Intercom Solution

[Ali Khan]

Hi
I am designing an intercom and I need help related to it. The following are the requirements of my project.

I need an intercom module through which two-person can communicate with each other via Bluetooth and also it connects with earbuds for voice communication.
For two persons, I will design two systems. Each system will connect with another person and also with one pair of earbuds.
Any hint or guideline will be helpful.

Let me know if you can help me with it. Thanks

Hi Ali

Do you know which Bluetooth audio profile you are planning to use?

All the Bluetooth audio solutions currently on the market are based on classic Bluetooth (Bluetooth 3.0 or earlier), and Nordic doesn't provide any solutions for classic Bluetooth. 

There is a new Audio profile for Bluetooth 5.2 called LE Audio which we will support, but we haven't yet updated our Bluetooth stacks to implement this, so this is something that will only be available later this year. 

Best regards
Torbjørn
