Arduino SENDS:

Code Parameter Expected reply What does it mean Example
I <iButton ID> A, N IButton scanned I:33-000000000000
X NONE O Lazzzor shutdown button hit (eXit) X
P NONE P Ping! /Heartbeat P

Raspberry sends:

Code Parameter Expected reply What does it mean Example
A <username> NONE Authenticated A:OVERFLO
N NONE NONE Not authenticated (invalid Button) N
O NONE NONE Off (in response to X) O
P NONE NONE Heartbeat / PING P
E <Error> NONE Some Error occured E:Network down!
