Wireless M-Bus Stack

Logo wM-Bus and OMS

The popular wireless M-Bus Protocol Stack by STACKFORCE leads to competitive products that are easy to install and maintain. The stack implements all protocol elements that are required for wireless M-Bus compliance and provides additional tool support. It is optimized towards a compromise of small footprint, excellent modularity and scalability, but though being feature-rich.

OUR 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 or 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.

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

Dynamic hardware timer adaptation including compensation in order to occupy only one hardware timer (and an RTC if applicable) for all wireless M-Bus related timings.

Support of any type of non-volatile memory

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

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!

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).

Commercial Features

  • First level support
  • Easy commissioning and configuration
  • Warranty and maintenance
  • Ensures a high quality product
