V202 protocol

The nrf24l01 certainly seems to have some kind of power problem. I have one with the PNA but its range is pitiful. Something bad is going on with it.

The range for my nrf24l01 is pretty good. I can fly my quads till I can no longer visualise its orientation, probably over 100m. However, I do encounter a bug which sometimes corrupt the Devo screen. I thought that had been reported long time ago and was fixed.

Same here, I have nrf24l01PA module built-in into my Devo 7e, no problems with drop-outs at all. All gone, after Banggood sent me a new receiver board. No idea what they changed, but it simply works now. Note, that there had been a new transmitter sent by Banggood, before the new receiver. However, the new transmitter was irrelevant to the droup-out issue.

Massiveoverkill got a similar unit as mine and has the same range. Only 50 or 60 feet. He's got a devo 7e and I have a devo 10. He can fly his v262 out of sight. You'd swear it was gone forever, then here it comes flying right back. EDIT: (Using his stock tx)



My v202 and v252 both drop mere feet away, same distance for massiveoverkill as well with his quads.

No problem of range with the V2x2 especially with devo TX

i own a wltoys v212 and a devo 7e tx with deviation.

im looking for model config for my v212, or maybe somebody can help me understand the hole complex adjustement so i can do it my self, i would like my quad to be able to have nice smooth flight on fmod switch 0 and a full agility mode on fmod 1 or something like that so i can do flip and even loop if possible, i already had my devo 7e with deviation and took the original remote nrf module, binding is ok, but have to re do it everytime, i had a few flight but no info on how to create my own config, can anybody help me out ??

WRT bad range - it seems there was a defective batch of V202 (not sure about V252) receiver boards. RF is not trivial to tune and very easy to ruin, you have small deviation in values of one of impedance match network elements (these small flees near the antenna) and your antenna is out of tune and range drops by factor of tens, maybe hundreds.

For what i think, sounds like the v212 protocole is not as ajustable as want it to be, rudder is too slow and the quad is not very agile, i will be replacing the board as BG send me anoyher since the bind leds is not working and the copter is wabling, if it does not work properly i will try a board from a BLADE 180QX and see what i can get from it.

I took the module of the original remote and install it in my devo 7e, and the range is incredible, out of sight as it is. the only thing is i cant seem to know how to change the value of fmod to change the 6 axis stabilisation, sounds like its always on 100%, i can do flip at 100%, but the loop is harder, and the rudder is always too slow, i hope the new board will be ok if its the problem.

do you think the 180qx board wuold be more effective for fine tuning ?

i would like it to be as agile as the traxxas alias, is it possible ?

Quick question, do you have to manually rebind every time with this protocol.

I am using 4.0.1 on a Devo 8S with nRF24L01 module and external antenna.
On mine I have to rebind every time.

Thanks.

Anybody else using this protocol?? Do you have to rebind every time you start up the Heli?

If so it would be nice if we could put the rebind on a switch so that we would not have to go into the menu to start a rebind.

Thanks

Bump....

Do you need to rebind the model each time with original controller? As far as I can recall - yes, the model just does not store bind information in it. The original controller starts in bind mode and changes into work mode after gesture - throttle up-down. What I can do is to add an option to the protocol so that it will start with bind mode.

Thanks for the reply.

I do not have to rebind each time with the original controller.

So if it is possible to add the option to start that would really be nice. I am using the latest nightly build.

Thanks again

What model specifically do you use? V202, V252, anything else?

I use the V222 Quad, that's all in the WL Toy's

I use Devo with Walkera's

I use DSMX with Blades.

Do you need a copy of my V222 Model.

Hmm, I suspect that you do rebind every time, it just happens automatically - you turn on the V222, then transmitter - it starts in bind mode, then you make a brief up-down movement with throttle stick and it's ready to fly. Actually, it just have bound. If you did NOT make this brief throttle move and it's ready anyways, it's surprizing for me.

What I can do is to replicate this behavior, just without throttle movement.

Only with using the original transmitter, With the 8s no stick movement ever binds it, I have to go into the model menu and hit the bind button.

Thanks

PS I know how to replicate the stick movement, but since it does not bind it on the 8S, I don't see how that will help.

Yes, I was talking about original TX, Deviation does not have any gestures implemented.

So can the gestures be implemented?

You don't need a gesture. You'll just turn on the TX, it will be in bind mode for several seconds, then you fly.
