Your benefits with our stack package
Well-designed API (Application Programming Interface)
Easy to use API well-proven and used for several low-power radio stacks by STACKFORCE
Platform Interface now available as source code
- Customization and fine tuning of platform driver
- Customization of radio settings (e.g., frequency)
Optimized power consumption
Power consumption is optimized through interrupt driven state management and the exclusion of polling.
Strengthen the future viability of your devices with this stack

USE CASE: Fixed networks and walk-by/drive-by
Standard communication setup and fallback solution
In IoT applications, reliable data collection is essential. In this video, we’ll demonstrate how a Dual Protocol Stack – featuring OMS®/Wireless M-Bus combined with either LoRaWAN® or mioty® – creates a robust communication setup with a built-in fallback solution.
With this Dual Stack approach, your IoT system has both a primary communication network and a backup option. So, if the main network connection goes down, data can still be reliably collected via the alternative protocol. This setup ensures stable, continuous data transmission even during unexpected network disruptions, allowing your operations to run smoothly without data loss.
