Ease of integration of LoRaWAN®
into the OMS® world
Pre-certification on reference
hardware platform
Your benefits with our stack package
Exchange of standardized OMS® data points
Facilitate the reuse of existing systems for data processing through the exchange of standardized OMS® data points.
Platform Interface now 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.
Strengthen the future viability of your devices with this stack
Protocol Stack Features
OMS® v4.5.1 for End Devices
- EN 13757-3/-4/-7 (Wireless M-Bus) compliant Protocol Stack for End Devices
- Operation modes S, T or C
