NDN Arduino library for ESP8266 and more

esp8266ndn library enables Named Data Networking application development in Arduino environment. It supports ESP8266, ESP32, and Adafruit nRF52 microcontrollers.

• Doxygen documentation
• #esp8266ndn on Twitter for announcements
• ndn-lib mailing list for best-effort support

Features

Packet encoding and decoding

• Interest, Data, and Nack
  • Decoding recognizes both v0.2 and v0.3 formats
  • Interest encoding defaults to v0.3 format
• Signed Interest: 2014 format
• Naming Convention: 2014 format

Transports

• Ethernet: unicast and multicast
  • ESP8266: yes, requires lwIP 1.4 (in Arduino Tools menu select "lwIP Variant: v1.4 Higher Bandwidth")
  • ESP32: yes
• UDP: unicast and multicast
  • ESP8266: yes
  • ESP32: yes
• Bluetooth Low Energy
  • ESP32: server/peripheral and client/central
  • nRF52: server/peripheral only
• LoRa radio
  • ESP32: yes, only tested with Heltec WiFi_LoRa_32 board

Crypto

• SHA256 and HMAC-SHA256
  • ESP8266: yes, using BearSSL from Arduino Core
  • ESP32: yes, using mbed TLS from ESP-IDF
  • nRF52: yes, using CryptoSuite
• ECDSA
  • ESP8266: yes, using micro-ecc 'static'
  • ESP32: yes, using mbed TLS from ESP-IDF
  • nRF52: insecure, lacks random number generator integration

Forwarding

• ndn-lite forwarder
  • experimental, only tested with ESP8266

Application layer services

• ndnping server and client
• NDN-FCH client for connecting to the global NDN testbed
  • ESP8266 and ESP32 only
• UnixTime client for time synchronization

Installation

Clone this repository under $HOME/Arduino/libraries directory. Add #include <esp8266ndn.h> to your sketch. Check out the examples for how to use.
