;


Any ideas on what I might be doing wrong???

Re: Injecting a Hex Value

 

I'm not sure, but here is a thought. Is the serial receive node waiting for the split char? It looks like '\n' is configured but the protocol doesn't send a newline.

Streamdeck halts after several pushes on the buttons

 

开云体育

Hi,

?

We are having problems with the combination Stream Deck XL and Node Red on a Raspberry Pi 3b.

We like to use the Stream Deck? to select beverage receive antennas and a 9 circle array.

?

The Raspberry Pi has in our test situation 8 relays on GPIO ports and each relay a has a switch in Node red.

To have it working with the Stream Deck ?each of these 8 switches has an http-in node and a Change node to set the Payload to 1.

?

On the Stream Deck using the website plugin (GET request in background) which switches the relays fine. Works also fine when using the Rest Call 1.2 plugin. Pushing a button on the Stream Deck or the switch on my PC screen switches the relays fine.

For this to work I used example flows from Alan. There is no feedback to the Stream Deck.

?

The problem is that after switching (every second) between the buttons on the Stream Deck accessing the relays (through Node Red) it stops working after 12 times pushing a button when using the website plugin on the Stream Deck. Even quicker when using the Rest call plugin. Then it becomes slow after 5 or 6 buttons pushes and the Stream Deck halts.

?

The switches in Node Red on the screen still work fine and pushing them a 100 times does not give any problem. When the Stream Deck halts I do not see using a Debug node anything coming in anymore from the Stream Deck.

Making it all work again I change the Profile on the Stream Deck to another one and switch back and all is fine again for a few pushes.

?

Updated the Stream Deck to the latest firmware (1.01) and software(6.0.1.17732).

The utilization of the Stream Deck seldom goes higher the 10-15%.

?

Anyone any idea how to solve this. What to check.

?

Looks like a Stream Deck problem but no clue what I’m doing wrong or how to solve this.

?

Your help is very much appreciated.

Hi All,

I did a quick YouTube video on how to change the default FTDI based USB serial node name from /dev/TTYUSB0 to the path by ID name which includes the FTDI cable/device serial number. This is unique for each FTDI interface.

?

The order you plug FTDI USB to serial cables in to a Raspberry Pi running Node Red will determine the default name, so if you have multiple USB to serial cables it is possible to have the wrong device connected to a flow. By using the By ID path for the serial node it will ensure the flow always uses the proper cable.

?

Here’s a link to the video. As of the writing of this post the video is still rendering to HD. The HD rendering should be completed soon.

Re: How to change default name for FTDI USB serial node to use cable ID

 

HI Dave

I am sitting here with some problem whit ser2net there will not recognize my usb port ?? a new version of net2ser need a YAML config file and that is out of my range to figure it out ;-) sadly this has worked before but I cant rember how I did it last time ;-)

but I have try your solution where I go in to the file browser in my ubuntu pc /dev/serial/by-id and copy the path of the usb

/dev/serial/by-id/usb-Arduino__www.arduino.cc__0042_85534313837351F0C180-if00

but it will not use the path to show the way to my usb ???

it is a arduino board , but when I use the Arduino node I can get in contact whit the board ...no problem.
