Right now if you leave any option off the settings.sh command line, it will reset to the defaults at the top of readsettings.sh. (As expected) Need to update settings.sh to sed the /root/temp-settings file instead of recreating it each time. Then we can change only specific items and not wipe previous settings.

the Features of leantrx would be a great Addition to your custom build. would be great if You can allign with the author and add this to your cool Software. More Info could be found here and thanks for considering http://www.pabr.org/radio/leantrx/leantrx.en.html

This would mostly be for WBFM but could be used with anything that plays audio. WBFM is the biggest use-case since its not supported by OpenWebRx.

Current idea = Icecast + ices2
This would allow the output from rx_fm or rx_sdr to be piped into ices2 and then played via the web browser through Icecast.

Its a bit heavy-handed, but not finding any other real solutions to be able present an audio "file" to the browser for easy playback. (I say "file" because it can't be a real file, there's no space, it has to act solely as a stream when fetched.)

Right now you can only update manually by using scp to upload the update.zip to the pluto. Should figure out how to use the mass storage device where the config file resides.

Looking to add a ssh terminal to the site but having trouble finding a basic non over bloated option. We need to find something that requires no install on the pluto just using java or something.

1. Does the settings popup pull the current settings or just use some pre-defined defaults? Can you make it pull the current settings each time if it doesn't already? Not sure how you want to do that, you could cat /root/temp-settings and pull out the values or run /bin/readsettings.sh and pull them from the output. I can help where needed using awk or whatever to strip out the unnecessary stuff.

2. The auto-reboot was changed from 24 hours to 12 hours since I still see if randomly going dark. I need to hook back up the UART to see what the deal is when OTG goes dark. For now, take out the '24h' from the settings page for the reboot and just leave it without a time range for now.

Issue is that unzip on the pluto doesn't support chmod, so if you change perms on an existing file on a pluto, they don't apply unless the files are deleted before running the update. Should be able to change unzip flag, if not, then consider changing to tgz. Latter might be best since its likely tar and gzip will always be part of the image, unlike unzip, which I had to add to the image. (Changing to tgz could save a tiny bit of precious space though.)

Hi,

I cannot get the SoapyRemote to get working on the latest PlutoWeb (v2.7)

Something weird is that the local SoapySDRUtil reports a somewhat unexpected path:

# /bin/SoapySDRUtil --info
######################################################
##     Soapy SDR -- the SDR abstraction library     ##
######################################################

Lib Version: v0.7.0-gd79a09d3
API Version: v0.7.0
ABI Version: v0.7
Install root: /home/steve/Desktop/SDR/Pluto/staging
Search path:  /home/steve/Desktop/SDR/Pluto/staging/lib/SoapySDR/modules0.7 (missing)
No modules found!
Available factories... No factories found!
Available converters...

It seems the paths matches the build environment, not the installed one.

The actual search path would rather be: /lib/SoapySDR/modules0.7

Soapy tools are rather terse about debugging option switches or even configuration option switches.

Is there any FAQ/HOWTO about SoapySDR remote with PlutoWeb, I guess I'm missing something.

It lets you stream/record up to 8 channels of AM or NFM audio within the tunable BW of the RTL-SDR. I would be awesome to be able to do that across the comparatively huge BW of the Pluto. I'd especially be interested in a standalone recorder to a USB OTG thumb drive.

https://github.com/szpajder/RTLSDR-Airband

Upgrade to 0.29 hard float and full recompile - previously compiled pluto bins will NOT run here!

BUT - compiling software to run on the pluto just got easier because of this. You can compile natively on a Raspberry Pi3 using some or all of these compiler options:
-mfloat-abi=hard -march=armv7-a -mtune=cortex-a9 -mfpu=neon -mvectorize-with-neon-quad -Wformat=0 -DNEON_OPTS -funsafe-math-optimizations

• Added retrogram-plutosdr as /bin/retrogram-plutosdr.sh Accepts command line options just the same, simply wrapped it so you don't need the export TERM step.
• Added morfues_tool
• Added gnuplot and libpng
• PlutoWeb UI now has LeanTRX button and top tab/link (button just stops all services so radio is free'd up)
• Updated all SoapySDR components and switched to pathos SoapyPlutoSDR module
• Updated leansdr components
• Updated multimon-ng
• Updated rx_tools

Lean TRX has a power parameter (--power) but it isn't available on the DATV TX web settings.

I can edit a file to change the API key but I cannot save it. It will go back to the original value after reboot. Any option to change to key?

Edit readsettings.sh and savenow.sh so that we create and use a "fw_setenv -s"-compatible /root/temp-settings file instead of writing each variable individually. We also need to use the LED status during nvram saves/erases. Use scripts from buildroot/boards/pluto/update.sh.

