ax.25 error shown in direwolf. Fails on channel 8, then 2, then works

Question

Using a Raspberry Pi 3B, Signalink, HT, direwolf and ax25-tools and ax15-apps. All up to date. Clean start.

Commands:

sudo direwolf -p  
sudo kissattach /tmp/kisstnc wl2k

obtain assignment to ax0, then

beacon -s wl2k "testing"

first attempt - direwolf reports: Invalid transmit channel 8 from KISS client app.
second attempt - direwolf report: Invalid transmit channel 2 from KISS client app.
third attempt - works just fine and the RPi transmits the "testing" perfectly.

I want to address the channel issue and can find nothing in documentation. What is going wrong, what can I do to fix this?

This is issue #42 on Direwolf's GitHub page.

To work around it, put the interface into CRC mode "none" with a command like this:

# kissparms -c 1 -p radio

$\begingroup$ Thank you Mike. Actually figured this out by examining dmesg dumps. Came up with the exact same command line. Glad I was on the correct track. $\endgroup$ – ASzy Jan 30 at 0:02
