V202 protocol

victzh,

I was wondering how come the 202 protocol only has 6ch support?

I was able to bind to the v222, which is the new protocol WLToys v959. The quad with support for camera and other accessories.

Looking at PB's FlySky support of the v9x9 quads, he said that the accessories are on channel 5,6,7.

I was able to enable channel 5 mapping on the v202 protocol to turn on and off the v222's LED. But I wasn't able to enable camera. And for some reason, Channel 6 didn't turn on video either.

Anyways, just curious on your thoughts for enabling the additional channels on the v202 protocol.

Thanks as always.

Channels 1-4 are real, earnest channels which are passed to the device as 8-bit values. Channels 5 and 6 are synthetic - 5 is LED channel with meaning of LED blink time, minimum - LED off and maximum - LED on. It is simulated on transmitter and passed as one flag bit of a special byte. Another bit of this byte is responsible for auto-flip enable, which I mapped to channel 6 for no better place. I can add channels for accessories, I just don't know where to map them, can only guess from where all other bits are. As I don't have V222 it's gonna be crapshoot, if you want to participate - you're welcome

Remind me, what Devo do you have?

That's right. I remember the trick WLToys does now from another thread on the er9x forum.

I am using a Devo 7e.

Is PB doing the same thing with the FlySky protocol for channels 5,6,7?

According to the manual:
WLToys V9x9: Enables enhanced protocol configuration for use with WLToys V959,
v969, etc models:
• Lights are controlled by Channel 5
• Video is controlled by Channel 6
• Camera is controlled by Channel 7

Could the source code give clue to how the special byte is mapped? Not sure if it's done the same way on the v2x2 protocol, but it may be a good clue?

I'll be happy to help test as always. Thanks Victzh.

I'll check but I don't think that V9x9 is somehow connected to V2x2 - they're developed by two different companies - FlySky and someone else - on contract with WLToys. This, by the way, was quoted as the reason they've changed protocol and radio.

On the other hand, there are limited number of bits in byte and we know functions of 4 of them - 2 used in binding packets, 1 for LED and 1 for auto-flip. So there are only 4 more and I can map them to channels 7-10 and you check what's happening if you turn this channels on and off.

If that's all the bits left. We can definitely do trial and error. Thanks.

Would I still need pin#2 connected? Couldn't I just bridge pins 2 & 3, and then connect to the VDD point on the Devo7e motherboard?

Hi Daroon

Could you please repost the schematic or pin connections to add the 24L01 to the Devo7e or 8s. It seems it is not available on the original link.

Hmmmm
I can see it just fine. It was posted a couple of pages back.

Server was down for a while. But as of yesterday, everything should be back to normal.

Please check again and let me know. THanks.

still fails ?

It's working for me. I think you're on an IP subnet that is banned. I don't know.

I attached it here for you to view though.





Cheers.

Thanks! This is what I get....

Just a quick thank you to everyone who's contributed to this!

I've just got my V202 flying with a Devo8 (using the module from the stock TX). As with the Hubsan-compatible module that I installed a while back, it was a surprisingly painless process and worked first time

(The inside of my Devo 8 is a bit scary looking now, though!...)

I installed the module from the 202 RTF TX into my 7E and having an issue. When setting up the model I can't change the TX power, it's stuck on default.(150mW)
I don't have this problem with the nRF24L10 module and was wondering if anyone else has noticed it. If I got a couple wires mixed up it wouldn't work at all right?

Did you enable the power amp in the tx.ini file?

I'm willing to help too! I'd love to get this working. I can fly the V222 so much smoother with the 7e, and I'd love to film and use the other accessories with that added level of control.

Do what you can man!

Jason, sorry - a bit pressing at work, and we're moving - too much stuff to do at a time. I will try to find some time for this, but can't promise soon. What do you have, Devo 7E, Devo 10, something else? I need to know to make custom build.

I have a 7E.

Whenever you have time man. I'm patient.

Thanks!!!

Daryoon, jason4207,

I added channels 7-10, mapping them to the rest of unknown flags. Attached is today's grab of PB's deviation repo with my patch, built for Devo7E
You can try, with some caveat:

1. I don't have Devo7E, so it can not work at all - I just built it for you.

2. I built this for Devo10 and tried it. My 2/3 of main screen stopped showing (menus work fine, you can operate all of them). The same problem is in tonight's deviation official nightly build, so probably it's OK. My V202 flies fine.

The mapping is as follows - any channel value <=0 - flag is reset, >0 - set.
Try for channels 7 to 10, report your impressions.

Have a good working DFU nearby (not tonight's), just in case.

Enjoy!

Looks like the new flexible GUI has been implemented. Not sure if it's completed yet.
But you can go into your Model Menu's Main page config to set what each box does.

But like victzh said, despite the home screen looking sparse, the rest of the menu functions like before.

I am walking user:Heli Pad through to test out the new additional channel.

As usual, Thank You for your work on this.

So far, Heli Pad reports that Ch 6,7,9,10 all trigger lights.

Ch 8 successfully trigger the video mode and captured video.

Wait, he reports some photos were taken as well. Not sure how yet because the camera module LED light did not blink.
