... 1- It turns on normally with battery inserted and without USB connection. 2- It does not turn on if I try to do this with USB connection and battery inserted. 3- If the remote control is off or without battery just connected via USB, it is recognized as a "STM 32 Bootloader" periphera...

The OpenTx version does not determine the RF module Firmware of the tx. You can flash the internal XJT of the tx to V2 Rf firmware and it should bind to the X6R you updated. If you had other rxs from the 'old' days they will have to have your 'old' rxs upgraded to RF firmware V2 and re-bound to get ...

Sorry I couldn't help.
I do not have any other suggestions.
I no longer have 2.3.11 on my PC. It worked for me in 2.2.4 and 2.3.14.
Good luck.

Did you do the 'Store calib. and hw settings in selected profile' on the bottom of the tab.
I would do that then save the .otx, then (re)open the .otx and check the 'Hardware' tab and see if the settings for LS and RS stuck.
If so, now see if that changes it so that LS and RS can be selected.

Have you looked in Companion at the Radio Settings in the Hardware tab to make sure LS and RS are defined?
If they are set to None, it would cause your symtoms.

Do you mean 2 switches? Sticks generally refers to the Aileron, Elevator, Rudder and Throttle/Flap/Spoiler inputs. Sticks have many more than 2 or 3 position. Switches are either 2 or 3 positions. If you mean switches: Combine to switches in a logical switch then use that logical switch to select th...

To tell you how to tell on your transmitter (tx) please explain what tx it is. Approximately how old it is would also be helpful...maybe. This is for the OPENTX firmware. To my knowledge there is no way to tell what the RF firmware version is on the tx . Most receivers (rx) do not have a method of d...

1.Older versions of OpenTx did not monitor the RTC clock battery. So you RTC battery may be ready to be replaced. 2. The SD card contents change when going from version to version. Specifically, the /SOUNDS/(language)/SYSTEM sounds and the version number which is in file 'opentx.sdcard.version'. ope...

Some info needed and info and troubleshooting hints: 0. What is the version number of OpenTx on the Tx firmware? ... and what is the version number of the Companion software? This should be of the form 1.x.y or 2.x.y 1. Have you tried a few different USB cables? and different USB ports? Some cables ...

How are you trying to get into bootloader mode? Sometimes people hold the power on button too long and the tx will not got into the bootloader. This video introduces the 3 ways firmware can be updated. The last resort method starts at around 9 minutes 30 seconds + or -. https://www.youtube.com/watch...

Two thoughts. 1. When a GPS is used the first time, it has no idea where in the world it is. It can take several minutes to establish where it is and start updating. (My Garmin inReach took about 20 minutes when I powered it on the first time. I was inside a wood building.) The longer it has been si...

Hi there Same problem with an r-xsr receiver Before it worked but after updating open tx, internal module and receiver I can't bind them. Hopefully we find the solution and if I can make it work I will post it right here What did you use for firmware for the Tx XJT module? If you used EU/LBT for th...

2.3.0 is the version of OpenTx firmware version. The receiver and transmitters have another piece of firmware for RF. Kilrah was referring to the RF firmware. This RF firmware can be downloaded from the Frsky-rc.com web site. However, before doing that you need to say how you are trying to change XJ...

I do not have an X9D Plus SE 2019 , but the version shown indicates that the firmware is for an X9D Plus. ..not an SE or 2019. I'm not sure this is important as I have not downloaded or used the X9D Plus SE 2019 firmware and SD, but believe the label should be OpenTx Plus 2019. Apparently the X9D+SE...

It has to have a SD card with the proper contents. Each release of firmware has different version numbers of the contents of the SD, There are some SD cards that are fake that have been reported in some units. These are generally 1 mb cards. So ask seller if the unit has an SD, the size of the cards...

The V8 series precedes my involvement with FrSky, so I know very little about it. It is an older rf protocol than X series ACCST I use. I believe it supports the older V8 protocol and the somewhat newer D8 protocol. The 2 series receivers I mentioned are D16 rf protocols. Your older tx (like mine) s...

Your tx does not support ACCESS rf protocol. SO you want an ACCST rx. A RX6R or G-R6X have 6 pwm output pins. The G version has a built in vario. (Some say that vario is not as good as the separate vario.) I use R6XR frequently. There are multiple versions of ACCST. Unless you upgraded your RF board...

Chances are you are using Ail sticks as in your flap mix, use the ail channel instead.
But there are other possibilities.
For best chance of getting help, post your .otx of the model.

In Companion for 2.2.4 and 2.3.9 both internal and external RF modules show 'FrSky XJT D16'.
On the tx my QX7 shows' D16' on 2.2.4 for internal.
Not sure if this helps.

Mixes are not time dependent !!! Your question is not clear. The best way to show what you are doing is to post an .otx of your model. (Along with what model and make ofthe your tx you are using and what the OpenTX version is.) The stabilizer is looking at both Ch11 and Ch10 except when channel 10 i...

For quite sometime, automatic discovery of sensors has not been available. The videos are often out of day. You must use Discover new sensors. If you connected directly to the battery you exceeded the input capability of A2. It expects only 0 to 3.3 V. You may have fried the A2 input circuit. You mu...

All levels of 2.3 should be compatible. I was afraid you had 2.3.x on the X9D 2019 and maybe 2.1.x on the Horus. Are you trying to convert on the tx or in Companion? I don't use a Horus so will not be much help. Good luck, out.
Posting your Horus .otx might be helpful.

It is probable that your Operating Systems are not at the same version level. It is even possible your Horus is running FrSkyOs rather than OpenTX. In order for someone to help it would be needed to know these pieces of info. In addition there are some inputs on the Horus that are not available on y...

Did you mean FreeLink? I don't know what FreeSky is other than the way to pronounce FrSky.

There are 'switches' which are 2 or 3 position toggle and there are navigation buttons/rotaries that generate EVENTS.
Events are auto updated by the Operating System, Switches must be polled to get current status.

I have an X9D and use 2.2.4. I can not reproduce your problem.
I'm on Windows 10.
What PC and version Operating system are you using?

No need to go to 2.3.5.
Going straight to 2.3.7 is fine, it contains all the fixes in 2.3.5 plus new changes.

Models may still need work. If you started with OpenTX version that was 2 or 3 versions older than 2.3.7. The conversion process provided is good, but generally speaking it is only really reliable to upgrade one step at a time. The format of the model data is stored in generally is changed each time...
