SPECIFICATION

EnOcean Serial Protocol 3 (ESP3)

V1.16 / Jun 14, 2011

 

This document specifies the EnOcean Serial Protocol 3.0 (ESP3).

The ESP3 defines the serial communication between a host and EnOcean modules (based

on Dolphin Platform). Hosts are external microcontrollers or PC’s incl. software tools.

The physical interface between  a  host and  a  EnOcean  RF module  (UART)  is  a 3-wire

connection (Rx, Tx, GND / software handshake / full-duplex), modelled on RS-232 serial interface.

ESP3  enhances  ESP2,  adding  future-proof  structures  and  extending the data  content.

The new functional properties are:

  • Transmission of the received  radio  signal strength, and number of the received subtelegrams.
  • Future requirements can be realized  flexibly with the packet group «Optional Data»,  without violating the compatibility.
  • Improved data security and consistency by CRC8 Data verification.
  • Higher reliable ESP3 packet detection at serial byte stream.
  • Approximately seven-time higher baud rate.
