Voice Transceiver Over BLE

[Murugan]

Dear Nordic Team,

Thanks for support.

I want to know the possible for voice file transfer to over BLE. I am using BR281 audio detection on semiconductor. I want do the below process.

1. Voice record and save
2. Voice transfer

Hi,

As Stian said, this is doable. You will have to evaluate different audio codecs vs. the datarate and processing power you have available, if you want to store audio you might also need to use an external storage (audio can take a lot of memory).

Often it will make sense to process or compress the data before sending it, if the current consumption from CPU activity will be lower than the current consumption for radio activity for sending uncompressed data you will have less current consumption, and possibly also less delay.

Best regards,

Øyvind

Thanks for the reply. Have any predefined service for audio file transfer or make a custom service ????

Hi,

There might be some service already made for hearing aids, otherwise look towards a custom service.
