Customers should be aware that if 5-slot A2DP packets are in use with a CSB Interval of less than 20 slots, this may negatively impact A2DP reception

The success rate of Page and Page Scan activities is significantly reduced when Broadcast Audio and A2DP audio are simultaneously active, due to the inherent time-division nature of Bluetooth. These effects can be mitigated by increasing the duration for which Paging or Page Scanning is performed. There may be some reduction in the success rate of Page Scan and Inquiry Scan for values of CSB interval like 8, 16 or 32 which are divisors of 2048 or 4096.  Connectionless Slave Broadcast
