SmartSDR TCP/IP API - Starting demodulation and receiver using telnet
my studies about TCP/IP API are going on, and now I can easily connect my Flex 6300 and tune the slice (using something like C12|slice t 0 14.035).
Everything works fine if SSDR is already running, but now I want to go over: I would like to start the receiver when SSDR (and all its related software) is off.
When SSDR is turned off my client can still connect the rig and tune the slice but I can't hear anything.
To start the receiver I have to remove the slice and its pan (C22|slice r 0 - C23|display pan r 0x40000000) and then create them from scratch (C24|display pan c 14.008000 1 800 400 - C25|slice c 14.009 1 cw). At this point the receiver magically starts.
I am wondering if there is another way to start the receiver using the slice that is already created after the connection.
Sure I am missing something, can you help me?
Thanks you very much

Enzo,
You don't have to create a pan adaptor before creating a slice...c2|sub slice all
R2|0|
Just create the slice and the audio stream begins from the radio.

Note that you do need to provide the antenna port for the slice as a string compatible with the create slice command. These are show in ant_list under the slice information.
Stu K6TU0 -
Thank you very much Stu,
about the antenna ID I was mislead from wiki docs, it reports the command "slice c" with the antenna ID and not with the antenna name, but in my Wireshark logs I have the correct command.
Sorry for my mistake.
If I can, I would tell you about other doubts:
1- just after the connection (when SSDR is off) the command "sub slice all" give me an already created slice (sorry for my poor english); I think the Flex restore it from its previous saved state. In theory, at this point, I should already have to listen to the radio but it doesn't happen.
Actually for me is not clear what really happens when the rig is just turned on and the "first" client connects to it. It should be helpful trying to define a correct sequence diagram.
2- the second doubt is also related to the above question: what is the correct way to disconnect from a Flex 6000? I noted that when SSDR is turned off my client receive some S0| status packets.
3- does the Flex save the status for each connected client? It could recognize the client from the name passed with the command "client program <name>". Or do I have to use the "client start_persistence " command?
73' Enzo IW7DMH0 -
Enzo,
Comments on your questions (and of course, some of my own!).
1. What version of software are you running? I am currently testing an alpha release but I don't see the behavior you describe. When I issue the command "sub slice all" on a radio, there is no active slice and the radio status shows 8 available slices and 8 pan adapters - this is on a 6700.
2. When you close SmartSDR thin client, it will remove all slices it has created. When the last slice is removed, there is no more audio output. So I think the answer to your question is "it depends" - if you want output to the radio to continue, create the slice(s) from your own application and then you get to decide what is the appropriate behavior.
3. No - status is across all connected clients and is identical for all. The radio currently only recognizes one client and that is SmartSDR. Sending anything other string in results in an error message from the radio. If you identify as SmartSDR, the radio will only permit one client identifying with that name to connect at a time.
Stu K6TU0 -
Very well dear Stu,
I repeated three more times my tests and the behavior is exactly what you described on point 1)
On the contrary, what I wrote is what it happens when my console starts and SSDR is already running.
About point 2 and 3 now it is very clear what happens in the startup process.
Today I setted a milestone on my kidding project and I like to share it with you (also to confirm that your patience and efforts were not wasted
Thank you very much

Great work Enzo. I am trying to learn how to do control with an Arduino and am struggling. Looks like you have cracked it.

Oh thank you very much Nigel.
It is still a work in progress and now it is mostly a matter of parsing strings along TCP/IP connection.
I come from Java world (SJCP) and my C/C++ code is not still so good to share it. I am not very proud of it, even if it seems is working very well.
For my project I had to use an Arduino Due as it has a very fast and powerful Arm processor. It has also 512 Mb of memory for your program and about 128 Mb memory of data space.
Also, you need to use the "official" Ethernet shield. Clone shields have poor libraries and if you use them, probably you will lost your time as it happened to me. Official shield has a 100Mbs speed, not so bad for a microcontroller project.
Look for my other posts in the community and you can find all informations that Stu gave me to take the full control over the Rig. Start from there.
The to-do list I followed is here:
1- getting ip address using dhcp;
2- start searching for Flex rigs over the network (discovering protocol);
3- connecting to the rig you discovered in step 2;
4- getting the initial status of the rig (it could be already on) and start knowing all objects you can find; https://community.flexradio.com/flexradio/topics/smartsdr-tcp-ip-api-exaustive-command-list-request
5- start changing the status of the rig (command protocol)
6- .... more to came
My original idea was a DIY, plug and play, console that could work away from any operating system. It seems against Flex philosophy but the TCP/IP API make it possible. I love the silent receiver of my 6300 and I like listening without "bell and whistle", just turn on and listen.

Great work! I'm interested in doing something similar. Where did you find that nice weighted knob?0
-
Well I am doing the same although im only using an Uno with a real Ethernet shield(as you suggested) I have got it to connect, display the version and handle on a character LCD and been able to send commands.
But like you I need to be able to do that from a cold 6300 ie do the auto detect.
anyone wanting the sketch is welcome to it... its actually quite easy to get it going!

Well Nigel, so you are already on step 3 and you are missing the step 2.
Try to adapt the following code. It starts in the setup procedure and you have to simulate a main loop until you find a Flex rig.
Before take a look at the UPD packet structure https://community.flexradio.com/flexradio/topics/wireshark-suggested-filters .
Somewhere Stu said you can find two different length in Flex UDP packets, but I can't find that post. Anyway I choose to handle the one with 156 byte lenght.
I hope this can help.

It comes from the "audio" world: http://www.audioselection.it/product.php~idx~~~3008~~4421ALUB~.html
Non a perfect grip but perfect wheight.
The encoder comes from Ebay (search for "High resolution optical rotary encoder for DDS module VFO etc. 400 pulses/rev")
It is perfect for vfo usage and it doesn't need to be debounced.

Many thanks Enzo. I took your code and ran with it! I Arduino Uno'ed it!! and I will post below.
It uses an Arduino R3 with a "real" Ethernet shield and an Adafruit I2C LCD and buttons shield. some output is on the LCD while debug info is in the serial port.
I am going to move to the Mega and use a 7" 800x480 colour LCD with touch screen saves on buttons!!!.

Very well Nigel!
Consider you have to implement a very powerful text parser and you need a lot of cpu speed and a lot of memory.
That is the reason I moved to a Due board. For the console you can see in my video, I choose these components http://www.sainsmart.com/sainsmart-due-5-lcd-touch-panel-sd-card-slot-tft-lcd-shield-kit-for-arduino.html and eight rotary encoder with embedded push-button.
Using a Due I hope I can move (but don't know when) to a Udoo platform (http://www.udoo.org/ )

Well Enzo, I looked ... liked and purchased an UDOO (quad) and WOW! both Android and Linux worked out of the box I've stuck to the linux as the Arduino IDE is easy on the linux version.
PS i was surprised at how fast the UDOO shipped.
Nigel0 -
Well done Nigel, Udoo platform is really amazing.
At the end of my Due tests I'll follow you

Here are some improvements: now my Flex can be used without a personal computer.
It would be nice having a feature for setting up fixed IP address so you don't need a router when the client is a very basic one like the Arduino boards.
