After upgrade to 1.9 new version I get a lot of ### SMALL FRAME: write 1386
It seems that error only come when using more than one channel.

did you upgrade upgrade both telive and osmo-tetra-sq5bpf to the newest versions?

I have done as descried in page 56 in this forum.
sudo apt-get update
sudo apt-get upgrade #do this if you want to upgrade your system, which is a good idea anyway
sudo apt-get install libxml2-dev #the newest version of telive needs this library

cd ~/tetra #or wherever you downloaded the sources
cd osmo-tetra-sq5bpf/src
#if you modified any files (like receiver1) then rename them
git pull
make

cd ~/tetra #or wherever you downloaded the sources
cd telive
#if you modified any files (like rxx) then rename them
git pull
make

that should work. you can try make clean; make instead of just make, but this should work too

check osmo-tetra-sq5bpf/src/lower_mac/tetra_lower_mac.c if around line 164 you have:

unsigned char tmpstr[1380+13];

if it reads unsigned char tmpstr[1380+6]; , then this means that you have not upgraded properly (there was some problem with git pull). maybe you have some error messages, temporary problems with internet access etc?

Yes there is this unsigned char tmpstr[1380+13]; in line 164. But i can se that run make give a lot of errors.
I have then deleted and reinstall all with your script and then it is working perfectly.
Do I have to do an git pull for update or is it now with all the updates ?
It says 1.9 on top of screen. And sound etc. seems to work again.
Thanks again.

no. git clone pulls the newest sources. git pull just updates it to the newest version (which you already have)

could you add -r -s to tetra-rx in receiver1udp (or receiver1, whichever one you're using) and report if you get any SDS which you didn't get previously?

you can also add -e if you want to see some encrypted gibberish

This is exactly what I have missed for a long time -e
Now it gives more information about who is using the encrypted system. And the best part is that
some ISSI seems to show correct even it says it is Encrypted.
I can not tell why this is true but i think it must have something to do with radio models etc.

I Have also try the -r and -s but i do not see more SDS. But i think is becouse it not so often in use.
But one thing i think has change is that i se a lot of ### ALIVE:xxx ### SDS every day.
I dont think I have seen them before.

yes, some ISSIs are unencrypted. this might be interesting if someone wants to play with traffic analysis (btw integration with maltego is somewhere on my todo list).

the downside is that the -e option interferes with mutessi because there are known SSIs even for encrypted calls.

Possible resize window fft sisplay for adapti to notebook?

no, you can't resize it.
btw you can edit the flowgraph yourself. the simplest would be disable the fft window entirely (right click on the block and select disable).

you can also use the headless receivers and control them via xmlrpc from within telive. this won't display anything. please see "Six channel setup example with UDP transport and receiver with no GUI
controlled via XMLRPC" in the documentation

Hi

Sorry for my english.

Thanks @sq5bpf for your great job and share it.

I have modified the receiver1udp adding the command switch -s -r -e and I have in the telive log file the messages type:
#####MsgType:SDS-TRANSFER MSG
DATA:[\xYY\xYY\xYY\xYYx\xYY ......
len:1032 protoid:XX(Teltronic)####

This is correct?

Thanks!!

yes, if this was unencrypted then this is an SDS with the protocol id reserved by teltronic TELTRONIC | Critical Communications Solutions

try t remove the -e and see if you still see it.

btw if there is something interesting on networks near you, then please send me telive.log if you can (preferably off-list, the address is in the telive documentation)

If I remove the -e switch, I don't see these messages.

-e enables parsing of encrypted messages. since the sds is encrypted, the decoder should give random data

for normal use use only -r -s

Good evening to all friends
After the last update began to show new messages liked to share with you and I hope their interpretation
MESSAG WINDOWS
20161106 16:57:14 FUNC:DRELASDEC SSI:6999999 CID:12611 NID:59 [NOTICE OF IMMINENT CALL DISCONNECTION] RX:5
20161106 16:58:23 FUNC:DRELEASEDEC SSI:5999999 CID:13747 NID:60 [RESERVED] RX:5
Strange thing is that I write them to a text file by WORD, show me automatically CID: 12611 blue signify that link to the page or it Hyperlink

It is what I try to change, but I can not find true value of 256 for the handset display that cuts under the last menu
Also in the "notebook" empty box I do not understand what to put
For hi documentation is always on your desktop and reread it each time I find it difficult
Another tip on the values ​​to be included?
Thank you

Hello guys, just want to ask if anybody uses telive in Kali linux platform, because when I wanted to start fresh telive install in Kali (./install_telive.sh) it gives me "bug" that it can't install gnuradio and etc. So maybe someone had the same problem and managed to fix it? Thanks!

you didn't give the exact error message so i can't be sure whats going on, but try to install gnuradio 3.7.5 or later yourself, and then run the install script again
