I was able to get my sixfab-connected Pi to transmit to my listening-Argon Pi, but I am only able to send one, six-character message. As soon as the sixth character is typed, the message sends automatically. It then appears to error out, and despite letting me type, will not transmit anything else. The minicom AT terminal appears completely unresponsive except for echoing my keystrokes on the screen To get it to transmit again, I have to shut it down and restart the minicom program.
Any ideas why it’s doing this, or what I could try?
