An electronic device is provided. The device comprises a radio transceiver, a processor, a memory, a connector, and an application stored in the memory. The connector is for coupling a radio frequency signal between the radio transceiver and an external antenna and for coupling a baseband signal between the first processor and an external processor. The application, when executed by the processor, manages the radio transceiver based on baseband messages received over the connector from the external processor, wherein the application managing the radio transceiver comprises causing the radio transceiver to transmit the radio frequency signal over the connector to the external antenna and causing the radio transceiver to receive the radio frequency signal over the connector from the external antenna.
