Re: QnetGateway with DV gateway access point mode

 

I finally got my 4100 installed in my radio room. I updated the 4100 firmware to the 12/13/2019 version. I'm running on a raspberry pi 3 using fully upgraded buster (10.2) and it seems very solid in Terminal Mode. Had it linked to XRF735A last night for the entire Trains Net, including the pre-check-in. This morning, I've been connected to REF030C for three hours now with no problems.
New version of qnitap (for Terminal and Access Point mode on a compatible Icom radio)

 

Based on recent postings from several users. Colby W1BSB and I have been working hard to improve the reliability of Terminal and Access Point Mode. I'm not quite sure what happened, but I suspect (without 100% certainty) that recent updates to the Raspbian kernel have subtly changed the USB serial performance and uncovered some shortcomings in my original qnitap code.

I have made some adjustments to the qnitap code and Colby on his ID-5100 and me on my ID-51plus2 are once again experiencing excellent stability. Unfortunately we have a ID-4100 user that is still having some problems and we are continuing to try to troubleshoot this. If you are running QnetGateway on an ID-4100, we could use some more help checking the new code and letting us know how it's working.

If you use Terminal and/or Access Point mode, be sure to upgrade your Icom radio to the latest firmware. All Icom D-Star radios now have available new firmware released on Dec. 13, 2019. Except for a "four-finger startup, it's very easy to install. To install the new firmware, you need the Icom digital cable and a windows computer. The new firmware installer along with detailed instructions can be found at the .

To get the new qnitap software, go to your build directory and do a "git pull". Then you can use the qnadmin script to rebuild and reinstall the software. Alternatively, if you've installed the bash_aliases* you can do:

git pull
make base
make itap
stop itap
start itap

*To install the bash_aliases do "cp bash_aliases? ~/.bash_aliases" from the build directory and then restart your shell. If you already have some customization in your ~/.bash_aliases file, you'll need to add the content of bash_aliases file yourself.

I wonder now if its a firmware bug?? Has anyone bothered to look and see if there are any firmware updates?

Ryan, does the 9700 support AP/Terminal mode? And you have no issues with that setup?

For what its worth, I have had a lot of trouble having QnetGateway work consistently in AP/Terminal mode with the ID-4100.? The exact same configuration of QnetGateway with the IC-9700 is flawless.

The 4100 is definitely doing something different than the 9700.? When I have time, I will try and pin-point the discrepancies.

Re: QnetGateway with DV gateway access point mode

 

I hate to bring up brand-X. But the latest beta of Pi-Star has no trouble with this exact setup. However I would prefer to use QnetGateway if I can.

So here is whats going on.

QnetITAP is the program that controls the itap modem. It expects to receive data from the radio every so often thats automatically generated, you don't have to do anything at all for this to happen. If it doesn't receive anything for 10 seconds, it shuts down itap and attempts to restart it.? That is whats causing the gateway errors that you see with gate2modem not being found. Once the ITAP application exists, the gate2modem socket is closed, and the gateway can't talk to the modem anymore.
Whats troubling is whats causing the radio to stop responding. Are you using a genuine ICOM data cable hooked to the radio and then to the pi, or are you running any USB extension cables, a non icom cable, etc?
Re: QnetGateway with DV gateway access point mode

 

Yeah, I thought this might be a power-saving sleep setting of some kind. I am using the factory ICOM cable with no extensions. Both the radio and cable(s) are brand new. This actually seems to happen right in the middle of activity. You can see between the modem cycles... people are talking.

In the process of my efforts yesterday, I also switched to a different Pi. I think the one I'm on now is a 3B+. I just took a look and the same problem is occurring this morning. From the log, it looks like the modem is just cycling every few seconds... which seems to be causing those gateway errors. Nothing in dmesg that is noteworthy. And I am using a brand new power supply of relatively good quality now.

Thanks for the suggestion. I decided to go brute force and I re-imaged my SD card with Raspbian Buster. Then I set everything up from scratch. It's running now. If I encounter more problems I will do as you suggest. I believe I have a new Pi power supply sitting in my mailbox as I speak.

After all those errors... a few minutes later it just started working again. I didn't touch it.

Re: QnetGateway with DV gateway access point mode

 

I figured I'd go ahead and give this another go. I updated the version of stretch that I had. Uninstalled qnetgateway and rebuilt it from source. No joy. I've attached a screen shot.
Re: QnetGateway with DV gateway access point mode

 
Edited

Yes, I did read about the problem with switching modes. But I had not done any of that. And the connection simply failed... on multiple occasions. I typically monitor the gateway log as it's going by. So I see it immediately. Error messages scrolling by about losing connection between what appears to be the gateway and the modem components of the software.

If you switch the radio out of terminal/access point mode, QnetGatway will drop its connection to it and it will have to be restarted.?

When you say it was just sitting there running, was the radio in terminal or access point mode and was its mode switched between one or the other, or DV/Repeater mode?

Unfortunately, QnetGateway was not able to consistently maintain a connection to the radio. Even when just sitting there running... the connection between the radio and the Pi would flake out from time to time. So that's not going to work.

Wow. Just tried the access point mode and it worked great. Thanks for the tips Colby. I appreciate it.

When you set the 4100 to access point mode, a frequency screen should appear.? Set the frequency to whatever your desired frequency is.

?

The QnetGateway configuration is important here because whatever radio you intend on using to access the 4100 has to be configured according to your call sign that QnetGateway is configured for. For example, if QnetGateway is configured on module B as Terminal/Access Point with a callsign of A1BCD, then you must configure the radio you intend to talk to the access point with those settings in RPT1/RPT2 (A1BCD B, A1BCD G).

?

Its pretty simple really. Two call signs are not required. I believe the legacy ICOM stuff requires it much like ircDDB.net requires a second callsign. QuadNet, and QnetGateway, however, do not.

?

So fire your 4100 up on access point mode, program whatever radio you want to talk to it with the information that matches your qnetgateway configuration, and talk away. Its that simple.

?

Greetings. I just bought an ICOM ID-4100A specifically for it's terminal mode. I'm running QnetGateway and it works pretty well. I am having the same issues as have been reported... where the Pi loses connection with the radio in certain situations. But that's not what I'm posting about.

I'm interested in configuring this for access point mode. However the ICOM supplementary manual on the DV gateway feature specifically says that one needs TWO call signs in order to do this. Any thoughts? Can someone possibly assist me on how to configure this access point mode? I do have the terminal mode working.
