Signal-to-noise ratio (SNR) in ESP8266

[luis_filipe]

Hello folks,

Is there any way to see the signal noise ratio in the module esp8266. I can see the RSSI of each access point, but after it is connected to the AP and send and receive packets how I can see the loss of packets in Db?

SNR: The signal-to-noise ratio is the ratio of the powers of a signal and the background noise:

Thanks in advance
