how to get the Rssi?

woosuk00

I am working on a simple project using Telink Mesh. I want to control the LED on the receiver side based on the transmitter's dBm level so that the LED only turns on when the signal strength is above -50 dBm.
I configured the RF Power as follows:

• Transmitter RF Power Index: RF_POWER_P0p04dBm
• Receiver RF Power Index: RF_POWER_N25p18dBm
  

As a result, the LED responds within a range of about 6–7 meters. However, I want the LED to turn on only within 3 meters. I am considering reading the dBm value using the RSSI to achieve this.
Q1. Is there a way to read the RSSI value?
Q2. If not, is there another method to make the system operate only at close range?

What I want is to obtain the RSSI value from the firmware.

There is a way to obtain the global variable value through the SWM signal line（SWM is the debugging interface for Telink chips）
