Hi Mani!

The RSSI (Received Signal Strength Indicator) is just a indication of how strong the signal is, and it might not be such a huge difference between 0 dBm and 4 dBm, specially at close range.

When I test it myself, I get a RRSI around 55 dBm for 0 dBm Transmit power, and a RSSI around 50 dBm for 4 dBm.
To be able to see bigger differences in the RSSI values, you can try to change the Transmit power between -20dBm and 4dBm for example.

Best regards,
Joakim.
