Devo 12s 3in1 / 4in1 RF module neat installation.

The best approach to adding modules is to take out the PCB and solder pins through the holes. Not sure if there's a hole for B7 on the 10, and since this takes a lot of extra work, it's not clear it's worth it for the 4-in-1. I put them in my old one with a multimodule and it was well worth the effort. I didn't bother on the new one with the 4-in-1.

Thanks for the responses!

Hi, am new here and want to introduce myself shortly.
My name is Lothar am 65 years old and since 45 years model builders and pilots.

Now to my question:
I've installed the 4 in 1 module by Banggood in my Devo12.
All the very latest firmware.
I could bind the following recipients so far: FrSky X 8, D8RII, Orange RX 6, 8 and 12 channel, Devo R602.
Today I wanted to bind a FrSky V8FR, no chance.
The X 8 and the D8RII I need in the frequency fine tuning on minus 40.
In the V8 I have no possibility to fine-tune, why log???

Sorry for mi bad English, that is the translator

Greeting

If this receiver does not bind with V8 you may get stuck. The V8FR_II receivers have a jumper to bind with D8 ( Deviation call this Frsky).
At this point you have the frequence fine tune available.

Hello aMax
the old V8FR can not bind.
also do not bind the V8FRII in the V mod
the V8FRII in D MOD can commit
Why is there no fine tuning in the V mod

1. At the time, when this was developed, none had problems with unprecise oscillators the Chinese use nowadays.
2. This protocol is rarely in use and the second edition of these V receivers can use D8.
Maybe this option will be put even into this protocol, wait for a developer answer.

Did you get your lifted trace problem resolved? I did the EXACT same thing on my Devo10, I tried a few things, and finally got to to a resolution that worked. If you still need some help or direction, let me know and I'll share what I tried and what worked.

Hello StevePropHead
Please, please tell me how you made it that the V-protocol binds.
I have 5 V8FR receiver which I would like to use.

Lothar

The VF8R-II can be used in either D-mode or V-mode. D-mode in Deviation is just FrSky. You need to connect the channel 1 and channel 2 signal pins when binding. Powering it on like that will put it in bind mode, no need to hit the F/S button.

The original VF8R does not support D-mode, and has to bind in V-mode. That is the FrSky-V8 protocol in deviation. Power the Rx up while holding down the F/S button to get bind mode.

Now hit the Bind/Reinit (could have either label) button in the model setup entry with the correct protocol. Since this is a CC2500 protocol, you may need to adjust the fine tuning under protocol options to get it to bind. See the wiki entry for instructions on how to do that.

Hello mwm

Everything you say is correct.!
I can link X with fin minus 40
I can bind D with fin minus 40

In the V log there in the transmitter menu of no possibility for fin do
I can not bind the V8FR from the old generation without frequency shift
Why no Fintuning in the V log

You didn't say what version you were using, but I suspect it's 5.0. The CC2500 tuning is a relatively new issue, post-dating the D & V FrSky protocols, and I don't know that anyone has made an effort to update all the CC2500 protocols to support it.

If you really need it, try the "5.0 with new protocols" build. The latest sources have fine tuning in the FrSky V protocol, so that build may include it.

Hello mwm

Thank you for your answer and that you assume you my problem.
Yes, I have the 5.0 on it. Last night I made the new nightly build version 2017 03 27 played on. No fine tuning in FrSky V.
I think there is currently no way the receiver to multi module to bind.
My best thanks that you tried to help me.

Hi, I remember that some time ago victzh mentioned a modified 4in1 module he had been working on that would enable installing the module in 7E without soldering to the CPU. Does anybody know if there is any news on this? Personally I would prefer to avoid the CPU soldering job but if that module won't be available I think I might give it a go.

Do you mind sharing the link to the Taobao manufacturer that sells the latest modules with fixed issues? Do you know if the current 4in1 modules have the issues fixed similarly to the 3in1 module you purchased? Also, is this module from Banggood you linked to earlier: www.banggood.com/CC2500-NRF24L01-A7105-C...itter-p-1096707.html exactly the same as the one sold on Taobao or do you think it's better to buy directly from the manufacturer to make sure to get the latest version?

Many thanks.

#if	0
static const char * const frsky_opts[] = {
  _tr_noop("Freq-Fine"),  "-127", "127", NULL,
  _tr_noop("Freq-Course"),  "-127", "127", NULL,
  NULL
};
#endif

So, I think it has not fine tuning.

Hello vlad_vy
Where see i this fin in my firmware

@czajunia, I sent design files for my module to the guy, who produces these 4-in-1 modules. The code support is there, in nightly builds. The guy is still processing the files, and should send me a test version, but it did not happen yet.

That's fantastic news. Many thanks for the update. And of course thank you for making the new module in the first place.

From your past experience do you know roughly how long it takes him to produce a board and start selling it once the test version is approved by you? I'm in no rush as my 3 separate modules work just fine but every now and then a Frsky protocol would come in handy. Cheers.

I passed the design Mar 9, 2017. He's now probably quite busy, our modules is not his only product. So I don't expect anything earlier than end of April. He's gonna use GigaDevices SPI memory (it adds normal amount of storage to Devo F series and Radiolink AT9) - I still need to cover this in the code. I'll use datasheet, but you never know until you tried.

Last time he implemented our small modifications on the 4-in-1 module pretty fast, but that was minor. And Devo adapter currently on Banggood is his own development. So actually it's hard to tell

I believe the Chinese manufacturers could be even more succesfull, if they would be bit more interactive with their community of users.
It seems they indeed read learn and copy from all conversations on the web, but not really inform, share or ask for any feedback help for their new products.
A close relation with customers could make a win win, better sales success and for us better products we like.

So please post some progress and updates on the modules...!


Oh btw one more wish;
If for the new modules the, each of the RF chips Xtal loading capacitors could selected with care to be spot on, so freq offset should be close to zero, would also be an good improvement for all of us.
