Horus and Taranis firmware
Until further notice, DO NOT upgrade your Horus X10, X10S, or X12S firmware if you are using a XPS JR module with XJT mode. Also, do not upgrade to OpenTx v2.2.0 or later if you are using a Taranis.
It seems that with the Horus transmitters the updated FrSky firmware is checking for their module and deliberately not allowing 3rd party modules to work. OpenTx v2.2.0 has made some change to the XJT protocol that doesn't work with our JR module in XJT mode. I have ordered an external FrSky XJT module and some receivers for testing my theory with the Horus. I plan to update our Taranis with the latest OpenTx that has been reported not to work to see what the difference is. One thing to note about the Horus X10S. When it arrived it had v1.1.02 firmware on it. I upgraded it to v1.1.04 and it no longer outputs a XJT signal. I then put the original v1.1.02 firmware on it and it still doesn't output a XJT signal. So, don't experiment if you want to use our existing JR module, until I have figured this out! |

Not panicking yet
Waiting on delivery of a Taranis, just hope that it isn't supplied with the upgrade to 2.2.
If only we had the long awaited Tx, but I am too close to falling off the perch to wait any longer, so just put up with the hassles. Dirty tricks or protecting their investments? FrSky dirty tricks for mine. |

Upgrades
Jim,
Any more news yet about the upgrade to 2.2 on Taranis? |

I got a XJT module and found that it works with the X10S transmitter I have. The Horus firmware does not output frames, instead it outputs a continuous stream of data. It is going to be a nightmare to get that to work with our module. The OpenTx firmware does output frames and will work once I fix the code to support the change that was made to the XJT protocol between 2.1 and 2.2 for the OpenTx firmware. I am extremely busy preparing for AMA, checking the new X10+ boards, and making some firmware changes to the X24. So, it's going to be a bit before a fix is released. You can run any version firmware on the Taranis you like. So, if it does come with v2.2 you can always downgrade it to v2.1x until the fix is released.

What is XJT mode, I tried a XPS module in my Horus and it seems to bind to my receivers ok with firmware 1.4.04, can you explain what XJT mode is!

Taranis compatibility
Jim says Yes.
Haven't flown with the upgrade to 2.2 yet, but it works fine on the bench. |

Thanks Jim
Based on the fix, I have ultimately decided to move to an X10S radio and adding your JR module so that I can continue to fly the XPS receivers and X10+'s that I have. I'll likely migrate to all Frsky in the near future, but at least I'm not having to change out all my receivers right away. It's a shame the XPS3216 couldn't have been introduced by now as I regretfully (gradually) move away from the XPS platform. |

Ironically, since the release of the Horus radios we sold more JR modules in 2018 than we did in the previous 2 or so years. It seems that a lot of FrSky owners are moving to the XPS receivers because of their range, size, and super low voltage operation.

I too am regretfully moving away from the XPS system because it now is only operational with the open TX, Taranis and Horus transmitters. Don't want to do that but have no choice,
Bought a Taranis, kept it for ten days while I tried to program it and sold it Bought a RadioLink which programs exactly the same as my Futaba 10TCAP so no learning curve, but no XPS either. Shame |

Hi Jim,
I am eager to see if these 27 receivers you upgraded for me now work with my Horus. Regards from Graeme Marion in Sunny Queensland. |
