Permitting coexistence of data transfer of interferring wireless signals

A system comprising:

• a circuitry for a second data transmission protocol,
• wherein the circuitry for the second data transmission protocol is configured to use clear to send (CTS) data packets that protect signals of a first data transmission protocol for synchronous connection-oriented (SCO) communication links,
• wherein the circuitry for the second data transmission protocol is configured to determine when a data transfer of the first data transmission protocol is implemented, and wherein the data transfer for the first data transmission protocol is to occur for a period;
• and
• a data processing system including a processor and configured to cause the processor to:
• calculate the period, wherein a medium contention of the second data transmission protocol is to begin upon an end of the period,
• determine that the circuitry of the second data transmission protocol has entered into a power save mode,
• indicate, from the circuitry for the second data transmission protocol, to a router that a transceiver is entering into the power save mode, and
• begin, by the circuitry for the second data transmission protocol, asynchronous connection-less (ACL) data packet transmissions in periodic data transfer gaps of the second data transmission protocol during the power save mode,
• wherein a data transfer of the second data transmission protocol has no timing constraints, and the data transfer of the first data transmission protocol has timing constraints and occurs during the period.
