Commands in this section need to be given only after device power-up or in device production. If the AT+CFUN=0 AT command is given in the production phase, it stores the given AT command’s content to nRF9160's non-volatile flash memory.
An MIPI RF Front-End Control Interface (RFFE) device can be configured for nRF9160 with the Nordic-proprietary %XMIPIRFFEDEV and %XMIPIRFFECTRL AT commands.
