Abstract: A method of digital radio communication between a central device and a peripheral device. The peripheral device transmits a repeated burst of advertising packets on a primary physical channel, each packet comprising an advertising field indicating an availability to form a connection. The advertising field comprises an address identifying the peripheral device. The peripheral device transmits a subsequent advertising packet on an auxiliary channel. The central device receives a packet from the burst of packets, decodes the advertising field and compares the address to one or more desired connection addresses to determine whether to initiate a connection to the peripheral device. If the address matches a desired connection address, the central device initiates a connection to the peripheral device. If the address does not match a desired connection address, the central device resumes listening for further advertising packets.

Abstract: Disclosed is a semiconductor device 2 comprising a radio transmitter hardware section 10 and a processor 4, the device 2 being arranged to transmit information via said transmitter hardware section 10 from a first application running on the processor 4 in accordance with a first communication protocol or from a second application running on the processor 4 or a further processor using a second communication protocol, wherein the first application is configured to generate a first transmit request 24 when it requires to send a data packet and wherein the second application is configured to generate a second transmit request 34 when the second application requires to send a data packet, the device further comprising control logic 22 for allocating a transmission timeslot for said transmitter section 10 to said first or second application upon receipt of said first 24 or second 34 transmit requests respectively.
