BLE topology

Hi, I'm developing a wearable fitness device. The device collects accelerometer-gyro data and sends it to the mobile application. Initial developments are good, I created my own services and can successfully communicate. Now I want to collect live data stream from two such devices parallelly. The idea is to capture both hand gestures using two wireless devices. I tried BLE mesh, but the mesh does not support a high data rate. I'm confused, I don't know which protocol to use. I'm new to BLE, please help me to figure it out.

  • 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.

  • I need both devices to communicate each other.

    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?
