I can't change the format, but shell_set_bypass() looks like it does exactly what I want, thanks.

Hi,

Zephyr doesn't allow or support commands with symbols like " : ". It only accepts normal letters/numbers. I can suggest a few solutions.

1) You might want to try to change from :Cxxxx to cmd Cxxxx or c Cxxxx.

2) Try using "bypass mode" which basically tells Zephyr to temporarily stop interpreting commands and send all UART characters to your own parser. You get to keep your format of :Cxxxx. Zephyr provides shell_set_bypass() for this. By using standard shell command like legacy on / legacy off, you can enter/exit this mode.
