Why?

BLE peripherals can't communicate peer-to-peer.

So they'll either have to communicate via the Central, or one will have to be a Central to the other.

Or use a different protocol between them.

I still don't see why this requires the 2 devices to talk to each other?

Exactly. Also I need both devices to communicate each other. I want both devices advertised as one device. And button event in one device should affect both devices. For example, consider a wireless earbuds. They advertise as one device, button control in one device influence both earbuds. In my case instead of streaming to two earbuds, i want to collect stream of data from two devices. Thank you.

So just have your Central (the mobile app) connect to the 2 peripherals at the same time?
