Before running any of the proprietary RX or TX radio operation commands, the radio must be set up in proprietary mode using the command CMD_PROP_RADIO_SETUP or CMD_PROP_RADIO_DIV_SETUP, or in another compatible mode with CMD_RADIO_SETUP. Otherwise, the operation ends with an error. The RX and TX commands also need the synthesizer to be programmed using the CMD_FS command, which can typically be done by a command chain where an RX or TX command follows immediately after the CMD_FS.
