Follow the below instructions to install the Kenshi blockchain IoT SDK for your favorite platform.
To install the Kenshi IoT SDK for Arduino, go to the Kenshi IoT SDK release page on Github and download the latest release.
Then open the Arduino IDE and select Sketch > Include Library > Add ZIP Library... like the image below:
Now select the downloaded file and wait for the install to finish.
The Kenshi IoT SDK for Arduino has full support for ESP32 boards using the ESP32 native libraries. Follow the same instructions as Arduino boards to install the SDK for ESP32.
To bootstrap a Zephyr project with the Kenshi IoT SDK, you can run the following commands:
west init -m https://github.com/KenshiTech/iot-sdk.git --mf west.yml
west update
Alternatively, to add the SDK to an existing project, first find the path to your west manifest by running this command:
west manifest --path
Now open the west manifest file in the editor of your choice and add the following in the projects section:
# Kenshi repository.
- name: kenshi
  path: modules/lib/kenshi
  revision: master
  url: https://github.com/KenshiTech/iot-sdk.git
Now run:
west update
You can include the Kenshi SDK into your application by adding the following to your Zephyr project's configuration file:
CONFIG_KENSHI=y
Note that the Kenshi IoT library for Zephyr depends on the following (or similar) configuration options, which also need to be added to your project's configuration file:
# Enable DNS Resolver
# Needed to resolve api.kenshi.io
CONFIG_DNS_RESOLVER=y
CONFIG_DNS_SERVER_IP_ADDRESSES=y
CONFIG_DNS_SERVER1="8.8.8.8"
CONFIG_DNS_SERVER2="192.168.1.1"

# HTTP
# Needed to send and receive MQL requests
CONFIG_HTTP_CLIENT=y

# TLS configuration
# Needed for secure SSL communication
CONFIG_MBEDTLS=y
CONFIG_MBEDTLS_BUILTIN=y
CONFIG_MBEDTLS_ENABLE_HEAP=y
CONFIG_MBEDTLS_HEAP_SIZE=40000
CONFIG_MBEDTLS_SERVER_NAME_INDICATION=y

# Required for AWS root ca
CONFIG_MBEDTLS_SSL_MAX_CONTENT_LEN=8192

# Enable TLS
CONFIG_NET_SOCKETS_SOCKOPT_TLS=y
CONFIG_NET_SOCKETS_TLS_MAX_CONTEXTS=6

# Sockets
CONFIG_NET_SOCKETS=y
CONFIG_NET_SOCKETS_POLL_MAX=4
CONFIG_NET_SOCKETS_POSIX_NAMES=y
You can use your favorite HTTP or GraphQL client on these boards for communicating with the Kenshi Deep Index. Read the documentation here.
