I use a controller to control lights in a room. It has switch plates as inputs and dimmers/relays as outputs. I wish to use Bluetooth on mobile to control the lights. I expect that I connect a Bluetooth transceiver to room controller via a serial link. My Questions: -
- What will be the mode of operation? Given that only few bytes need to be exchanged, I assume that it should be BLE. Do mobiles have options to select between BLE or BR/EDR mode of operation?
- Given that there may be more mobiles in the room, what kind of operation topology I shall expect i.e. Master-Slave. I believe that Bluetooth device can change roles. The command data, at most of time, will originate from mobile.
- Any idea about the Bluetooth transceiver chip-set that I can use to connect to room controller.
- Does the latest mesh net in Bluetooth comes to rescue? I believe it’s meant for sensors etc.
My knowledge on Bluetooth is limited so please bear with me. Also, I have not thought of how app will be developed, I thought that I shall first establish basic Bluetooth concepts. The Wi-Fi option is not considered since it could well mean creating another Wi-Fi network. Any inputs are welcome. Thanks in advance .
