I would like to use T2 for fport. It then says” *** T2 can be remapped......”. If I’m going to use T2 for fport do I need to put that cli line in there or is that something else. I don’t see anything on T2 so I assume it’s not used and then the *** line comes in and confuses me. What needs to happen here?

You can just use the T2 pad for FPORT as-is. No need to remap anything. All F7 FCs automatically handle the inverted FPORT signal so you shouldn't have any headaches setting it up, other than the usual FrSky firmware minefield of course,

What’s all that jazz about soft serial tx1 stuff?

I see no good reason to use SoftSerial on an F7 FC. It is generally used as a workaround on F4 FC where the hardware UARTs can't handle inverted signals, or where there areas limited UARTs. Neither of those apply to an F7 FC.

Isnt F7 fc has more UART then you ever needed? No need to messing around with inversion stuffs.

Gotcha, just use as T2 and put Fport on uart2 in BF.

Yes, exactly that. Wire from the normal S.Port/F.Port output pin/pad on the receiver (not the uninverted pad) and then also run the following commands in the CLI to configure it correctly...

So you not only need to use the tabs for fport in BF but also configure with the code. Good to know I would’ve missed the code part. Thanks for saving me a week on BF!

Yes, the first two lines of those commands just configure what you can also do in the UI (switching on "Serial RX" for UART 2 in the Ports tab, and setting the Serial Receiver Provider to FPORT in the Configuration tab), then the other two command are telling Betaflight that the TX pad is being used for bi-directional data communication (by switching on the half duplex option), and that the signal coming into the FC is an inverted signal (by switching on the inverted option).
