OMS®/wM-Bus + OMS® over LoRaWAN® for End Devices

Multi Stack

End device

Seamless switching between stacks ensures maximum flexibility

Remote meter reading enabled by fixed networks and drive-by/walk-by

Ease of integration of LoRaWAN® into the OMS® world

Pre-certification on reference hardware platform

OMS® + OMS® over LoRaWAN for End Devices

Smart utilities need more than just a good network. They need a great connection with the best possible flexibility for different application scenarios. Why not offer your customers exactly that? By integrating our dual stack for end nodes, you enable your customers to use interoperable devices with the latest

  • OMS® v4 and
  • TR06 specified communication.

OMS® over LoRaWAN® defines how OMS®-compliant data packets can be exchanged bidirectionally via LoRaWAN®. The dual stack enables remote meter reading via fixed networks as well as walk-by/drive-by to ensure 100% data collection.

Your benefits with our Protocol Stack Package

Exchange of standardized OMS® data points

acilitate the reuse of existing systems for data processing through the exchange of standardized OMS® data points

Plattform interface available as source code

Customization and fine tuning of platform driver​
Customization of radio settings (e.g., frequency)

Optimized footprint

When using a dual stack compared to using two single stacks, the memory requirement is significantly optimized

Technical Information

Supported Specifications

OMS® v4.5.1 Protocol Stack compliant according

  • EN 13757 (Wireless M-Bus) Open Metering Standard (OMS®)

OMS® over LoRaWAN® Protocol Stack compliant according

  • OMS® over LoRaWAN® (acc. to TR06 v2.0.8) Specification

STMicroelectronics STM32WL5/STM32WLE5: Nucleo-WL55JC

The code sizes described above specify the typical required memory for operating the full featured protocol stack as a library including related drivers. Values based on reference hardware STMicroelectronics STM32WL5/STM32WLE5: Nucleo-WL55JC. The RAM requirements for LoRaWAN® FUOTA are not included in the values, as these are very dependent on the application.

Frequently asked Questions

What is included in the STACKFORCE software package?

Our Protocol Stack package includes everything you need for integration:

  • Precompiled stack library
  • Hardware-specific drivers
  • Serial interface (UART, SPI, etc.)
  • Power management
  • Example applications for quick integration
  • Documentation

The Protocol Stack itself is delivered as object code and cannot be directly modified. The platform interface (including HAL and RF driver integration) is provided as source code. This allows you to:

  • Adapt the platform driver to your target hardware
  • Configure specific radio settings such as frequencies
  • Optimize driver behavior
  • Add your own components such as security and timers

For further adjustments to the stack itself, we are happy to support you with specific development services.

Yes, that’s possible. In addition to our standard solutions, we offer customer-specific extensions of our Protocol Stacks. This enables us to implement your specific requirements so that the stack integrates seamlessly into your system environment.
We are happy to check compatibility with your specific hardware. If your hardware meets the minimum requirements for running a Protocol Stack, porting is generally possible. We can discuss the porting effort with you or provide our Platform Porting Guide so you can perform the porting yourself.
Yes. You can request a free evaluation license and test the software in your target environment—without obligation and risk-free. More information about the evaluation offer can be found on our website under: Evaluation License.
