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. https://stevesnoderedguide.com/understanding-buffers-node-red 73 Dave wo2x ? ?

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. On Wed, Dec 21, 2022, 4:08 PM Kyle K <kylekrieg@...> wrote:

Injecting a Hex Value
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???73 Kyle AA0Z |

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. ? 73’ Thomas and Timon PA1M & PA1T ? ? |

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. 73" Ben Den man. 19. dec. 2022 kl. 15.06 skrev Dave wo2x <RocketNJ@...>:

Re: How to change default name for FTDI USB serial node to use cable ID
开云体育The EA4TX boxes probably do not have genuine FTDI chipsets in them. Either a different chip that does not have unique serial numbers or Chinese clones of FTDI.?This is an issue with some USB to serial converters you buy from eBay and Amazon. They close an FTDI chip and all the closes have no serial number or the same serial number. Prolific chipsets also do not have unique serial numbers.? If you ever reboot the api and wind up controlling the wrong rotor, you’ll know why.? 73 Dave wo2x Sent from my waxed string and tin cans.? On Dec 19, 2022, at 8:53 AM, Kyle K <kylekrieg@...> wrote:

Re: How to change default name for FTDI USB serial node to use cable ID
Thanks to Dave for putting out that video.? I'm going to use it on my RCS-4 replacement flow I'm starting.??
...but another question now has emerged on another project that I did some digging around in. I got to looking at my pi in the amp rack that has a couple of EA4TX boxes (2x6 pack antenna & tail twister rotator) control.?? I'm using ser2net to send the serial data over the network to another pi running Node Red, so the Pi in the amp rack is basically a serial to network media converter. Works great.?? In the /dev/by-id folder, I only see 1 of my EA4TX boxes. pi@elayerrack:/dev/serial/by-id $ ls -lah

How to change default name for FTDI USB serial node to use cable ID
开云体育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. ? 73 Dave wo2x ? |

Re: RCS-4 Antenna Switch Replacement - WA4MCM Remote Switch
开云体育Windows will remember and reserve the com port number for FTDI chipset USB devices based on the serial number in the chipset in the FTDI USB interface.?In Linux as a default the TTYUSB ports are enumerated in the order they are plugged in and leads to possible issues using the default name. I like to use the ID of the USB device in the serial node so it always uses the correct cable or interface, no matter the order they are enumerated.? One of the videos on my YouTube channel shows how to get the ID and how to set up the serial node. I should do a new video and condense it down to just this topic. It would help people new to Node Red.? 73 Dave wo2x Sent from my waxed string and tin cans.? On Dec 18, 2022, at 7:05 PM, Kyle K <kylekrieg@...> wrote:
