Read rssi on data received after connection in S120

[sowmya]

Hello,

I need to know does nordic S120 stack gives the RSSI value on receiving data from peripheral? Currently I am able to get the peripheral RSSI on peripheral device. But in general, the central has to update the signal strength of the data received. Is this is possible in S120? Or is there any settings has to be done to read RSSI of the data received.

After connection only I need to get updated RSSI not while advertising.

sd_ble_gap_rssi_start(...) and sd_ble_gap_rssi_get(...) works in the same way for the central as for the peripheral.

Yes I am using the same method on peripheral device. But in Central device, after connecting multiple periperals, when I get RSSI_CHANGED event, it will be not having the information of the peripheral device. Can I get to which connection/slave the RSSI is?

The connection handle should be in p_gap_evt->conn_handle.

Thank you Ole. Currently I am connecting 2 peripherals and started RSSI method on central, and it is assigning the same connection handle for both peripherals. So I planned to check by peer_address , but the peer address field is overridden by RSSI values since its in union. Is there any other way to get to know for which peripheral the RSSI belongs to?

The connection handles should be different. I just tested with the multilink example to be sure.
