Issues with Voice Over HID over GATT in iOS

[NavR]

We are using nRF52840-DK and we need to stream the audio to our iOS app that we are developing. But currently, we are not able to get the audio streams back for mic to iOS. We have tried every command that we need to send from iOS to NRF52840-DK. Can you please explain the exact process on how to achieve this. Please check the image that I have attached to understand what we are trying to do.

I'm sorry, but we don't have a working solution for doing Voice over HID I'm afraid. It sounds like you are interested in audio over BLE though, so you should check out the (currently in development) Bluetooth LE Audio spec. This blog post on Bluetooth LE Audio was posted just before the holidays in 2020 should be of interest.

Additional information which might be interesting: Last year, we (in partnership with Packetcraft) launched an LE Audio Evaluation platform, using the nRF52832 for radio communication, alongside the CS47L35 smart codec to provide an evaluation platform for LE Audio. More details here.

Unfortunately I don't have any information on when support for this will be released. For details on this, please contact our sales department, as we strive to focus on what's currently available here in tech support.

Best regards,

Simon

Hi Simon, 

Thanks for the reply. Can you please check following video. It's using nRF52840 to transmit voice from the device to Linux. Ain't this being done over Bluetooth LE Voice:
