Sky Viper journey transmitter

What type of transmitter Will work with the Journey electronics and what would I need to do?

dkemxr · February 2, 2019, 2:16pm

It’s not a $64 question it’s a $35 question Assuming you already have a Transmitter for the module to plug into that is!

1942 · February 2, 2019, 7:14pm

Don’t have the transmitter for it nor not sure what I need to do

1942 · February 2, 2019, 7:16pm

Or in that case What I need

After establishing if the Journey in fact is on DSM2 protocol like 2450GPS any radio with a module bay should work with the Orangerx module.

Paging Dr MattM is the Journey on DSM2 ……

Ok. Here is my ignorance … What is a module bay? I’ve not been in this for long except for older R/C cars Hell, I still have a Cox P49 motor and use to be use to strings. Lol. I’m semi-retired and really want to get into this … I’ve messed with electronics most my life but the majority was TV’s,vcr’s,stereos … Stuff you could see with the naked eye and 1958 Brunswick Pinsetter for15 years and AMF Pinsetters for about the same amount of time AMF had tubes and Brunswick had more relays then I could count … Thank you for any guidance or help that I get from you and anybody else !

I assumed you have a Journey and was looking for an alternative to the stock transmitter. Nothing wrong with the stock transmitter…

I see, you have a Journey and no Transmitter. Try eBay.You are going to spend quite a bit of money on a radio and module to get that $100 craft flying. Maybe sell it and buy a new Journey?

If you want a radio to grow into and use with the Journey a Taranis QX7 would be a good choice. Then you will have to spend another $35 for the module. Again, assuming DSM2 will work.

I just thought since I’d got all new in bags with some other parts that I would just build my own on a frame of my choosing… My granddaughters gave me a gift card to Hobby King for Xmas. I’ll just take a 20 minute road trip and see what they know

Is that a screengrab from “Bewitched”?? Elizabeth Montgomery and Barbara Eden from “I dream of Jeannie” were excellent guides for inspiration during my childhood

Journey uses open DSM2/DSMX protocols as well, yes. Early prototypes were controlled using an Orange Module on the Taranis.

Didn’t test it like that near release, though, but a few threads have shown people have their Sky Vipers hooked up that way.

Matt I just opened an issue = Cannot Bind after flashing new firmware (waf build)

Do you have a clue ?

Matt_M · February 5, 2019, 12:47am

Hi there.

Sorry, no clue there.

We haven’t tested with any of the latest firmware builds… only the official firmware for Sky Viper release.

Can you bind when the Official firmware is loaded back on the flight board (arducopter-2018-07-14.abin) ?

ppoirier · February 5, 2019, 1:09am

Yes, just tried, and it is binding within 5 seconds

Edit : Please note tht I did not needed to bind when loaded the original firmware back

Matt_M · February 5, 2019, 2:10am

Yep… sounds like a radio binding check isn’t in place.

Hopefully Tridge can make that fix down the line, due to your request.

Nice catch!

This was an issue I reported a while back in the master branch, but it got fixed. I’m going to try to hunt down where the details are at

EDIT: here it is.

ppoirier · February 12, 2019, 1:23pm

That was related to the 2450 ,note that what I reported above is an issue with the Journey skyviper-f412, and it is not binding at all.
Thanks anyway for the input

lordneeko · February 12, 2019, 1:27pm

right. but the reasons may be related. a change was made to some #define which the SV depended upon.

Matt_M · February 12, 2019, 9:15pm

Also something to check: The expected chipset. Look in the RADIO section of the parameters for BRD_RADIO_TYPE.

There are 3 types available here:

1 CYRF6936 is the selection for the V2450GPS
2 CC2500 is for the Journey
3 BK2425 is for the FURY and SCOUT

There’s a possibility that the Master got set to a different chipset selection on check-in, maybe? Check this param and if it’s not correct, change it. If it was off, it won’t connect to the corresponding flight board.

But CC250 is FRSKY ? Do we need to set a different radio protocol on line 66 ?

BTW did you had a chance to look at my blog Vision Positionning Experiments using SKYVIPER

webbbn · March 16, 2019, 2:39am

Has anyone actually used a standard Tx (Taranis, etc) with the Journey?

From what I’m reading here, the Journey uses DSM protocol over a CC2500 radio link. I assume this combination could be added to OpenTx, but AFIK, the Frsky protocol is usually used with the CC2500 radio.

Assuming my assumptions are correct, should it be possible to fly using Mavlink over WiFi?
