Radio protocol question - Stock OpenTX

[zflyer]

In Companion9x (1.48) I see several options for the radio protocol for a model in the Stock OpenTx environment. One of which is the FrSkY DJT which I am trying to select. Here is my question : I select this option in Companion9X, write the EEPROM to the radio but on the radio display the protocol does not match this setting - it is PPMSim or something like this. How can I enable the FrSky DJT setting on the radio ?

Thanks.

There is no "DJT" option. The DJT is a generic PPM module, nothing special. It works with the default settings.

[zflyer]

OK thanks.

My actual challenge is to get my standalone XJT module to work with OpenTX on the 9X. So I was assuming I could select DJT as the XJT can probably emulate the DJT. Should I still go with PPM for the XJT then or is this the murky territory of PPX ?

[Kilrah]

With PPM the XJT will work just like a DJT indeed.

I have found an openTX firware issue

If you have the XJT and using stock firmware on the 9XR and you have it set to support D16 when all 16 channels will be output and if you use the sbus for ch 9-16 all is well

If you now flash the 9XR with opentx, when i see this

1 no option to chose D8 or D16 with XJT selected.

2 if you have it set for PXX or PPM16 with 16ch selected, when you can see alloutput on the monitoring screen, but a big but you can only use 12 channels.

The programing for the sbus is correct since it worked with stock 9XR feirware and also with Taranis radio

Somwhow you can only use channel 1-12

13-16 will not work, only if you flash it back to 9XR stock, we even reflashed the module's and receiver's with the XJT firmware on frSky web site no difference.

So OpenTX software peoplewhat do you need from me so we can have a fix.

I also like to see the option like you have on the 9XR with selecting XJT and D8/D16 or long range mode and receiver number.

Which module did you flash? With which firmware?

I did flash the 9XR using the companion software and i have selected this
Frsky, Heli, templates,DSM2,ppmca,ppmus,gbar,symlimits,potscroll,autosource,autoswitch,battgraph,sqt5font,pgbar

SVN = opentx-r2834
Variant = 215-32771

I have opened an issue ( #498 ) in the github issue list for openTX. Please note that openTX is moving from Googlecode to github. The issue list on Googlecode should no longer be used.

[backman8571]

Cool thanks

Just tried my Taranis using the XJT and 2 X8R receiver's and sbus model's

All 32 channels work fine no issue find so far

[backman8571]

I have one more thing we should ask for

When we run the companion and do test programing it would be cool to have a plane jet helicopter or quad so we can see any movement's.

Also when we program sound's or beeps, alarms why not play them on the PC also

This would be a game changer in my opinion

PXX is not implemented yet in openTx for 9x/9xr, so you can't have all 16 channels with an XJT. You can use PPM and have up to 12.

Oops, I thought PXX was available. I will close the issue ( if someone hasn't beaten me to it )

Volare necesse est, vivere non est necesse.

[MikeB]

Confusing, probably because PXX is in er9x.

Mike.

[backman8571]

And PXX is the open on the screen after you have flashed the radio

Per

[backman8571]

Here is a picture of PXX in the menu

If i use PXX or PPM16 will not make any diffrence

CH 13-16 is not being output at all

Per

[Kilrah]

Anything that is between brackets means that the relevant option is not selected in the currently flashed firmware, so it's not available.

So in away the old/new software that was delivered with the 9XR is better it does support 16ch it has option for XJT but no Telemetry.

So my question would be when will OpenTX have this upgrades??

Per

[dvogonen]

Depends on if and when someone is willing to take on the integration and testing needed.

At the moment none of the OpenTX developers have the necessary hardware combination (9xr+XJT+X8R+2sbus decoders).

[backman8571]

Can they not reuse some of the code from the 9XR since that has the code needed for support of XJT module

Per

[Daedalus66]

But what dvogonen says still applies.

[backman8571]

The 9XR and XJT and sBus module's has been out for 6-12 month now and no-one has it ???

Sounds to me they are not interested in the 9XR development , maybe focus on 9XR pro instead

[dvogonen]

That is probably true. HobbyKing made some very strange decisions designing and releasing the 9xr, which did not make it a favorite radio for the developers. There has been little interest in producing modification information etc for it.

The development of new features has lately been focused on the Taranis. The reason is that the electronics of the 9xr and 9x are quite old by now. The Taranis and the 9xr Pro have much more available resources and are likely to receive more functions going forward.

The developers do it for fun and for free, and thus:
- Aren't particularly fond of having to purchase every new thing that comes out with their own money as that quickly adds up. In some cases like with the Taranis the hardware was provided by the manufacturer, but in the case of the XJT the openTx developers didn't receive samples. Even if some code already exists porting it and making sure it works reliably is still some work, and when you don't have something to test it and have to rely on others' feedback it quickly takes a lot of time.
- Tend to spend most of their time on some combination of what interests them the most and what seems most users will benefit from. PXX support on stock has been in rather low demand until recently, and with limited staff there's tons of stuff already in progress that needs to be polished until work on that can start.

By the way, openTx being an open project anybody who thinks he can help and is interested in doing it is welcome to join the effort and contribute.

[backman8571]

If they find a way to combine the software i would love to help and test it
