E220 RSSI Values

[Eduardo]

Hello,

Frist of all, thanks for your libs 😀 it’s too useful.

I’m trying to understand the RSSI values that i get after a received message.

In the E220-900T22D datasheet the Receiving sensitivity is typical -147dB, but testing it with the modules 20m far it giving me 206(positive).

So if the sensitivity is -147dB i’m getting 206 and still working fine, maybe i’m setting the wrong configs.

thanks.

Hi Eduardo,
if you need dBm you must apply this formula
dBm = – (256 – RSSI)
the device not return directly dBm.
Bye Renzo
