Pre-calculation of sub-event RF channel

A system for pre-calculating an RF channel in a short-range, wireless communications low-energy protocol in a connected isochronous stream (CIS) between a master wireless communications device and a slave wireless communication device, the system comprising:

• one or more processors coupled to non-transitory memory storing machine executable program instructions that when executed by the one or more processors, cause the master wireless communications device and the slave wireless communications devices to:
• calculate an RF channel between the master wireless communications device and the slave wireless communications device for a first sub-event among a plurality of events, the first sub-event occurring at a first time in the CIS;
• and
• pre-calculate an RF channel for a subsequent sub-event among the plurality of events while calculating the RF channel for the first sub-event, the subsequent sub-event occurring at a second time in the CIS, where the second time is subsequent to the first time.

A computer program product for pre-calculating an RF channel in a short-range, wireless communications low-energy protocol in a connected isochronous stream (CIS) between a master wireless communications device and a slave wireless communication device, the computer program product comprising:

• a non-transitory memory medium, the memory medium containing machine executable program instructions executable by one or more processors, the program instructions including:
• program code, which when executed by the more or processors, causes the one or more processors to calculate an RF channel between the master wireless communications device and the slave wireless communications device for a first sub-event among a plurality of events, the first sub-event occurring at a first time in the CIS;
• and
• program code, which when executed by the more or processors, causes the one or more processors to pre-calculate an RF channel for a subsequent sub-event among the plurality of events while calculating the RF channel for the first sub-event, the subsequent sub-event occurring at a second time in the CIS, where the second time is subsequent to the first time.
