    some BACnet/IP devices won't respond to broadcast of 255.255.255.255. They only respond to local subnet broadcast requests. Hence the need to change the broadcast address to 192.168.69.255.
    I hope the above would help @techalton

    Thanks for sharing @cwangv. when I change the broadcast address to 192.168.69.255.im unable to scan any device at all

    @techalton
    You need to change the first three parts of the IP address to match you ip range.

    I am having different BACnetIP issue. In your case, most likely it is down to mango since only thing that has been changed is the mango version of software. Your field controllers would have still be the same.

    I have sent in my wireshark captures and am waiting for updates.

    Hi techalton,

    Yes, we were able to replicate the issue and reached out to the developer who was working on the changes between BACnet4J 4 and 5, which is predominantly work toward getting a BACnet BTL Compliance certification.

    The cause is that the device in question deviates from the BACnet specification with regards to the data type of its protocol version (section 12.11 specifies the protocol version to be an unsigned integer). The device in question provides a character string as its protocol version, The BTL specification stipulates how to respond to deviations from the specification, but I have not had access to the BTL compliance specification to ensure this is intended behavior, and the developer who did the work has not yet responded.

    Hi techalton,

    This is the git issue it is being tracked in: https://github.com/infiniteautomation/BACnet4J/issues/43

    Michel has responded and it looks like Terry has coded a prospective solution to this specific issue, but that it needs review / assistance to generalize the relaxing of the type checking in reading properties from other devices.

    @techalton I have a working solution but like @phildunlap said I am not planning to release it until it is fully vetted. However if you are interested in using a beta version I can build you a replacement jar for you to test with. This would involve replacing a jar file in the web/modules/BACnet/web/lib folder of your Mango installation and restarting Mango.

    @techalton I've released a new module for 3.6.x that should fix your problem. Please report back if you have any issues. Thanks!
