IOTA Client Development Kit for Zephyr RTOS

This Software Development Kit(SDK) is a bundle of IOTA client library and Zephyr RTOS for embedded client development.

For more details please visit iota.c and Zephyr.

Hardware Requirements

The hardware requirements are depends on the use case, here are recommendations:

• 1MB Flash Memory
• 256KB SRAM
• True Random Number Generator
• HMAC-SHA Hardware Accelerator
• TCP/IP network stack with TLS support

Work with Zephyr

Please refer to Getting Started with Zephyr for setting up your development environment.

This is tested on b_l4s5i_iot01a and stm32f746g_disco targets at this moment.

Zephyr targets can be found in Supported Boards

Set ZEPHYR_BASE before using Zephyr build system.

$ export ZEPHYR_BASE="~/zephyrproject/zephyr"

Use west tool

# application configuration
$ west build -b b_l4s5i_iot01a -t menuconfig
# flash app to target board
$ west flash

Use CMake and Ninja

# Use cmake to configure a Ninja-based buildsystem:
$ cmake -B build -GNinja -DBOARD=b_l4s5i_iot01a

# configure and flash application to target
$ ninja -C build menuconfig
$ ninja -C build flash

Work with nRF-Connect SDK

Please refer to Getting Started with nRF-Connect for setting up your development environment.

Set ZEPHYR_BASE before using Zephyr build system.

$ export ZEPHYR_BASE="~/nRF-Connect-SDK/zephyr"
$ west build -b [email protected] -t menuconfig -- -DUNIT_TESTS=ON
# make sure ZTEST is enabled and stack size is big enough.
# CONFIG_ZTEST=y
# CONFIG_ZTEST_STACKSIZE=5120
$ west flash
