half-duplex voice transmission via BLE

[Vladimir]

Are there examples of half-duplex voice transmission via BLE, using nrf52? For example, ST offers the library BLUEVOICELINK1

Hello,

You may find some discussions in this forum searching for BLE and audio. Typically it will be low quality and long latency, so it may only be used for voice audio, there is no native support for audio over BLE using a phone.

That said you may find both Nordic Thingy interesting:

And the nRFready Smart remote 3 interesting for transferring voice commands:
