New WLToys Protocol V977

The code for KN protocol is accepted in the main Deviation repository. It was a true collaborative work, I just implemented it, but many people participated. Thanks to Ansheng I had early SPI traces which allowed me to resolve ambiguities in the documents. The documents were published in Chinese by KN itself, and generously translated by dc59. KN published them because of persuasion from James Chen of HiSky. I was able to verify how it all works together and tune it thanks to generous donation of V977 from Banggood facilitated by RCGroups' FyreSG and Banggood's Adam. Thanks for the first positive report when I still did not get my model to test, and for troubleshooting to Babay. And thanks to all brave people who tested the code blindly on their own helicopters.

Hi victzh,

You are the key man makes this protocol works!
Thanks.

Thank you for the very good work, wanna try on my new devo10 2km range, but what module should i install, i found in the forum the NRF24L01+ but is there not 2 different models ? where can i find the good one ?

This one is ok ?

or this one ?

Thanks

The second one does not have Power Amplifier, so no. The first one is very close to what I have. I removed the SMA connector and soldered an antenna directly to the board. 2km is probably not realistic with any of this.

you should take ths one :

the PA is +20dBm instead of +17dBm for your first link. The maximum distance is around 700m@1mbit/s in a really ideal scenario... 300m in practice is more reasonable.

You 2km advertising is for a specific walkera RX associated with the QR350 pro

Thank you SeByDocKy, and congratulations victzh and the team for this great work again.

I own a Devo10 and I bought this module on Banggood which works very well :

With respect to the first two links, it has a PA and an antenna which can be ept inside the Tx. Which respect to the previous link, it has an antenna which is useful if you don't want to solder one on it I think.


By the way , I'm happy that we may be able in a close future to pilot a V977 BNF thanks to the fabulous work of all of you guys

The nightly is already out for the V977 so basically we can already fly a BNF

Share the test modle file for V977:





DEVO 8/10:
Gear SW: 3G mode(0) / 6G mode(1)
AILE DR SW: DR High(0) / DR Low(1)
FMode SW: Normal(0) / Idle(1) / Normal(2)
RUDD DR SW: Normal(0) / HOLD(1)

DEVO 7E:
HOLD 0 : Normal
HOLD 1 : HOLD
FMODE 0 : Normal
FMODE 1 : Idle
Channel 5 DR default = DR High(Stable mode)
Channel 8 3/6G default = 3G mode

Is it ok for me to post ini file here or I should move it to Model Configs
thread?

Thank you ben1977 for the link, i'll buy this one

Someone should add this bird in the Database

Yes please post your ini, thanks.

Hi, is it worth buying the Rtf version or the BNF is ok with the actual .ini file ? Thank you for your feedback

Hi, I'm brand new so pardon me if this question has been answered already. Will this control the v930? If so, what do I need to do? Thanks.

Good morning everyone, does anyone know if this module is compatible? or have to use those mentioned by you?

Thank you very much.

No both are radio adapters that work off a tx ppm signal and both are for Hisky protocol only.

Many thanks joeclone, then the only way is to bind using the correct internal card?

Thanks.

Or combo with antenna:

Do not turn on the module without antenna connected - you can burn it.

Thank you, but still did not understand why the module below does not work?

The protocol is not the same as the v922?

And does anyone know about the 4 ch fixed pitch v930? I'd like to use my Devo 10 instead of the toy TX that comes with it.

Yes, the protocol of V977 is totalli different from V922. V922 is HiSky rebadged and use their protocol, V977 is produced by KN and use their own protocol.

I believe that V930 and V977 use the same protocol.
