1. A wireless BLUETOOTH transceiver device, comprising:

  • transmission circuitry to transmit synchronous and non-synchronous data;

    receiver circuitry to receive synchronous and non-synchronous data; and

    baseband processing circuitry operably coupled to the transmission circuitry and the receiver circuitry, the baseband processing circuitry including;

    memory for storing synchronous and non-synchronous data; and

    circuitry defining logic determining whether transmission of a packet of the non-synchronous data may be initiated without colliding with a packet of the synchronous data scheduled to be transmitted over a plurality of time slots, and when the transmission of the non-synchronous data packets may be initiated without colliding with the packet of synchronous data, initiating transmission of the non-synchronous data packet; and

    the circuitry further defines logic that evaluates a time value with respect to a bit stream modulo to determine what bit in the bit stream corresponds to the present time and which time slot of the plurality of time slots a synchronized event is scheduled to be transmitted.
