BLE Multi hop or daisy chain communication

Other Parts Discussed in Thread: CC2640R2F

We have a BLE application where we need hopping through nodes. I have shown below how it looks like. We don't want mesh network because we don't require node to node communication. So, in diagram, gateway wants to communicate with module4 but it can't reach. So, route is through module1 through module3. Are there any sample projects for doing multi hop on BLE ?

    Hello Pavan,

    BLE does not define any routing based profiles as of now (Bluetooth 5). So, you would have to implement this logic in your application. One way is to use the ADV channels and listen/re-broadcast (similar to mesh) or use a CC2640R2F multi-role enabled application on your ModuleX nodes to connect with the peer devices (one master one slave). You will need to define the data transfer via GATT based on your implementation requirements.

    Best wishes
