How to get rssi without connection via central device

[purgoufr]

I use nrf51822 sdk130 (central device) and nrf51822 sdk110(peripheral device). I want to get rssi value of the peripheral device using the central device without connection. Is it possible to read rssi value of peripheral device without connection?

Sure, each scanning event (when you receive ADV_xxx packet) has RSSI value in the event data structure.

It doesn't make much sense, the whole application is asynchronous:

• Get some interrupt or event => call some function (which might disable/enable more events).
• Wait for next event (whatever it is).

So just during boot set all initial events you are waiting for and then do in event handlers (button press or SD callbacks) what you want to do.
