Original question:

CC2564: Operating Classic (Assisted A2DP Sink) and BLE (SPPLE) simultaneously

CC2564: Dynamically switch between BLE and assisted A2DP/HFP

Part Number: CC2564

Hi. The datasheet for the CC256x states in 1.4:

"The following technologies and assisted modes cannot be used simultaneously with the coprocessor: Bluetooth low energy, assisted HFP 1.6 (WBS), and assisted A2DP. Only one technology or assisted mode can be used at a time."

Is it possible to switch between BLE and assisted A2DP / HFP at run-time (without a power cycle and loading the appropriate script)? E.g. use BLE to scan for devices and then connect via BR/EDR and enable assisted A2D? PIf yes, how?

Thanks,

    Yes, it is possible to switch the feature on the co-processor dynamically. But, this means to download the feature patch from the MCU when ever the co-processor functionality is switched .. 

    Thanks

    Thanks for the reply. Following up: how to switch e.g. from BLE to AVRP? Do we need to  power-cycle the CC256x, or can this be done while its running, and we could e.g. keep a BR/EDR ACL connection alive?

    Is it enough to just send the HCI Commands in the AVRP add-on and activate AVRP, and later, send the two HCI Commands of the BLE Add On? (I always thought you'd need to power-cycle to re-load the BTS scripts).

    Best
