Re: DSTAR2 and DSTAR1

 

Colby... last night I was playing with some of the other smart groups listed on the quadnet web site. When I tried ILLINK... I received the "not in cache" message. While I did try several more times... each time I continued to get that same message and was never able to actually log in. Is ILLINK misconfigured?

Nothing is in the cache when a hotspot or repeater first boots up. After the first not in cache, it should add the required information to the local cache on how to route to that group, so the 2nd call will go through successfully.

Re: QnetGateway + ID-4100A in Access Point Mode + ID51A Plus

 

That's really interesting. The ackTimer is used to detect when the Icom firmware is locked up and needs to be reset.
The ackTimer is only about moving packets from the internet to the radio. If you are in Terminal Mode, the AMBE data will be decoded and sent to the radio's speaker. In Access Point Mode, the voice stream will be sent directly to the GMSK modulator of the radio's transmitter.
Whenever a packet is received and sent to the radio, the ackTimer is started. THe radio is suppose to send an acknowledgement, one acknowledgement for a header packet and a different acknowledgement for a voice packet. Until qnitap receives the acknowledgement, it will stack up arriving packets in a queue. Once the acknowledgement is received, the next in the queue is sent to the radio.
The ackTimer "threshold" is the time in seconds when itap decides that the radio is foobar and needs to be reset. Resetting is a process where the serial port is closed, the running parameters are reset so that the initialization sequence will be read to go, the serial port is reopened and then the very last thing is to empty the queue and return to the normal processing loop, which will start by initializing the serial communication to the radio.
What I find fascinating is that AP need a bigger threshold than TM.
Did you try something in-between? The serial port reset takes less than 0.1 seconds, so moving the threshold from 60 milliseconds to 1.06 seconds is a very big change. This threshold is big enough to easily hear if the radio locks up during a voice stream, so trying something a litter smaller could make things better.

I was suspecting that card myself.. Colby is sending me info on a better card and I'll switch to it Wed or Thu (next shoppign trip) Oh the fun. First time for either of us using Team Viewer on a chromebook and it did not work as designed.. So he talked. i typed and success was ours.

Make sure there is only one file listed with a: ls -l /lib/systemd/system/qnitap*

Re: QnetGateway + ID-4100A in Access Point Mode + ID51A Plus

 

Hi Everyone;
After some troubleshooting I got it working, I had to change some code in QnetITAP.cpp;?? line 364.? (although that may not be accurate as I was doing some other edits in the file during my troubleshooting so plus or mines a few lines)

The code I changed is below (screenshot)... essentially just changed the tolerance of the ack timer.

Question:? not really knowing the code that well (at all), what are the implications of changing this threshold?

Thanks.

John, you need to take a look at the qnitap log file. The maintenance menu may not be the way to go this time because when it starts, it only shows the last few lines. Try:
sudo journalctl -u qnitap
Then do a "G" to get to the end of the logfile (it may be long if QnetGateway has been running long, so it may take a sec or 2 to get to the end). Then you can back up with your arrow keys and see what's before the message from systemd about being shutdown. Look for the last few messages from qnitap.
It might help to shutdown the pi and the radio, unplug the digital cable, plug it back in, power up the radio and then the pi and see if that helps.

Ok the error is in lime 10 of the index.php Assumign that i teh SQUlte3 database (since it also mentions that) which AL mentioned I tried renaming (not deleting) tje fie (Easier to restore it by renaming it back_) no joy? Suggestions please

I assume 515 is the version number of QnetGateway... If so I should be running it bui how do I figure that out???

Well after playing with it for a whle.. SUCCESS Other than restoring index.php to the original file name. I know not what I did that fixed it.?

?

Check that I still have the error messages but now I have last heard.. OK,? ?Error is now on line 180 of the index.php site.


Re: Important new release

 

Sorry John.

Robert also found an error with qnconfig. Both are fixed. Since these are not C++ files, you just need to do a "git pull" to patch you system, but only if you are running 515.

If "git pull" pulls down any *.cpp or *.h file, you need to uninstall and reinstall.

Thanks to some persistent reminders from DS5HVM and corroboration from W1BSB, I have finally realized that there were problems with the way qngateway and qnlink were opening the sqlite3 database. When I was first developing the sqlite3 database support for QnetGateway, I was seeing some problems with my hot-spot, but I was solving the encountered problems the wrong way. This new release has backed out those solutions and database access is now properly coded, and the code is smaller, so I like that!

Please update your system at your earliest convenience. In the qnadmin main menu, uninstall your system (us), do a git pull (gp) and then install your system (is).
