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.
