BLE and ANT coexistence on one part

Other Parts Discussed in Thread: CC2540, CC2570

Hello. This has probably been asked many times before, but I am trying to find a way for ANT and BLE to coexist on one part. They do not have to be active at the same time.

* Can we place the ANT stack in CC2540 memory, and call that stack as needed? My understanding is that the hardware is the same for both, so it really would depend on the ability of the CC2540 to accomodate the ANT protocol. Will the hardware of the IC allow this?

* Any other viable solutions for BLE & ANT using a single IC?

A seperate question, the CC2570 is listed as a NETWORK processor, as opposed the the SoC CC2540. Does the CC2570 have the ANT stack on board? How exactly is the term NETOWORK PROCESSOR defined?

 

Thanks for your help,

Chad

    Hello,

    You can look at 2567 which has both ANT and BT, and I believe that group will add BLE stack support,  but you may want to ask in that forum.

    As far as 2540, this is not possible currently. This is due to licensing of ANT stack which is ROMed into CC2570.  The 2540 and 257x chips are pretty much identical, so technically it would be possible.

    Both CC2540 and CC257X can be network processors, which means an external  MCU is used to drive the chip (with stack) with API commands.  The 2540 can also be run as SOC - which means it does not need an external MCU to drive it, but rather an application compiled will run it and access the stack libraries on chip.

    BR,
