If I click *Communication*->*Add Link*, check *Advanced Options*, and change *Link Type* from *Serial* to *UDP*  the *Serial Link* options group does not change to the *UDP Link* options (showing a *Port* spinbox), and as a result when I click *Connect* I see an 'serial port... Error connecting: no such file or directory'. \r\n\r\nI was able to fix the issue by changing into Wifi mode (udp) and restarting QGC. After doing so, I am still not able to add a UDP link, but there is already one listed under the communication top menu item that has a *UDP Link* options group where I can change port and choose *Add IP* .\r\n\r\nSummary: Selecting *UDP* as the *Link Type* when adding a new connection should remove the *Serial Link* options group and show the *UDP Link* options group."}}
