Abstract: An audio receiver for a converged portable radio (LMR/LTE radio) is provided with improved audio management. The converged device is managed by two different processors (BP/AP) and includes a selectable user setting for selecting either an LMR audio mode or an LTE audio mode (or both). Power up timing differences between the two processors is managed through a smart audio switch mechanism which includes AP control logic for selectively enabling and disabling an AP audio switch in response to operational status of both (AP/BP) processors during power up. The smart audio switch system further includes BP control logic for selectively enabling and disabling a BP audio switch in response to the operational status of the processors. Audio is played out at a single speaker. Both LTE audio and LMR audio can be mixed for a predetermined time during power up until the user selected audio mode has been established.

Abstract: A coil-in-coil structure (100) is formed within two devices (106, 108). The coil-in-coil structure (100) enables both wireless charging and secure pairing between the two devices (106, 108). The coil-in-coil structure (100) permits expanded wireless functionality using a single transmit coil (104) at a host radio device (108) and a receive coil (102) at an accessory device (106). A plurality of different accessory devices (606) can be interchangeably accommodated via a single host port (114) of the radio device (108).
