If you are using BLE STACK, please use HCI_ReadRssiCmd in order to get RSSI value.

You can take a look at simple_central project to see how that's used.

RSSI stands for Received Signal Strength Indication, so what you are saying does not really make sense to me.
If you want to know how other devices see your device's rssi, then you need other device to send you the rssi information over the air.

It makes no sense for your own device to get your own rssi value...
