voice transmission using nrf52

[Ankush]

Hi I am working on nrf52 kit. Can I transmit Voice using nrf52 to any other device? Can anyone Please suggest any algorithm.

You can transmit whatever you want, as long as you fit in the throughput... what "voice" do you want to send? is it needed to be transmitted in real time?

i want to transmit the speech signal to another nrf52 kit.not necessarily in real time .As I am a beginner, Can you suggest some flow for this or any sample example.

Why don't just treat voice as normal data? You can transmit it using ex. NUS service (via BLE) or by ESB if higher throughput is needed. You need to do calculations how that voice is sampled (frequency and resolution) and then fit it somehow... you want to connect microphone to nrf52 or what?

Yes, you can transmit voice using nrf52. I sent audio (more music, but voice is the same) between two nrf51, so the nrf52 should work too. And if you only need one way you can achieve good quality. I used NUS, but you can choose other profiles and just change the data to your audio data!

Thanks for your response.Yes I can use voice as normal data.I want to use microphone to read the voice but I don't know how to use microphone with nrf52. Do you have any solution to this?
