RSSI value reading from peer without making connection

[ponlakshmi]

Hi i am having simple doubt.I am using the Nrf51822 as peripheral device and running beacon example from SDK 12.0.0.I am using nrfconnect in my mobile(Central device) to scan the beacon.My doubt is how the nrfconnect app reading the RSSI value from beacon without making connection to it. Is it possible to read the RSSI value without making connection.If it is possible means what are the functions are used.If it is possible means how the nrfconnect app is reading the RSSI value.

Hi,

The RSSI, received signal strength indicator, can be collected from any radio packet received. It's applied also for advertising packets. So connection is not needed to get the RSSI.

What do you mean by, "RSSI value from beacon" ?

RSSI = Received Signal Strength Indication - so are you talking about the strength of the received signal at the mobile, or do you somehow want to know what signal level the Beacon is receiving?

You missed the point: do you want the RSSI at the host (mobile), or the RSSI at the Nrf51822 (peripheral) ?
