thingTronics ESP8266 12E Arduino Library

This is a Arduino Library for the ESP8266 12E.

ESP-CoAP server/client library for Arduino

This repo contains CoAP protocol for operationg ESP-12E as CoAP server and as CoAp client.

IETF CoAP RFC 7252

RFC 7252 simple server library for Arduino.

Repository Contents

• /examples - Example sketches for the library (.ino). Run these from the Arduino IDE.
• /src - Source files for the library (.cpp, .h).
• library.properties - General library properties for the Arduino package manager.
• library.json - General library properties for the Arduino package manager in JSON format
• keywords.txt - Contains the keywords for Arduino IDE.

This lightweight library source code have only 4 files. coapServer.cpp, coapServer.h, coapClient.cpp, coapClient.h .

Example

Some sample sketches for Arduino included(/examples/).

• coapserver.ino: simple server endpoint url callback sample.
• coapclient.ino: simple client response callback sample.

How to use

Download this source code branch zip file and extract to the Arduino libraries directory or checkout repository. Here is checkout on Ubuntu.

cd $HOME/Downloads/Arduino/libraries/
git clone https://github.com/automote/ESP-CoAP
# restart Arduino IDE, you can find ESP-CoAP examples.

working with CoAP server

• Upload the server example code to ESP-12E and open Serial Monitor to get the IPaddress of ESP-12E(server)
• Run the coap client(web browser) with following URI coap://IPaddress:default port number/resource, to connect to ESP-12E server.

working with CoAP client

• Upload the client example cose to ESP-12E, check the working by taking ETH Zurich as server.
