NRF52 and talk application?

[Gót G?y]

Hi! I have to do an application is talk via bluetooth. I think i use codec IC to sample the voice then send data via bluetooth. In the receiver device , I use other codec IC to decode to play the voice. Can I use nrf52840 to do this? and have any example for me? Thanks for any help !!!

Yes you can use nRF52832 or nRF52840 (note that later is not available in production version yet), they both support I2S digital interface for communication with sound-specific ICs (codecs). Note that there is no BLE profile for interoperable sound transport and BLE is not meant for data streaming so you will need to define your own profile or re-use some of examples (like Nordic BLE UART Service with PDU and MTU extensions). But in the end it should achieve throughput needed for voice quality data rates. When it comes to I2S examples there are some in nRF5 SDK but nothing with BLE profile integrated, that is work for you.
