BLE specifications allows following combo/multiple roles:
- Peripheral + Observer
- Peripheral + Broadcaster
- Central + Observer
- Central + Broadcaster
If noted carefully above allows only a star network with only one central device in a network:
[Peripheral + Central] combo role is required to extend the range - Example: Central ---> [Peripheral + Central] ---> Peripheral. Now Central is two BLE lengths away from Peripheral extending the BLE network to double. This is what CSR Mesh may be doing.
Question: Is there any way to extend the TI BLE network in such a way (may be like or another way):
Central -> [BLE Combo or other implementation] -> Peripheral.
