Coexistence interface

On the nRF9160 DK, there are three COEX pins enabling coexistence handling between multiple wireless devices. These pins are routed to the nRF52840 for use when nRF52840 is used as a network processor. These signals are also available on connector P24. In addition, COEX0 is used to enable the Global Positioning System (GPS) Low-Noise Amplifier (LNA) of the nRF9160 DK.

RF control interface

nRF9160 has an interface allowing the modem to control external RF applications, such as antenna tuner devices. There are three MIPI RFFE interface pins, namely, VIO, SCLK, SDATA and three MAGPIO interface pins, namely, MAGPIO0, MAGPIO1, MAGPIO2. The MAGPIOs and MIPI RFFE pins are not in use in this Development Kit (DK). The user can access the signals through test points. See the following table:
