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.

I want to continuously get rssi value of the peripheral device using the central device without connection. Normally I start the scan_start function using button_handler function. Then connection establish occurs. But I dont want to do that. I want to Connect automatically device without press the button (without button_handler function). And I want the device not to reconnect until it leaves the bluetooth signal range.(think like KEYLESS GO - Mercedes). Is it possible?
