Simultaneous LE and BR/EDR

Other Parts Discussed in Thread: CC2564

I've read posts that the TI chips cannot support simultaneous LE and BR/EDR but I was wondering if this is a limitation of the TI chip or if it's a limitation of the BT spec.  The BT spec has a feature for simultaneous LE and BR/EDR to the same remote device in Volume 2, Part C, 3.2 Feature Definitions:

"This feature indicates that the Host supports simultaneous LE and
BR/EDR links to the same remote device.
This bit shall only be set if the Simultaneous LE and BR/EDR to
Same Device Capable (Controller) bit is set on the local Controller.
The local Host sets this feature bit to indicate to a remote device that
the local device is capable of supporting simultaneous LE and BR/
EDR connections to the peer device.
A remote Host uses this feature to determine whether simultaneous
LE and BR/EDR connections are possible to the peer device."

If the BT spec allows this, does anyone know of a chip that supports this feature?

    Hello, I am solving the same problem. Could somebody from TI to explain Jeff's question? Is this feature "simultaneous LE and BR/EDR" available in CC2564 or not? If not, does it mean that CC2564 can't work in BR/EDR and LE mode in the same time?

    Please, could somebody to explain me, too, what exactly means dual mode according cooperation BR/EDR and LE - does it mean that device is able to work with both Bluetooth versions but not in the same time?

    Or is there any possibility to have connected e.g. 3 BR/EDR and 3 LE Bluetooth modules to one BR/EDR/LE module in same time (to create this mix-type of piconet)?

    Same question here. I also found the support in the spec. However, I'm concerned that the Hardware or the Bluetopia stack might not support it. BR/EDR will still be important for our application in 2015.
