Low RSSI
Low RSSI
Since I bought the Taranis, I have seen that in many flights I get a
"low RSSI" warning, and sometimes even a "critical RSSI".
It happens with different receivers (X8R,* *D8R-II plus, D4R-II).
The altitude reached by my flying models (electric gliders) is never too high, not more
than 200 meters, with a horizontal distance of about 300-400 meters.
Even with critical RSSI warnings, I have never lost control of my planes.
I have attached a log file.
Many regards
Enzo

Re: Low RSSI
Spurious warnings will happen and are normal. You should only start to worry if it insists for several seconds.
RSSI is however relatively steadily low in that log, what receiver is it?

Re: Low RSSI
I know, but I still want to know what that particular log was done with... false warnings will happen with any, but the steady low I see here shouldn't...

Ha ha ha, you always find the right answer, don't you? shame on you.. go drink some coffee..

Re: Low RSSI
I get this as well (taranis and x8r) only a few flights and low and critical RSSI warnings with the plane within 100m, the plane is just a foamy trainer. I did a range test and found I got better RSSI with the taranis antenna pointing straight up but if I moved the rx away from pointing at the plane the RSSI dropped dramatically.
I don't know if the RSSI telematry actually works but this is worrying, I never had any range issues before even with the dx6i and ar6200. The most worrying thing is I have set the TX to zero throttle if I loose the RSSI and at the moment that could be as little as 200m!!
Not happy.......

Re: Low RSSI
I installed a new X8R in a composite glider on the weekend, a model that I have been flying for the last couple of years with my 9x, FRSKY DIY and a D8 Rx. Now, as described by others above, with Taranis I got almost continuous low RSSI warnings and frequent critical warnings when the model was within a few hundred metres. The Rx antenna locations are the same as with the D8 Rx and in that case I did get warning beeps from the module from time to time, but not often enough to concern me.
A range check barely gives 30m.
Is the Taranis warning system more sensitive than in the previous generation or do I need to check that there are no faulty components? Any advice welcome.

Re: Low RSSI
I have found it much more sensitive.
But also very location dependent.
Last week - I was flying an FPV model at a new site. I was getting constant rssi warnings at about 200m.
Same model at my normal site will go 500 with no warnings!
The other pilot had his quad kick into fail safe a few times at similar distance.
My conclusion... Massive interference, and taranis was just warning me!

Re: Low RSSI
hhmmm.... I wouldn't be able to fly with all those RSSI beeps..
The radio beeps for one reason, to warn you something is wrong.. If You ignore it, you are asking for it..
That is the point of having alarms in first place.. Better check what's happening..

Re: Low RSSI
The first thing would be to check at what level the RSSI warnings are set to.
Personally I consistently have a slightly higher RSSI with my 3 X8Rs than with D8s.

Re: Low RSSI
I fly at raf barkston Heath at weekends, I've never had any issues with spectrum, the majority in the club have never had any issues with their TX/rx (mainly JR) but I am getting low and critical RSSI warnings sometimes at 100m, are you telling me this kit is working???Rob Thomson wrote:I have found it much more sensitive.

If someone can't explain this issue, although I love the programming capabilities, it's going back.

Re: Low RSSI
Speak to the dealer you bought it from and tell him that you think the radio is faulty.. Hopefully he will sort you out..

Re: Low RSSI
There are lots of factors that could cause an rf message warning.
In my example, I only have a warning at the one site. Never at others.
In your case, if you get then all the time - then you should investigate.
Receiver leads OK? Tried changing the receiver? What's the model made of? Etc..
Possible it is an issue with the tx. But guess the obvious ones need to be checked first.

Re: Low RSSI
Thanks Rob, please don't think I'm getting at you, I'm not. The model is a max thrust riot trainer (foam), is there any special configuration for the 2 rx antenna, there is nothing in the instructions?Rob Thomson wrote:There are lots of factors that could cause an rf message warning.

I haven't changed the RSSI settings, low is set at 45 and critical is 42. The next time I go to the airfield I will do a real range test, you can see from one side of the site to the other and it's about 1000m ish.
If I'm still having issues I will contact my supplier to try another rx. The Other club members who primarily use JR said I was either very brave or mad to buy FrSky, I just hope they were wrong ....
Barry
Re: Low RSSI
I use frsky modules and receivers and never had problems.. in humid days is normal to have a beep or two when the model is to one side and/or low. never had consecutive beeping. when I do a range test, I always walk 100m or more without losing control in range test mode.. I think the 30m recommended by frsky aren't enough. anything less than 50 or 60 meters isn't enough to fly safely in my opinion
the antennas should be 90 degrees to each other. Avoid placing them near servos , metal, carbon fiber. we should also avoid running them parallel to cables and metal rods

Re: Low RSSI
Can you check something on your radio.
What is your country code set too?
Real long shot here - and I really cannot understand why...
On Monday and Thursday I had constant of warnings with my radio. So much so I was getting concerned.
On Saturday while playing with settings I noticed that I had at some point inadvertantly set my country region to america. I actually or member doing it - no more that a week or two back.
So today.. After setting it back to Europe... I went out with my FPV model.
To my surprise. Not even a blip! I took a 500m trip out, and everything was 100% perfect.
So why? Nothing bar that setting has changed!

Re: Low RSSI
The radio expects to see bigger waves that come all the way from USA
On the serious side that makes no sense Rob because set to US you are outputting 200 mw instead of 100 so if there was a problem with the radio you would expect to have more warnings when only using 100 mw.
Very weird indeed.

Re: Low RSSI
Agreed! That is why I am confused by it.
That's why I am wondering if maybe - something odd going on, and if anyone else can reproduce similar results.

Re: Low RSSI
As I understand the PXX protocol, the country code is only used when binding, so if you change it, and don't bind you haven't changed anything!

Re: Low RSSI
So on that logic.... The actual rf transmit power on the tx is in effect always retrieved from the RX?

Is it factual that the USA power output is greater than the European output?

Re: Low RSSI
Could be that the while thing is a red herring.
Makes no sense to me. Just strange that the warnings on the same model have vanished after the change.
Maybe just atmospheric conditions!

Re: Low RSSI
Rob, could it be that the day you had beeps was a humid day? I normally get some when there's a lot of humidity in the air.. Water has the bad habit of blocking very small radio waves .)
Maybe that's the reason there aren't many FPV submarines??

Re: Low RSSI
Interesting?
I flew many long flights with my Taranis and a D series d8r II receiver Friday at my normal location.
Saturday I flew it at a field in the country. I got RSSI low warning and beeps when my plane was a few hundred yards from me in a certain location. Never lost control. RSSI set to 45.
I flew many flights that days ldo going as high as 1100 feet and at distances that made the SkySurfer a dot.
I have many flights in the plane and receiver combo but recently added the Frsky precision vario that seems go be working normally.
I'm not used to RSSI alarms since setting it to 45 in the past.
My Taranis is set to USA.
I'll be flying at my normal field again next week and keep track of the RSSI alarm. Hopefully it's just the new location had something to do with this? It never stopped my flying. I'll take my skyboard 9x with a Frsky DJT along and substitute it if I get warnings at my local field.
How do I turn on the Taranis monitoring feature to record my RSSI flight values. It's a feature I haven't got to yet.
