I seem to be in a pickle, I just updated my X8R rx with the latest Accst-2.1.0 lbt and my Radio Taranis X9D+ was already on version 2.3.9. I now find they will not talk to each other crying I just checked Frsky site and spotted a comment ( History firmware download not compatible with v2.x.x ) angry does that mean I have had it ?

I looked for an older version and could not find one, there seems to be only one download to chose which covers the X6R and X8R receivers in the discontinued section.

It is all a bit complicated now.

Sounds like you are on OpenTX 2.3.9 V1 of the TX firmware.

V 2.3.9 refers to the version of OpenTX and not the radio firmware, which will probably be V1.

If you have not updated the TX to V2 of the firmware then you need to click on the download on the history bit.

That will take you to the correct page to download the firmware. it will automatically download the older V1 RX firmware.

It is possible to flash an RX from the newer to the older version. I have done this myself.

 

Hope that helps.

I didn't know there was a v2 firmware, I quite liked this radio before the other protocol came out. It's getting a bit confusing. I cannot understand why I was having trouble with low rssi signals when range testing all of a sudden and all I did was update the Taranis, so I thought I would update the X8R. I wish I had never bothered cryingangrysurprise

PM me your email and I will send you the file you want.

Are you running FCC or LBT?

 

I would guess LBT.

 

Or download it from this link.

Im confused, I thought the Tx firmware was opentx ? Whats V1 and V2 how do I tell what I have got ? All I have ever done is update the opentx version. Will this mean I have to update all my receivers disgust

No, you will not need to update all your RX

If you are running OpenTX v2.3.9 you have the latest OpenTX.

Forget V1 and 2 for now as you have clearly not updated that.

Download the file from my link and flash your RX with it. That will put it back to the V1 firmware.

You may need to rebind, but probably not.

I just looked at the readme file in Taranis and it says boot version the same as opentx. BOOTVER opentx-x9d+2.3.9-otx (60e1edc1 )

You have not updated your Taranis other than OpenTX to 2.3.9 correct?

If the answer is yes then just flash the RX with the file from my link. All should be good.

Back in about 30 minutes.

The Taranis has two items of firmware, the operating system (openTx in your case but could be erskyTx), and the (internal) module firmware. If you update the Rx to V2.1.0, then you need to update the module firmware to V2.1 as well. If you do update the Tx module, you will need to update all your receivers to V2.1 as well. V1 module/receiver firmware is not compatible with V2.1 module/receiver firmware.

The reason for the V2.1 firmware is a problem was found with the V1 firmware. Under certain conditions, the Rx could lose the radio link for up to 0.9 seconds, and during this time it may also cause one, or more, servos to move to full deflection. Since if this happens near the ground it could cause the model to crash, V2.1 has been released that fixes the problem. It could not be completely fixed by just changing the V1 firmware (although V1 can be made to lose the link for only a very short time and only have the servo glitch for that time (less than 0.1S). I have done that for the firmware I have that allows a D8 receiver to operate in D16 mode.

I can confirm the loss of radio link with my Riot, I'd just taken off about one mistake high I tried banking to the right and it went left. Then regained signal as it hit the deck crying

A partial guide to updating your firmware to V2

**LINK**

Remember once you do the TX then ALL RX need to be updated to V2 as well.

I presumed you wanted to stay on V1

Are we talking about the Tx bootloader thinking

Kevin's link didn't do it for me, but this video is what enabled me to get the job done. As has been mentioned, the v2 update is of the FrSky firmware, not the OTX operating system, and once done on the transmitter needs to be done for all the receivers you're going to use with it. Doing the receivers is simple, though one needs to check carefully that every model has transferred correctly, as some people have noticed small changes such as some senses reversed compared with v1. I've been flying models with updated RXSR and X8R receivers for a few weeks now without any problems. I must admit I was struggling with an S8R, but I think I got it sorted (on the bench anyway) yesterday.

. . . . I must admit I was struggling with an S8R, but I think I got it sorted (on the bench anyway) yesterday.

I'm giving up on the S8R for the moment. Today my TwinStar took off as normal, joined the circuit and throttled back to cruise as normal, and then went haywire and crashed after some amazing aerobatics, none of which were instigated by me! Structural damage is not too bad and, on recovering the model, all surfaces were working correctly and a range check passed okay. At the time of the crash neither stabilisation nor self-levelling mode were activated.

The previous week I had aborted the TwinStar's maiden S8R v2.1.0 flight because the pre-flight check showed that the rudder went to full deflection when stabilisation mode was selected. Since then I re-flashed the v2.1.0 firmware and reconfigured the S8R in 'Quick' mode, and all worked well in the workshop, and in the pre-flight at the field today.
