I want to compare some values of RSSI that I have obtained in a test that I have made with its corresponding theoretical value and to calculate this theoretical value I will use the following formula obtained here.
and I would like to know that parameter A , that is to say, the theoretical RSSI at a distance of one meter for a transmission power of 8, 0 and - 8 decibels for nRF52840 preview DK
On the other hand, I wanted to calculate the consumption of nrf52840 PDK when using the NUS example for peripheral and I got a graph similar to a periodic triangular signal, you know what the problem is?
