Alright, I have searched high and low and been unable to find a simple answer to this question. It must be possible for the nrf51 to launch Siri on an iPhone, I have seen product using it mention this as a feature. But I cannot find out the way to do it.
Anyone know how? Is it a special HID media key? Or some other profile? All I want to do is launch Siri, not interact with it, so the equivalent of holding the iPhone home button.
What product? Is it low energy? The only way I've seen you can do this is with an extension to the hands free protocol which I don't think is available on BLE
Perhaps the "product" in question has an app which receives commands over BT (whether low-energy or otherwise) and it is the app which actually launches Siri - not the BT device itself...?
@RK: Yes, that is sort of what I was able to find out as well. The only documentation I can find from Apple seems to indicate you need HFP, but I think that you are right in that it isn't supported in BLE. Here is one product that advertises the feature, I am pretty sure it must be BLE (though I cannot 100% confirm), but based on the battery life I would think it is the only way: www.amazon.com/.../ref=sr_1_1
@awneil: I am open to this approach as well, the problem is I also cannot find a way to launch Siri through an app ;-) Apple doesn't seem to have an API to do this in their SDK and Siri access is relatively locked down
That product description says there is no app - so it must be something native to iOS. Have you tried asking on iOS-specific forums?
Maybe buy one, and see what services it is advertising...?
@awneil: I purchased one, will get it tomorrow and see what it advertises and what chipset is inside. I will keep trying and post here if I find the answer
