Overview

IoTivity is an open source software framework enabling seamless device-to-device connectivity to address the emerging needs of the Internet of Things,for more details, click https://www.iotivity.org

The demo is the detailed implement of IoTivity based on IoTivity-constrained. User can run different features on ESP32 via make menuconfig.

Features List:

• support IPv4 OIC server
• support IPv4 OIC client
• support IPv6 OIC server
• support IPv6 OIC client
• support RGB light control
• support interact with other IoTvity device

Hardware Introduction

The ESP32 Board control RGB light by the following configuration.

ESP32 GPIO	RGB light
GPIO4	R
GPIO5	G
GPIO21	B
GND	GND

user can change GPIO in lightbulb.c if needed.

Compiling and flashing the project

Compiling the esp32-iotivity is the same as compiling any other project based on the ESP-IDF:

1. You can clone the total project into an empty directory by using command:

git clone https://github.com/espressif/esp32-iotivity.git
cd esp32-iotivity
git submodule update --init --recursive

• make sure that you had cloned all the submodules. The esp32-iotivity project has the ESP-IDF and iotivity-constrained as the submodule.

2. Set the latest default configuration by make defconfig.

3. make menuconfig to config your serial port, WiFi ssid and password, IPv4 or IPv6, iotivity server or iotivity client, enable light control or disable light control, and enable or disable debug log.

• make sure that your router can support IPv4 multicast and IPv6 multicast.

4. choose two ESP32 board, one as iotivity server, the other as iotivity client, server board connect to the RGB light by Hardware Introduction.

5. make SERVER=1 flash monitor to compile & flashing & running the server.

6. reconfigure client environment by make clean && make defconfig && make menuconfig.

7. make CLIENT=1 flash monitor to compile & flashing & running the client.

More details are in the esp-idf README.
