How to configure the COEX interface as input on nRF9160

Greetings,

The only examples I can seem to locate of using the Coexistence Interface on nRF9160 is with the internal GPS but the documentation states that "COEX0: Input to the LTE modem from the external device. When active high, indicates that the external device transceiver is turned on." 

That's the function I'm looking for, where an external device tells the '9160 to be quiet while it's using the airwaves.

I'm not certain I get the  %XCOEX0 AT command, as it seems to relate to using COEX0 as an output that's tied to internal GPS use.  My questions:

  1. Can COEX0 be used as an input from external devices to keep the LTE radio quiet?
  2. Does it need to be configured to behave this way and, if so, how?

Thanks for any hints on this and please don't hesitate if you need more info.

    but please confirm that I did read the docs correctly and that, in theory, this will be possible through COEX0.

     Yes, you read the docs correctly.

    As a PS, it would be really sweet if the docs would mention when a feature is coming soon rather than actually available.

    I completely agree and I'll try to get the documentation improved to reflect the current status of development.
