CC2540 role

Other Parts Discussed in Thread: CC2540

Hi BLE experts,

I am currently using a pair of CC2540s for a project, and I have few questions:

1: There have 4 roles in GAP: Broadcaster, Observer, Peripheral and Central. In case one of my CC2540 configures as Broadcaster and the other CC2540 as Observer/Central, what kinds of information can I get at the Observer/Central side? Can I get the RSSI information?

2. And can I broadcast some message from the Broadcaster?

3: I am playing with the simpleBLE and KeyFob sample, and I want to change the RF's power, how can I do it? Also is there somethings like the "RF Power Table" as for the Bluetooth 2.1?

Thanks in advance,

James
