FrSky LUA script for switching between EU-LBT & FCC

[badger1]

does anyone have any experience (& a copy) of this?

I need to buddy-box my X9D (FCC) to a friend's (EU) to teach him to fly his planes (EU Rx's).  normally we could just swap Tx's so his EU one was Master, but it's probably not such a great idea at the moment.

we will be needing a 3m buddy lead too

I use it and it works fine. You do have to power cycle after changing modes. Curry Kitten on YouTube did a video on it with link to script. If you can't find it let me know and I will dig it out

The link to the lua script is on Curry Kittens blog down the page here https://www.currykitten.co.uk/using-spi-receivers-with-an-lbt-eu-radio/
Video is https://youtu.be/kNpXQrwUlTc
Just remember to power cycle after you change modes.

thanks ched, much appreciated

No problems mate.
I assume you don't have an Access X9D do you? Some of the newer radios have PARA wireless training system built in that uses bluetooth between radios so no trainer cables.

[badger1]

no, my X9D is so old it's not even an X9D+

I was thinking of getting a new FrSky Tx this year, but the debarcle with ACCESS put me off.

To me the issue with ACCESS depends on if you have lots of older rx and if you have stuff with spi rx. If not then ACCESS is not an issue really. ACCESS2 on the other hand is more of an issue, no idea why FrSky brought out ACCESS2 it's just to confuse things even more.
I read somewhere a while ago that the encryption on ACCESS has already been broken so 3rd party rx will, if not already, be available!
Having multiple protocols is bad enough but adding in EU-LBT and FCC to the mix just gets silly.
I can't understand why FrSky didn't include the FCC/EU lua script by default.

I don't think FrSky were wrong in trying to protect their business by effectively trying to stop 3rd party rx but what was wrong was them telling retailers they can't sell FrSky and other (Jumper etc). Especially when they use Open Source FW that, while they might have contributed to they can't say who can and can't use the software...

If you have no issues with your tx I would stick with it but download the D8 and D16 fw for every receiver you might buy so when they stop the links it doesn't matter.
I think you can upgrade to hall effect gimbals which might be good as the resistive ones do wear out.

[badger1]

I've rather lost track of the more recent FrSky stuff - I'm sure you're right about ACCESS2.  I had decided not to get a new Tx because I thought they couldn't talk ACCST, but it sounds like this isn't the case - I should probably watch the CK YT video that you kindly linked to before I ask any more stupid questions - lol

[ched]

It is a bit complex. Access radios can use ACCST D16 but not D8!!!!!

[badger1]

I just watched the CK video & the issue seems to be with ACCST2 & this alleged "bug" which only about two people in the entire world have ever seen (which does ring a bell).

also the LUA switcher only works with ACCESS radios - not the legacy ACCST-only ones which do seem to need the RF modules flashing.

that said, now I know that ACCESS radios do talk ACCST, I could be tempted to do my bit & help get the economy going again. 

maybe a multiprotocol module too so I could switch between FCC/EU on the X9D and run D8 on a shiny new QX7(S) ... hmm

Thanks for posting that. In all that I have read about v2 my brain had transposed ACCSTv2 to ACCESSv2       
It does make much more sense now     
Why would they bring ACCESSv2 so soon after v1? But bringing out ACCSTv2 to add encryption by the back door makes so much more sense   
STUPID ME     

Thanks for the post most helpful....

I believe ACCESS radios only do D16 in ACCST mode!!! The D16 was only introduced after lots of people complained that legacy stuff wouldn't work. I guess frsky didn't include D8 as it would enable the 3rd party rx to continue to work and that was what they were aiming to stop.
I think you could run FCC/EU using lua app on QX7 (Access version) and using a multiprotocol module in the QX7 you could run D8!!! So everything in 1 radio....

np - FrSky do seem to be trying their best to be as confusing as possible at the moment.

thanks ched - what I meant was, with a MP module I could either use it to switch between FCC & EU on my X9D, or run D8 on a QX7(S).

