However, when I run, the output shows:

P: 192.168.107.247
    Device 17800
    Analog Input 0
    Multi-state Input 0
    Analog Input 1
    Trend Log 1
    Trend Log 2
    Trend Log 3
    File 0

I have been studying a BACnet frame from Wireshark, but I do not see any value.

How could I read values from a device?
Thank you very much!!
Regards!
