How to use the Sport protocol ?

Before proceeding with the first step, we need to confirm that the INAV firmware version is 6.1.1. Following this, proceed with the steps in order for SOFTSERIAL1 to appear.

Step 1: Open the "Enable CPU based serial ports" option on the Configuration page.

Step 2: Enable the SmartPort feature for SOFTSERIAL1 on the Ports page.

Please connect the S.PORT of your receiver to TX2. F.PORT and F.BUS require a direct connection to the flight controller. However, to ensure stability, our flight controller has resistors added to its serial connections. Therefore, it cannot support F.PORT and F.BUS connections.
