ModeSDeco2 and ModeSMixer2 - console programs for RTLSDR and transcoding

[Anmer]

Welcome Paul.

What are you running on the RPi that you expect to process the SBS-1 data?  I assume it's an SBS-1 without Ethernet?

[bumpy_up_here]

Hi Anmer,

Your posts have been very helpful over the years, I have referenced many of them over the last few days - thank you.

I am running modesmixer2 and yes you are correct, it is an SBS-1 without ethernet.

One theory I had was that the SBS-1 wasn't getting enough power from the USB socket, so I dug out my original 5v power supply that it came with. Unfortunately it made no difference.

I have tried every combination of port/output I can think of, without success, hence why I've reached out for some help.

The command I am running is:-

./modesmixer2 --inSerial /dev/ttyUSB1:921600:none --outServer sbs10001:10001 --log-level 5 (I have also tried running this with sudo, plus I have done the sudo usermod command from Sergsero's post, mentioned earlier, rebooted etc. Have also tried USB0, have tried both USB0 and USB1 as 2 x inSerial inputs)

The PC based Basestation.exe is definitely talking OK to the RPi feed, as I see messages appear when I try to connect (different messages for different ports).

My gut feeling at the moment, which I have yet to explore further is either a) it won't work whatever I do due, to a change in either OS or modesmixer since 2016 (as per MrMac's entry) or whether I need to do anything with FTDI drivers on the RPi before it will work - I do note that there is no green light on the SBS-1 when connecting. I explored both dump1090 and modesdeco, but please correct if I'm wrong, they are for dongle based feeds only?

I do get an unusual message about SBS-3 LOGIN when connected, which seems to fail after a few seconds - I can provide the exact details if that would help?

MTIA.
Paul.

Edit - had a thought and referred back to Sergsero post on Page 33 - he specifically mentions a Pi 2 - I am using a Pi 3B+ so I wonder if anyone (maybe MrMac?) had this working on a Pi 3B+. I have a friend who can lend me an older Pi so will ask if I can borrow his for a test. Cheers.

Edit2 - borrowed an original Pi B, set it up with Stretch and downloaded the Pi1 version of modesmixer2 - get exactly the same symptoms as my Pi 3B+.
I don't suppose anyone has any older Pi1/Pi3 versions of modesmixer2 maybe from around 2015/16 they could let me try, please? Have tried searching for older versions without success. For me, the big clue is the lack of a green light on the SBS-1 when plugged into the Pi - all functions well when plugged into PC (including green light).

sergsero, any chance to have an x86_64 version of modesmixer2 for Debian Stretch that removes the following error?

./modesmixer2: error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory

I am having to use a 2015 version as a workaround for this. Various "ln -s" suggested fixes for similar problems have not worked

Hello IanH,

...error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory...

I checked the current version of the libssl library in Debian 9 Stretch. At the moment it uses version 1.1.0 j-1~deb9u1:

sergsero@debian9:~$ lsb_release -a
Distributor ID: Debian
Description:    Debian GNU/Linux 9.9 (stretch)
Release:        9.9
Codename:       stretch
...
sergsero@debian9:~$ apt list libssl-dev
Listing... Done
libssl-dev/stable,stable,now 1.1.0j-1~deb9u1 amd64 [installed]


If you are maintaining a current versions of packages periodically executing command: 'sudo apt-get update && sudo apt-get upgrade' to install available updates for all packages installed on the system it would, most likely, that you already have this version installed.

Here is the modesmixer2 that was built with this version of the library:

The following is the output of ldd command for the modesmixer2 v.20190413 ('ldd' is a command line utility that is used to print the shared objects (shared libraries) required by each program):

Thank you 

My outpu of "lsb_release -a" and "apt list libssl-dev" were identical to what you posted.

The modesmixer2 v.20190413 version is now working on my system 


Thanks also to graeme61 who offered a fix for the problem - with the recent version of modesmixer2 I do not need to try that.

With the problem with Google maps stuck into developers mode will there be a way or a update that will allow the use of other maping services or programs like open street or Bing map layers?

Hi!

Where can I get the latest version of modesdeco2?

Cheers,

Hi everyone,

I've been using ModeSMixer for quite a while now. Very happy. Great product!

Just one thing bothers me - if I have to power down my pi for whatever reason, I lose all that lovely data I've built up.

Is there any way of backing this data up at all? Where is it stored. Couldn't find it in /var/www for example.
Thanks!

[Anmer]

Welcome.

Are you using Virtual Radar Server?

[doctorvenables]

Hi,
No I have piaware on my pizero, which feeds both the adsb and mlat data to modesmixer on a second pi. Not using VRS at all (used to - switched to modesmixer about a year ago.)

[Anmer]

Thanks.

I saw VRS in your signature and was going to ask if you have a BaseStation.sqb running with it.

I'm guessing there's no database with your setup?  But others, with ModeSMixer experience, may know better?

[abcd567]

I am using latest version of modesmixer2 (modesmixer2_rpi2-3_deb9_20190223.tgz) on RPi. It retains all MAP data (maximum range plot) even after reboot.

I installed it using following bash script:

Code Select Expand


sudo bash -c "$(wget -O - https://raw.githubusercontent.com/abcd567a/mm2/master/install-mm2.sh)" 


This method works on following images:

• Piaware SD card image, with integral dump1090-fa.



• Raspbian Stretch/Buster images with package install of piaware + dump1090-fa/dump1090-mutab.
  

Please see my above post for details.

[doctorvenables]

Ahh I see my signature was well out of date. Have fixed.

Thanks Anmer - I do have BaseStation.sqb and flightroutes.sqb running at that's fab.
abcd567 - that's a new one on me to install like that. Previously I'd just been downloading the .tgz file unzipping into a folder and using a sh script involving the screen command. I'd been playing with trying to write a service yet it looks like that's all been taken care of! Will try reinstalling with your method - Im sure it'll work.
