Can ATVV enable SR3's Audio module instead of SR3 enables it?

[Ralph]

Hi, we recently using audio with ATVV service instead of HID service. As we notice, Audio would enable by SR3 itself in ATVV service if we push the key, but not in HID service that SR3 has to wait master device to send command to enable audio.

That cause a little problem if trying to use Youtube voice searching, because we have to push down a key to activate audio, the Google assistance will be called and cover Youtube voice searching. 

Can we change the way of enabling audio from active to passive just like in HID service but still in ATVV service? Does ATVV support audio enabling?

Thanks.

Hi,

I'm not sure if I understand the problem. Is it related to this: https://devzone.nordicsemi.com/f/nordic-q-a/35274/sr3-s-ble-loses-control-after-google-voice-search-on-android-o-device/ ?

Hi, Martin 

No ,the issue of the link is solved. 

May I ask at which part of the post you are confused?

Hi,

What behavior do you want? It sounds like you don't want Google Assistant to pop up, but you rather want the SR3 to function as a speech-to-text device for a text box?

In the best case scenario you can just disable HID if the SR3 detects that the ATVV service is available. But then you are depending on that Google Assistant actually gives you an equivalent speech-to-text functionality.

Hi,

Sorry. 

I was wrong, in original SDK, Push Android TV voice command key couldn't make Google assistant pop out but only enable Audio. 

In SDK, google assistant only be referenced by GOOGLE_VOICE_SHORTCUT_KEY, but it never works so I replace this shortcut key to a new key to send HID command (0x0c,0x221)directly,which can activate Google assistant and also be Android TV voice command key. 

Conclusion:

1. Why GOOGLE_VOICE_SHORTCUT_KEY doesn't work?   

HID_USAGE(0x07, 0xE0)
HID_USAGE(0x07, 0xE1)
HID_USAGE(0x07, 0x37)

2. Now I try original SDK and have to click Google search/Youtube search button on the screen and suddenly push Android TV voice command key,if you are not quick enough to push voice command key, the speech-to-text function will be unresponsive.

Hi,

Q1) The Android TV Voice Service doesn't look for this key code. For some reason Google chose to use another key code for this purpose (0x0c - 0x221).

Q2) I'm not sure what could cause this. What version of the SR3 firmware are you using? We have made some ATVV related improvements in v1.2.1.alpha.
