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)

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).
