The Nordic-proprietary %XCOEX0 command writes the COEX0 pin configuration to device's RAM memory.v1.0.xv1.1.xv1.2.xv1.3.xpti_v1.1.x≥1
The COEX0 pin can be configured to switch its state based on the modem's RF frequency, for example, to enable external Low-Noise Amplifier (LNA) in Global Navigation Satellite System (GNSS) mode. The behavior is similar to the %XMAGPIO command with the difference that this command controls only one pin.
The %XCOEX0 command needs to be sent before any modem activity occurs. Based on the given configuration, the modem applies the COEX0 state corresponding to the RF frequency range automatically during runtime.
