Author Topic: Different results upgrading to OpenTx 2.2.3 and new Flex firmware on R9 system  (Read 743 times)

A friend and I have recently experienced 2 different results from upgrading to OpenTx 2.2.3 and the Flex firmware

Both updated the latest Flex Firmware to the R9M Module and R9 receiver dated 13th Feb 2019 which were R9_FLEX.frk and R9M_FLEX.frk

The difference was slightly different versions of the OpenTx 2.2.3 software both of which were installed at about the same time but from different laptops running Companion.

The first was done with 2.2.3 dated 8th Jan 2019 and had an option for 868MHz which then allowed selection of the full flex power output of Auto <=1W (see screen shot attached) plus telemetry selected when binding.

The second was done with 2.2.3 dated 23rd Jan 2019 which only allowed EU to be selected (not 868MHz) and this had a max of 500mW power (not the Auto <=1W).  In addition it did not offer any telemetry options when binding

Both seem to be working fine on low power range checks.  Has anyone any ideas?  Have the EU clamped down on 1W?

"The first was done with 2.2.3 dated 8th Jan 2019 and had an option for 868MHz which then allowed selection of the full flex power output of Auto <=1W (see screen shot attached) plus telemetry selected when binding."

  The 868mhz option has always been limited to less than 1 watt maximum output as far as I know.

    Auto <=1W......This means (less than) 1W.....What it doesnt tell you is how much less than 1 watt. For instance, it could be 988mw.

  The best I can get from my R9MM receiver (using the latest Flex Firmware) and limited to 500mw Max is around 2.4 kms before the RSSI starts dropping like a stone.

 500mw @ 868mhz is a LOT of RF power.  For example, an XM Plus can easily achieve up to 6 kms on 2.4G with only 100mw of TX power.
 
   I'd be more interested to see what a real range test brings TBH.

Yes, allegedly the flex offers an output of from 100mW up to 1W depending on RSSI, but as others have said, the RSSI signal from the Rx will be lost well before the Tx output so is pretty meaningless.  I guess it will flex up to 1W fairly soon after it gets beyond a Km or so, then the Tx will announce "telemetry lost" but there will still be control - we can live in hope!!

  Agreed, but to be fair, most serious FPV pilots will be using an Autopilot with the benefit of an OSD. This means Telemetry is redundant and not a lot of use TBH.
  My R9M tests were done using an OSD with RSSI available numerically all the time. The most notable difference the Flex Firmware made was the stability of the RSSI. Instead of the numbers bouncing all over, they became smooth and more predictable.
  Try flying out beyond 3 kms and Id be interested to see the results....I have shelved my R9M system, it simply does not have enough range.

They have been changing the protocol as they go along so different features were changed/ optimised / dropped while debugging so each firmware varies.

To be honest I couldn't tell you which one to both go with, by rights it should be the latest version, but with R9's evolution new doesn't necessarily mean better.

They really have completely screwed up with this system,  it's really not fit for purpose at the point it's at right now. Mine has been placed on a shelf until they get their act together.

Thanks.  I fly fixed wing without any autopilot or RTH so as soon as the wind drops a bit I will do some progressive range proving with a nice stable model like the Easy Star before getting the faster models out!!

I will report my findings........

  Mine works fine too....It just doesn't have any range much over 3 kms.

  I am yet to see anyone try it with long range video onboard too...That said I can think of ONE person who is getting a very different story...:

 This flight is on early Fixed Firmware @ 200mw and the RX is an R9MM.....?

Thanks for that info - sounds like the R9 system as a whole is now maturing.  Olivier C seems to have had a lot of success from looking at his videos.

I think I have found out why my friend and I had different options on the OpenTx - he hadn't selected the FlexR9 option when upgrading to 2.2.3 using Companion and hasn't got the flex option.  I did select it and have the full up to 1W Flex plus telemetry

On the plus side we both seem to have some good range tests and are hoping to fly on Monday for some real tests!!  Actually I don't really want to do excessive range, I just want to be confident I can go to 2-3K without worrying that I will get a failsafe

Got out today and in between showers got to 2.2km at which point the RSSI indicator on the Tx was showing 4 bars and just dropped to 3 bars when I turned according to my incompetent observer.  This means it was at about 80% at 2.2km. 

Before doing the upgrade to 2.2.3 and flex I would have expected short failsafes at that range, so I am reasonably happy.

Not sure exactly how the RSSI will work at longer distances when 25mW from the receiver is so much less than up to 1W from the Tx, however as long as it works now I donít really mind!!

Got good eyesight has he?

Furthest I've got so far is 4km on 100mw.  There was room to go further, but video was the main limitation.

Yes, my video was OK on 5.8GHz and could go a bit further.  Iím using a 7db patch on my goggles which seeems to work really well.  Certainly f you turn round so only the Omni is receiving, there is loads of static.

Iím getting more confident - which usually means disaster!!!  LOL

I did get a VAS/IBCrazy 5 turn helical, which was a big improvement over the menac pico patch I was using for video.  It's worth thinking about a helical for longer range video.
