Simple UART based CLI for Zephyr apps?

Hello CircuitDojo Community,

Developing firmware for the sparkfun_thing_plus_nrf9160 board, I am at a point where I want to pull in a UART based command line interface. I see that Zephyr-project offers a full featured interactive shell. But this provides quite a few more bells and whistles than I am needing, and I am not sure I’ll have the resources in the end to run this shell in a couple of other targeted microcontrollers where I am planning to port current Zephyr application works of mine.

I’ve spent a few hours searching and researching Zephyr shell, but find no “very basic” Zephyr based CLI projects in the open source world. Is anyone here familiar with such a resource? Any recommendations?

Thank you in advance for any help to spare reinventing the wheel!
