Let’s just hope they will do this for new receivers in the future :) The R9MM is the first receiver Frsky has ever made that comes with “uninverted” SmartPort. If you have an F4 flight controller, and there is no dedicated SmartPort input (built-in inverter), then you will have to follow this guide and find the “uninverted” smartport signal for your receiver. enter these commands: set serialrx_halfduplex = ON However it’s not a problem for F3 and F7 flight controllers and you can connect it directly, just like this: Note that Frsky receivers SmartPort is an “inverted” signal, F4 flight controllers can’t read it directly. If you absolutely have no way to connect FPort, just go with the good old SBUS and SmartPort.

Simply connect the receiver’s SmartPort pin to a free UART TX pin on your flight controller.ĭon’t use soft-serial for FPort! It’s okay for SmartPort Telemetry, but it’s too slow for RC links.

The “ SmartPort” pin on your receiver becomes “ FPort” output.

Flight ControllersĪny F3, F4 or F7 FC with a spare UART should be able to run FPort. Make sure to update it to the latest Betaflight firmware: how to flash BF firmware. Note that by flashing this firmware, disables SBUS, you can flash the normal firmware again if you want to run SBUS. Here are my instructions how to flash Frsky receiver firmware. Most Frsky’s receivers support FPort now, just check in the above link, and see if there is a FPort firmware for your receiver. In order to enable FPort, you have to flash your receiver with the “FPort firmware”. Download firmware here: For example, the new R9MM receiver has a pin called “inverted S.Port” (it actually mean “inverted of the inverted”, making it non-inverted), but really they should just call it the F.Port pin. Hopefully in the future, Frsky will release F.Port only receivers with non-inverted outputs. This makes the F.Port signal inverted as well. ** Although the F.Port is a non-inverted protocol by design, currently the signal is still coming out of the SmartPort (S.Port) pin on the receiver, and the S.Port pin is normally inverted on Frsky receivers.

RSSI works automatically (no need to pass through a channel).

FPort is an uninverted protocol **, so hopefully we don’t have to worry about doing “ uninversion hacks” on F4 FC in future Frsky receivers.

save a UART port because SBUS and Smartport take up two separate UART’s.

cutting down cable management and soldering.

FPort combines SBUS and Smarport Telemetry into one single wire.

FPort is an “ RX protocol” – a communication interface between the RX (receiver) and FC (flight controller). FPort (possibly stands for “Frsky Port”?) is developed by both Betaflight Dev Team and Frsky, Why Is FPort Better?įrom now on, I will be using FPort over SBUS and SmartPort whenever I can, because:
