HID on iOS/Android - Telephony & Consumer usage

[chd]

Hi guys,

I got some questions with HID over GATT on iOS/Android:

1. Does iOS/Android handle Telephony usage input (e.g. for phone pickup/decline)? If not, is there any way to do phone pickup/decline using other HID usage & keys?

2. Specific examples of AL (application launch), AC (application control) keys in Consumer usage? Did anyone actually send these keys to an iOS phone for some specific use case?

3. How to mimic home button on iOS devices?

Thank you for any information!

Hi Chuong,

Sorry for the late response.

• We haven't tested using Telephony command as consumer control on HOGP, but I read on some online forum that it worked, at least on iOS.

• In this link, provided some information on how to launch an app via keyboard: http://www.howtogeek.com/175267/the-htg-guide-to-using-a-bluetooth-keyboard-with-your-android-device/

Perhaps this is what you mentioned for Telephony: e2e.ti.com/.../365376

I tried using the same report descriptor as well as the way to send keys (2 bytes for consumer & 1 byte for telephony) like them. I can confirm that the consumer keys work (e.g. Volume up/down), but for the telephony, the phone doesn't response (e.g. sending hook switch (0x20) upon incoming calls trigger nothing).

Can you help to test on your side?

Thank you
