The STSW-WMBUS-GUI (wM-Bus demo suite) is a PC application to easily evaluate the features of the wM-Bus firmware running on ST Sub-1GHz devices.
The application is used for automatic, gas, water, electricity and heat meter readings.
The X-NUCLEO-S2868A1/STEVAL-FKI868V2 boards mounted on NUCLEO-L152RE/NUCLEO-L053R8/NUCLEO-F401RE boards create hardware platforms for testing a wM-Bus stack which communicates with PC using the VCOM protocol (with a default baud rate of 115200).
The compatible STM32 Nucleo boards must have the wM-Bus firmware loaded (for further details, refer to UM1904 for X-CUBE-SUBG1 on www.st.com).
The wM-Bus stack can be easily configured in different wM-Bus modes (sniffer mode and concentrator mode) and packets transactions can be captured using a GUI.
Using any terminal utility on PC, AT commands can be sent to the board to reconfigure wM-Bus stack in the desired mode.
The command/response can also be seen on the PC-GUI for the data concentrator unit by programming the board with the Conc-PC-GUI workspace selectable from the dropdown menu in the firmware project.
