Running the Wireless M-Bus application

Figure 22. Selecting configuration

Flash the concentrator board using WMBUS_SDK workspace. The two configuration

available for concentrator are:

SPIRIT1_wmbus-gui-169: Concentrator FW for 169 MHz frequency band

SPIRIT1_wmbus-gui-868: Concentrator FW for 868 MHz frequency band

Make sure that meter and concentrator devices are programmed with same

configuration i.e. if meter is programmed with 169 MHz configuration then same

configuration should be used at concentrator side also.

Connect the concentrator to WMBus PC GUI: WMBus & Sniffer for SPIRIT1. Follow

steps described in section 4.4 to use GUI.

Different meter types are supported in WMBus. For example:

Electricity meter=0x02

Gas meter=0x03

Heat meter=0x04 and so on.

User can set meter type using following: “Project tab -> Options -> C/C++ Compiler ->

Preprocessor” option.
