I starting working with examples for the nRF9160.    Zyphr seems like a very complicated OS (like Linux with device trees, etc) and difficult to use with a debugger.

Is the interface to the modem documented such that I can simply send AT commands from a much simpler application (Say bare metal or with FreeRTOS)?

Yes, the AT commands supported by the nRF9160 modem is documented here. We have a AT client example in the nRF Connect SDK, see here on github.

Best regards

Thanks for the answer.   I was trying to find the documentation on the IPC interface between the application CPU and the modem CPU.  Could you direct me to the right location?  Maybe I am just overlooking it.

Thanks!

The IPC peripheral is documented here.
