Is it possible to detect BLE devices such as a pebble watch?

[Charles Dasher]

I have a BLE wearable (Pebble watch) that I wish to detect using the nrf51822 evaluation kit. I can use the Control Panel to see the pebble. I would like to be able to us the nrf51822 eval kit to detect when the pebble is near so that I can trigger an arduino to turn on lights, etc when the watch is nearby. Is this possible (I don't mind using the Master Control Panel to get the initial information about the Pebble to use in order to detect it with the eval board).

It should be possible.

I recommend you to look into SoftDevice S120, it can act as a observer and a central. You should be able to scan the advertising packets from the Pebble. Then you just need to trigger on some identifier in the packet, for example the name, the UUID, or the address. You should be able to get this information form MCP.
