Stack Features

Flexible Interfaces

  • API for Application Layer for single chip solutions
    (API for other layers (e.g. DLL) possible)
  • API for externalization of security functions
  • Well-formed Hardware Abstraction Layer (HAL)
  • Available as library

Network processor

  • Well-proven serial interface with minimal
  • All API functions available via serial interface
  • Serial interface supports UART, SPI, I²C, …
  • AES encryption for serial interface

Support of hardware acceleration

If provided by the platform, the stack supports the use of hardware acceleration, like:

  • AES de- / encryption
  • CRC-16
  • De- / encoding of Manchester, 3 out of 6, ...

Wireless M-bus mode and device type selection

Selection of mode (e.g. T and C), direction (unidirectional / bidirectional) is possible ...

  • during compile time to shrink the memory footprint.
  • during runtime to permit flexibility at any time in the field.

Flexible Software Timer

In order to make use of only one hardware timer for all wireless M-Bus related timings, the stack can perform compensation for synchronous interval timing as well as automatically drop packets in case of a large mismatch.

Support of any type of non-volatile memory

  • EEPROM, Flash, MRAM, …
  • Internal / external (e.g. connected via SPI)

wireless M-Bus stack architecture

Classical or with LPWAN technology

Our wireless M-Bus Stack is not just available as the standard version, compliant to EN 13757 and OMS specification as meter or collector, but also in combination with mioty® (M-Bus-over-mioty® stack) or LoRaWAN® (M-Bus-over-LoRaWAN® stack). Therefore you do not only benefit from the well-proven, well-spread and popular wireless M-Bus protocol, but also from the advantages of the modern LPWAN (Low-Power Wide Area Network) technologies. They enable larger transmission ranges, which is especially of interest for applications like Smart Metering and Smart City.

Beyond wireless M-Bus

Wireless M-Bus surely is the standard protocol for metering purposes. But wouldn't it be great to enhance the flexibility of your network and to be able to switch between wireless M-Bus or OMS and also LPWAN technologies like mioty®, LoRaWAN®, Sigfox and others? We make it possible!

Multi Stack

Our Multi-Stacks offer the possibility to choose between several stacks and radio standards, such as mioty®, LoRaWAN®, wireless M-Bus, OMS, Sigfox and others. This flexible solution allows you to achieve maximum usability when you connect your product to the Internet of Things (IoT).