Then to integrate with config.txt, piggy-back on buildroot/boards/pluto/S40network and during the creation of config.txt, append the PlutoWeb variables in there as well. Then to support changing them in config.txt and ejecting the device, we'll need to edit buildroot/boards/pluto/update.sh process_ini() function to include the PlutoWeb variables.

Should be pretty easy to take some values (freq range, gain, etc) from a new web page, stop services, run the scan, show the png file right there on the page.

Right now any change to any setting causes settings.sh to restart the running app even when its an unrelated setting.

Test changing from 192.168.2.1 in config.txt and see if things break after a reboot. Test via USB connection and via OTG network. Do openwebrx, dump1090 and SoapyRemote all still work OK? This is RE: jocover/SoapyPlutoSDR#7

What do you think? Rename it? I just called it PlutoWeb without much thought, have an idea for a better name?

Winner is gzip.

and plot data to a map application or pipe gps data out.
https://github.com/rs1729/RS

RS41 is mostly used in Europe.

Can you edit your script to include a no flag for all yes or no options i.e write to nvram, autoupdate....... This will make the web CGI script work for everything. Currently it wants a flag for all settings and this would be the easiest fix.

Add AP mode for wpa_supplicant in zynq_pluto_defconfig.
Edit S40network and set defaults for AP mode SSID, IP, etc
...maybe that's all?...

For some reason every time I extract the update.zip on the pluto the /lib/libSoapSDR library comes out wrong/almost empty..I can unzip fine on my desktop though...strange...this means openwebrx and soapyremote won't work. Maybe there's an 'only update older files' option on unzip on the pluto?

Want to pretty-up the main README.md file? Maybe with some screenshots and/or better instructions on usage? Really needs some better structure I guess.

Done 8427341

Implement a web/cli-based SNA / VNA to allow sweeping antennas and RF filters. A promising route appears to be porting this for the Pluto: http://pavel-demin.github.io/red-pitaya-notes/vna/
Source: https://github.com/pavel-demin/red-pitaya-notes

Referenced: pavel-demin/red-pitaya-notes#808

1. You don't need to include a default settings.txt you created, /bin/readsettings.sh gets called at boot and will create it from the settings it got from nvram.

2. Can we redo the order in your settings.txt file because I'm already using a certain order in several places and keeping this the same would be easier since the order actually matters here. Also, all values will always be lowercase unless its SoapyRemote in which case it will have caps in it. This is because this variable is used to know which program to start so it has to match the name exactly. Also, I use a lowercase y for the autoupdate and autoreboot is now configurable in the number of hours.
   (The list below is just to show order, settings.txt will only contain the actual values.)
   autostart=openwebrx
   autoreboot=12
   autoupdate=y
   center_freq=460250000
   start_freq=460102200
   samp_rate=600000
   start_mod=nfm
   rf_gain=89
   ppm=0

Post the change here once you redo the order, then I'll finish the script.

maybe add a LearnTRX flag to settings.sh so in the future if we can ever pass stuff along to it might make things a bit easier. then I can call that with the CGI file instead of the none flag

Add retrogram-plutosdr to PlutoWeb

This is more of a question than an issue. I've successfully run some python on the early January 2019 PlutoWeb kernel. The new capabilities are great.

However I'm having some trouble running some of the interfaces with PlutoSDR and Gnuradio companion graphs. Which, if any, of the Gnuradio-companion source and sink blocks
work with this version of the PlutoSDR kernel?

Thanks for all your effort.

Best regards
Glen

pothosware/SoapyRemote#37

Hi unixpunk,
glad that I have located your GitHub and see how much nice work you already have done. Maybe there is an interesting feature wish which is easily to do by you but not by me... I am working at a SDR standalone TRX project which uses STM32H7 (or F7) MCU. It is working already very nice using Tayloe mixer front for lower frequencies < 50MHz. But with upcoming Es'Hail it would be very nice to do much more than 50MHz.... Here you can find the project: https://github.com/df8oe/UHSDR Pluto has the capability of covering the "missing frequency range". But it does not have a simple possibility to adapt it to an embedded systems MCU with low RAM, low horse power (comparing to PCs or Raspberry Pis). What is needed is a communication via SPI. I am not sure SPI bus is present on the GPIO headers - that would be nice. Then a simple protocol which allows setting of samplerate (which is coming back to outside) and middle frequency via SPI and get out IQ data stream would allow to drive Pluto with our standalone TRX solution ;) Can you imagine to implement such a SPI interface?

EDIT:
I have investigated: we do have SPI1 bus of Zync on external connections! It is PS_MIO10 (MOSI), PS_MIO11 (MISO), PS_MIO12 (CLK) and PS_MIO13 (CS). 12 is named as UART_TX and 13 as UART_RX at the connectors header of Pluto. So everything would be "ready to go" at hardware side...

