The BCM20706 Development Board and associated SDK will need to go into production, which should occur sometime near the end of Q3.
Note that there will actually be a special slimmed down version of the SmartReady SDK that will support HomeKit, and to gain access to it (around the same time), you will need to provide your MFi number to GregG_16 or jota_1939431 and one of those two will be able to provide you access to the internal space where you can download the SDK.
Thanks kwang for your prompt response!
Is there any board that I can start working with? and later just migrate everything to BCM20706? Or you think that it might be a waste of time?
We don't have any pre-development boards at this time.
We will keep you informed on the release date.
