This is a Arduino Library for the ESP8266 12E.

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

RFC 7252 simple server library for Arduino.

• /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 .

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

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

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.

• 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.

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

• Server Side Working:

  • Methods
    • GET
    • PUT
    • POST (update working,creation not working)
    • DELETE (not working)
  • Ping
  • Observe (only 1 resource; only 10 observers)
  • Resource Discovery
  • Block Transfer (WIP)

• Client Side Working:

  • Methods
    • GET
    • PUT