I think we might just keep it simple & he can fly my Tundra (FCC Rx) with his EU X9D+ slaved to my FCC X9D.

now that I know the ACCESS radios can do ACCST I am quite tempted by a QX7/QX7S - is the difference just the wireless buddying & Hall-effect gimbals in the 'S'?  of course, then an R9 module is only another £15 ... damn you FrSky

Keeping it simple is always good to me 

I think the differences are the gimbals, wireless stuff (training, plus there is supposed to be an app that does telemetry but it seems to get very bad reviews), I think it also comes with a battery and charger, better grip material and nicer switches (angled a little to aid people who pinch sticks) and gimbal sticks.
quadcopters.co.uk and hobbyrc.co.uk show a nice QX7s with a carbon look that seems same price as standard ones  Not that either of them have stock!!

R9 £15 where?????

[badger1]

thanks ched

R9 £15 where?????

https://www.t9hobbysport.com/frsky-taranis-q-x7s-access-2.4ghz-transmitter

£15 only when you buy it with the Tx - they do claim to have stock though

Yes, well, ACCESS is all about getting people to lock into their gear and prevent compatibles.

Which is a complete about face to when they were starting out by deliberately undercutting Futaba massively with their FASST compatibles.

Sauce for the goose?, etc, etc....................

Didn't they also copy a Futaba radio to base the X9D on?

The R9 lite is only £18 on it's own   
The link too the QX7S doesn't include battery or charger the ones listed at quadcopters and hobbyrc both come with batteries and charger!! The t9hobby... does have a 18650 adapter though. So really depends on what battery system you are used to plus t9hobby.... are in stock

JR.  funnily enough someone had a JR Tx based on the same mouldings at our field yesterday - I hadn't seen one before.

[Bad Raven]

Not to my knowledge, at the time the Futaba 6EX was the std fare, not that long out of transition between 35MHz and 2.4GHz. I have two 2.4 FASST and "around" 6x 35's.

I suppose the nearest was the T8FG and FHSS operating system, but from memory that came AFTER the T9D.

The X9D broke new ground with its plethora of pots, sliders, switches (esp the number of three way). Obviously the open source operating system OpenTX was a completely new venture, one that a lot at my club sneered at. 

They're not now!!

Back to the buddy system, Painless360 has just published this: https://youtu.be/5KW_8HFxW4Q
It seems to suggest you can use a multimode module in an OpenTX radio that is bound to the student radio. Then the master (has the multimode in) passes the signal to the aircraft in buddy mode.

Seems like all badger1 might need to do is get a multimode module and update OpenTX?
Might be worth having a look?

[badger1]

thanks ched, interesting idea.  however, since neither my X9D or my friend's X9D+ has onboard wireless we'd need two MP modules, so I think we might just try a 3m cable first.

Neither tx needs the onboard wireless.

Basically the multi module has a normal receiver mode. So the trainer tx binds to the multi module in your radio and then the multi module passes signals to the internal tx of your transmitter. As far as the trainers tx is concerned it thinks it's just connected to a bog standard rx. Yor radio using a newish version of OpenTX takes the received multi mod signals and, depending on switch position, passes them to the internal tx.

So all you need is a multimode module and a newer version of OpenTX in your tx and away you go.....

I'm thinking it's maybe not common knowledge you can also do this with a cheap SBUS receiver like an XM+. That's more economic than the multi-protocol module if you otherwise would not use it.

oops - I should have watched that properly - sorry ched   I watched the first bit & wondered what frequency radio it was using to talk - I assumed it was using whatever the onboard wireless buddy system the QX7S uses (although I notice now his Slave Tx is a regular, non-'S', QX7).  it didn't occur to me that it used standard 2.4GHz & that the MP module would have a built in Rx.

I will watch it again properly & pay attention this time!

very neat.  the stuff you can do with OpenTX never ceases to amaze me.
