How to launch Siri from nrf51?

The HID usage is usage page 0x0C (Consumer Controls), Usage 0xCF (Voice Command), but it requires an Apple Authentication Coprocessor v2.0c to be incorporated into the device issuing the command to launch Siri.

Ok, I got the device and the results are... inconclusive.

This device does not use Bluetooth LE, it is most certainly a classic Bluetooth device. The chipset inside is this: www.broadcom.com/.../bcm20730

Now, I am still not convinced that the nrf51 won't work. This is a HID device, so it should be possible to mimic this with HID over GATT. When my iPhone first detected this button, for the briefest of moments it showed up as a generic keyboard.

I will keep trying different HID keys, that must be the answer...

Well, the device arrives today and so we can hopefully figure out the answer! My money says it is some undocumented HID key that can trigger it, many keyboards seem to be able to do the same. I did try some of the keys labeled Home, but couldn't get them to work, so not sure what it is exactly.

Well there is one - the HFP extension is documented for this - however HFP isn't available over BLE as far as I know, only BR/EDR. Since the device looks like it's BLE, the only other option I could come up with is that it's both, it does most work over BLE and uses BR/EDR for HFP or other services which require it.

Unless there's a BLE-available service on iOS which enables Siri, and I've never found one, a dual mode chipset is all I could come up with for being low energy and also able to support HFP

The point remains that this will not be specific to the Bluetooth chipset in the device - it will have to be relying on some standard service/API/facility in iOS

The only other thought I had last night was the chipset was dual mode (I've almost forgotten about good old BR/EDR Bluetooth) and thus supports both. If you're able to sniff the LE connection all the way through pairing and keep it going, you'll at least be able to see what the BTLE bit does when you hit the siri button.

@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

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...?

@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

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...?

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
