Building the IOTA CClient project on ESP32
If you are new to ESP32, please follow this document to build and run a hello_world example. Below we describe the CClient build.
- An ESP32-DevKitC
- USB cable — USB A / micro USB B
- ESP32 toolchain
- ESP-IDF (Espressif IoT Development Framework)
Step 1: checkout and initialize the project
This example project calls iota_client_get_node_info() to fetch node information and prints it out on the terminal.
$ git clone --recursive https://github.com/oopsmonk/iota_cclient_esp32.git $ cd iota_cclient_esp32 $ bash ./init.sh
Step 2: WiFi AP Configuration
Let’s setup the WiFi SSID and password for your project.
Note: ESP32 only supports the WiFi 2.4GHz channel.
$ idf.py menuconfig
Navigate to IOTA CClient Configuration and input your SSID and password.
Setup 3: Build and flash image
Now you are ready to build and flash the image to the ESP32. Please connect to the device via USB.
$ idf.py build
$ idf.py -p /dev/ttyUSB0 flash
Running the application
$ idf.py -p /dev/ttyUSB0 monitor
And you are up and running.
CClient is still an early development stage, but the core and extended APIs are ready to use, so you can:
- Test CClient APIs on ESP32
- Porting CClient to other IoT devices
- Report bugs on the entangled repo
