Is that BLE Host is a Software or Hardware ?

[prabakaran]

I was going through online material all of which mention that the profiles and protocols (GAP,GATT,L2CAP) i.e. the host for a BLE implementation is a software stack rather than a hardware IP. Is there a reason for this? I am sure that an application specific hardware IP will be more power aware and provide better performance than a MCU based software stack. So, what is the reason for choosing to implement the BLE host as a software stack? Am I missing anything here? Please enlighten and elaborate. Thanks for the help.

I'm a little puzzled by this question since most communications stacks I encounter are implemented as software not hardware. I would say one major reason would be to allow for future upgrades for new features and patches is one reason to implement in software.

Thank you for the valuable comment. I too thinking of that same reason.