Andreas, DF8OE

This way we don't write all variables to nvram unless they've been changed from what is in nvram already.

I'm not yet sure whether it is due to a comm issue from a client, or if may die while being idle, but SoapySDRServer dies sometimes (2 times in a 2 hour timeframe for now).

I think it could be useful to restart it automatically.

Need to add new variables and pass them into config_webrx.py available to be set in config.txt only, to start with at least.

32908cc Done

Hint: mutability/dump1090@6e13727

Also need to update the dump1090 link on the right to point to the PlutoSDR/dump1090 repo: https://github.com/PlutoSDR/dump1090 since this is the fork I used due to it already having been converted from using rtlsdr to libiio/ad9363.

I've been trying to write a custom bit of C-code to detect events in the PlutoSDR data stream.
This would run in the PlutoSDR and write sequences of samples centered on detected
events, time tagged.

For radio astronomy, and particularly cosmic ray detection, it would be fantastic to have
a bit of code watching the PlutoSDR data stream, at wide bandwidth (60 MHz), and would record
rare radio flash events. The duty cycle would not be large, not more than about 1 event a minute,
so the data rate would not be too high. The detection would be based on setting a
threshold number of "sigma" of an event, which would be large, say 10 sigma, so would
never happen for Gaussian distributed noise.

This would also be useful for other Radio research, like detecting 1 PPS pulses, or other
equipment glitches.

Our group of researchers is building a high-school level radio astronomy system, that
would also have a really important key science project, which is very timely,
understanding the cosmic ray background of extreme high energy events. The flashed are created
when extremely high energy cosmic rays hit the earth's atmosphere. The reason
this would be a great project for high schools is that these cosmic ray flashes only cover
a small area, about the size of a football field. So each set of a few telescopes
would be making a unique contribution. These flashes are rare, a few per year, but
with energies thousands of times higher than can be created in the biggest particle
accelerator.

More info is at: https://opensourceradiotelescopes.org/wk

I'm working on a prototype to run inside gnuradio, but the data rate must be
much smaller in Gnuradio.

Our telescope software is at: https://www.github.com/glangsto/gr-nsf

Thanks again for your time and consideration. PlutoWeb is a great advance.

2e943aa README.md: Add note about gcc toolchains

Some suggestions for the PlutoWebUI are:

1. List out all current settings somewhere on the screen or in an overlay from a link, just the text like plutoweb.conf (except without the 'export')

2. The defaults filled in for the settings on the UI should always be the current active settings when you refresh the page, this way if you change only one, it never resets any others.

3. Have the status of (either) which daemon is currently running OR a running/stopped flag next to each daemon (I can help with commands to identify this one or I can make a script that will tell you certain things about the running daemon if you want, like pid and maybe port number?)

4. We should also add a LeanTRX daemon button, but instead of it setting the program to SoapyRemote, it can set it to none instead. (The word none) It can have a link to /leantrx there too.

Changed the main config file name, makes more sense this way, especially once you can download it from the webUI. 13f8e54

It sets the autostart=<null/nothing?> Script isn't handling it properly. Guessing this happens to any option except -i because it doesn't check for a null and pull the current setting instead.

Create pre-sets for different settings in OpenWebRx.

Last used pre-set will be retained if written to nvram.

It will act as an override to plutoweb.conf during run-time only and will not actually modify the variables or nvram.

Will need a new variable created that can be written to nvram, "openwebrx_override". It will always have an integer 0-4 with 0 being default.

Will need a drop-down menu on the main page and settings screen with 5 options:
0- Pre-set Overrides Off
1- 100ksps - 15 Users Max
2- 300ksps - 7 Users Max
3- 900ksps - 2 Users Max
4- 1.5msps - 1 User Only

The change will take effect when clicking start on the main page or save settings on the settings page.

The $openwebrx_override value will be on line 26 in settings.txt.

This is referring to the config file you see on the 'drive' that shows up when the pluto is plugged in via USB. We should be able to r/w from that file, somehow?

We'll only be building a new image for new releases instead of for every change. An auto-update script can keep older images up to date with the git repo until the next image is out or until its flashed.

• Script should run at boot during S90-S94
• Should be on by default
• Should be able to be disabled w/persistence via settings.sh
• Likely also means adjusting S94pluto-mods to have an earlier start so mods are done and rebooted before the auto-update script fires

Remove...?

Buildroot:
libini
unzip --> #34
compare py sources to py compiled
file

Overlay:
www/putty.zip

Change updatewatch.sh so it processes manually uploaded updates even if auto-updates disabled. This prevents the need to SSH and run updatewatch.sh manually.

Will set it to accept hours only.
