This application is an example of how to test the MSTP callback functions on Linux. This application can be be ported to other hardware to test to ensure that it will support the requirements of BACnet MSTP.
This application is designed to work in tandem with Linux High Speed Serial Monitor
- Connect a USB RS485 converter to a Linux computer.
- Connect the USB RS384 [D+], [D-], [GND] to the unit under test [D+], [D-], [GND].
- Run Linux High Speed Serial Monitor on a Linux computer.
- Run the MSTP Callback Test on the unit under test.
