How to get RSSI value by reading the XBee DB parameter value?

In the documentation about “Signal strength and the RSSI pin” it is said the RSSI value can be obtained either as a PWM value on pin 6 or by reading the DB parameter value.
I have a difficulty with both approaches:

  • the oscilloscope is not getting any PWM signal on pin 6
  • I do not know how to read the DB parameter value.
    Can you help me to get a way to evaluate the signal strength?

I would suggest using the ATDB command.


The response will be in Hex values and in a Negative DB value.
