My RSSI is sitting between 85-95% (Quad sat right next to transmitter). Its only on 1 quad, so I know its not an issue with my radio or crossfire module. I have changed the anetanna out for a new one (No difference), I have also changed the crossfire RX out for a brand new one, so its not that either.
What else could it be?
Thanks

You may also have RF or electrical noise in the system. • Posts: 87 Threads: 15 Likes Received: 5 in 4 posts Likes Given: 43 Joined: Apr 2021 Reputation: 1 (05-Feb-2022, 06:30 PM)kafie1980 Wrote: How about the antenna and the placement of the antenna?
You may also have RF or electrical noise in the system. i.e. the antenna from the vista? I have changed the crossfire antenna out for a brand new one and it hasn't made a difference. I have tried the antenna from the crossfire both at the front of the quad and at the back. What could be causing electrical noise in the system? Sorry, I don't quite understand how I could change that or check for it? • Posts: 87 Threads: 15 Likes Received: 5 in 4 posts Likes Given: 43 Joined: Apr 2021 Reputation: 1 (05-Feb-2022, 06:30 PM)kafie1980 Wrote: How about the antenna and the placement of the antenna?
You may also have RF or electrical noise in the system. I think it has something to do with a recent upgrade to BF 4.3 (Although I have no idea why or how), but I have just flashed it back to BF 4.2.11 and the RSSI has gone back up to 100%. Come to think of it, all my other quads are still on 4.2.11. • Posts: 21,420 Threads: 597 Likes Received: 9,040 in 6,691 posts Likes Given: 1,428 Joined: Jun 2018 Reputation: 797 Do you mean LQ or do you actually mean RSSI (?)
Betaflight 4.3 uses CRSF V3 whereas Betaflight 4.2.x only used CRSF V2, so maybe that is the reason. Hard to say without some more testing. I had one of my quads on Brtaflight 4.3 RC2 but after the disarm bug surfaced I rolled it back to Betaflight 4.2.11, so I can't easily just check if I get the same behaviour unless I flash back to Betaflight 4.3 again.
Maybe try temporarily flashing one of your other Crossfire equipped quads to Betaflight 4.3 and see if the RSSI/LQ also starts behaving differently on that one too.
Out of interest, what version of the Crossfire firmware are you running? Posts: 87 Threads: 15 Likes Received: 5 in 4 posts Likes Given: 43 Joined: Apr 2021 Reputation: 1 (05-Feb-2022, 07:05 PM)SnowLeopardFPV Wrote: Do you mean LQ or do you actually mean RSSI (?)

That's a good idea, I will flash one of the other quads to 4.3 and see if I have the same issue. It is RSSI (Shown on the info panel on the setup tab in BF). RSSI & LQ still confuse me. • Posts: 21,420 Threads: 597 Likes Received: 9,040 in 6,691 posts Likes Given: 1,428 Joined: Jun 2018 Reputation: 797 Is this on a DJI FPV System equipped quad or an analogue quad?
Don't use RSSI with Crossfire. It is pretty much useless. LQ is the only RC link quality metric you need to worry about when using Crossfire. So just put the LQ element in your OSD and get rid of the RSSI element. • Posts: 87 Threads: 15 Likes Received: 5 in 4 posts Likes Given: 43 Joined: Apr 2021 Reputation: 1 (05-Feb-2022, 07:21 PM)SnowLeopardFPV Wrote: Is this on a DJI FPV System equipped quad or an analogue quad?

So just put the LQ element in your OSD and get rid of the RSSI element. Yeah its on DJI snow. I didn't realise it was useless. I will put LQ in the goggles, although I always find that a little harder to read. Thanks for the help. • Posts: 21,420 Threads: 597 Likes Received: 9,040 in 6,691 posts Likes Given: 1,428 Joined: Jun 2018 Reputation: 797 The DJI FPV Goggles don't support the native LQ OSD element, but you can still get the LQ value into the goggles by using the RSSI OSD element and overriding the RSSI value with the LQ value. This then passes the LQ value to the goggles as an RSSI value, so what you actually see in the RSSI OSD element is the LQ value. Maybe you've already configured it that way but if not then the following video walks you through how to set that up...

Thanks snow, I think I may have set it up using that video. I think I may wait on BF 4.3 until the official release and there are a few videos to watch. • Posts: 279 Threads: 94 Likes Received: 8 in 8 posts Likes Given: 269 Joined: Jan 2023 Reputation: 0 (05-Feb-2022, 07:46 PM)SnowLeopardFPV Wrote: The DJI FPV Goggles don't support the native LQ OSD element, but you can still get the LQ value into the goggles by using the RSSI OSD element and overriding the RSSI value with the LQ value.

Prof do the Dji still not support LQ ! • Posts: 21,420 Threads: 597 Likes Received: 9,040 in 6,691 posts Likes Given: 1,428 Joined: Jun 2018 Reputation: 797 (13-Mar-2024, 10:31 PM)Eyes.fpv Wrote: do the Dji still not support LQ ! If you're talking about the original (v1) DJI FPV System then no, the Custom OSD doesn't support the native LQ OSD element. However, if you want the LQ OSD element and more, you need to root the goggles and air units then install WTFOS. Once you do that you can then make use of the full blown Betaflight OSD including the LQ OSD element because WTFOS makes use of MSP DisplayPort to draw OSD elements onto the goggle screens. If you are talking about the DJI O3 Air Unit, that has always natively supported the full Betaflight OSD over MSP DisplayPort without needing to hack anything.
