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
Ohhh my gosh!!
I didn’t know about that.
Its easy easy hahaha.
thanks man..
