If you have already explored mioty® technology and are now wondering whether the mioty® stack is the right fit for your products, this article provides the foundation you need.
The mioty® Protocol Stack is a highly efficient and exceptionally robust solution for both Low Power Wide Area Networks (LPWAN) and dense industrial networks. With its innovative Telegram Splitting technology, it sets new benchmarks in wireless data transmission and offers remarkable flexibility across application areas.
In this article, you’ll learn about the stack features, implemented standards, and the available stack packages.
Stack Features of mioty® Protocol Stack
The mioty® stack implements two protocol layers:
The standard stack package includes a flexible API for the software library, interfaces for externalizing security functions, a well‑designed Hardware Abstraction Layer (HAL), and a unified API look and feel.
In the modem application, all API functions are accessible via the supplied serial interface implementation, supporting UART, SPI and other ports with minimal overhead. This setup exposes the stack’s API 1:1 over a serial connection.
For highly security‑sensitive applications, the modem application even supports AES‑encrypted serial communication.
The stack also supports the integration of various types of non‑volatile memory, such as EEPROM, Flash or MRAM.
Through flexible interfaces, the stack can make use of hardware acceleration—for example for AES encryption/decryption or CRC‑16.
Depending on the hardware platform, the stack can operate in uni‑ or bidirectional Ultra Low Power (ULP) mode.
Interrupt‑driven state handling and the elimination of polling enable optimized energy consumption.
Which standards does the stack implement?
The mioty® Protocol Stack is an implementation of the ETSI Standard TS 103 357 and has been designed specifically for end‑device operation according to this specification.
Since 1988, ETSI has been a globally recognized institute responsible for developing standards in telecommunications and information exchange. With around 800 members from more than 66 countries, ETSI provides a reliable and internationally accepted foundation.
mioty® builds on this strong standard and defines the profiles EU0, EU1, EU2 and US0, enabling operation across different frequency bands in both Europe and the United States.
This ensures a consistent, cross‑border communication standard.
Functionally, the stack supports use with common embedded operating systems such as TI RTOS or Mbed, and it also supports bare‑metal operation.
In addition, the mioty® stack is fully prepared for operation in STACKFORCE multi‑stack environments, offering an easy‑to‑use, unified multi‑stack API.
Thanks to the well‑designed hardware abstraction, a mioty®‑capable radio chip is essentially the only hardware requirement for using the mioty® stack.
Das mioty® Stack Package
The mioty® stack package includes a precompiled stack library, hardware‑specific drivers, a serial interface, power management, and the two application folders “Example” and “Modem”.
- The Example folder contains a sample implementation for building custom firmware, showing how to integrate the stack library into your own application.
- The Modem application enables the creation of custom modem firmware using the provided serial interface and power management.
This allows the protocol stack package to support both chip architectures:
Single‑Chip Design
The protocol stack runs on the same microcontroller as the user application.
→ Uses the Example app (stack library only).
Two‑Chip Design
The protocol stack runs on a communication controller, while the application runs on a host controller.
→ Uses the Modem app to create custom modem firmware.
With the purchase of the mioty® stack, you receive:
- Protocol Stack: object code
- RF Drivers: object code
- HAL: source code
Additionally, 12 months of maintenance are included by default.
Various license models define further services such as extended support.
