## Detailed Description

Connection quality diagnostics.

# Synopsis

This class provide abstract connection quality diagnostics and counting. You should create instance of PIDiagnostics and on packet receive call function received(), on packet send call function sended(). PIDiagnostics calculates correct, wrong and sended counters, packets per second, bytes per seconds, immediate and integral receive frequencies and receive/send speeds in human readable representation. There statistics are calculates one time per period, by default 1 second. To calculate them you should start PIDiagnostics with function start() or pass true to constructor.

## ◆ Quality

enum PIDiagnostics::Quality

Connection quality.

Enumerator
Unknown | Unknown, no one packet received yet
Failure | No connection, no one correct packet received for last period
Bad | Bad connection, correct packets received <= 20%
Average | Average connection, correct packets received > 20% and <= 80%
Good | Good connection, correct packets received > 80%
