You can pretty much forget about the other two.
All you need to worry about with crossfire is the LQ value. >If you're using Crossfire then RSSI and dBm are pretty meaningless anyway. Well and what does that mean? Is it -45dBm? Aka FrSky maximal sensitivity is -45dBm? (Crossfire is -130dBm) Or what unit these 45 and 42 have?
>generally reflect what low RSSI values on FrSky receivers are the danger zones You can pretty much forget about the other two. If you're using Crossfire then RSSI and dBm are pretty meaningless anyway. Just set them to whatever values you feel appropriate for what receivers you are flying with. Every manufacturer implements RSSI in a different way. The same values don't necessarily mean anything for other manufacturer receivers. That's because OpenTX is heavily sponsored by FrSky.

What are these numbers? When I'm far away and RSSIdBm is -100 and RSSI 25% then the alarms are not triggered.Ĭould anyone explain me what these 45 and 42 mean? How they relate to BetaFlight OSD RSSIdBm or RSSI? Nice.īetaFlight OSD has RSSIdBm and it perfectly corresponds to Crossfire Nano 1RSSI sensor (I guess that it is just reading of that sensor)īetaFlight OSD also has RSSI (in %) which I also understand - 0% is -130dBm (minimum sensitivity for Crossfire Nano) and 100% is something like 0dBm (aka 1mW), this is also described in Crossfire manual:įor example when RSSIdBm is -65 then RSSI is 50% which makes perfect sense to me.īut what I don't understand are the default 45 and 42 RSSI alarms in OpenTX. I understand what is dBm it is simply a projection of mW onto exponential function and thanks to that it maps huge range between 1×1039 W - 0.056 zW to a human readable numbers (-192.5) - 420. I'm testing limits of my Tango 2 + Crossfire Nano.
