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.

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

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
