Thanks for the info, I was just trying to get Avare connected.
Wanted to note that there is an updated version of XConn for MSFS2020. The required Simmconnect.dll is included in the download. Also of note; this version allows you to define the IP network broadcast address or a unicast address. With the broadcast address, multiple apps/devices on the local IP network can simultaneously receive the NMEA sentences.
