https://devzone.nordicsemi.com/f/nordic-q-a/25002/android-tv-voice-input-with-smart-remote-3Android TV devices such as Nvidia Shield, Xiaomi MiBox and Nexus Player have support for voice input via their BLE remotes. I&#39;ve researched it a bit to figure out how it works and this is what I&#39;ve gathered: In the android world, command processingen-USTelligent Community 13Fri, 08 Sep 2017 14:23:58 GMThttps://devzone.nordicsemi.com/thread/98469?ContentTypeID=1Fri, 08 Sep 2017 14:23:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fe0853ae-306b-432b-bb43-dc2f3a3e84f3Sigurd<p>Hi,</p> <p>Yes, the <a href="https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRFready-Smart-Remote-3-for-nRF52-Series">Smart Remote 3</a> streams voice using HID over GATT, and supports several codecs, including ADPCM and Opus.</p> <p>Since voice-over-BLE is not a standardized profile, the requirement for this to work is that the same profile and configuration is implemented on both the remote and the TV.<br /> For now, every manufacturer uses his own method/configuration to stream data, so a AndroidTV remote for one device, won’t work with all the Android TVs, but this will most likely improve in the future.<br /> So in order to get the Smart Remote 3 to work with a given AndroidTV, you need to configure the Smart Remote 3 exactly with the same configuration as the AndroidTV uses(same codec, sampling frequency, frame rate, etc).</p><div style="clear:both;"></div>
