The 3-in-1 / 4-in-1 are using 40 or 60 ppm crystals because that's what is stated in the nrf24l01 datasheet ( www.deviationtx.com/forum/protocol-devel...-q303?start=40#55616 ), but that's not accurate enough. Some units have better tolerance, that's why not everyone has the problem.
A possible fix is to replace the loading capacitors that are located around the nrf24l01 crystal to trim it (15pF, 0402 package):

Okay, thanks for the "lighting". :) I think I have understood. So it is well possible that with another E010 my 3in1 works reliably. Equally it is possible that the 4in1 with my E010 likewise not works, because the tolerance of the components is too large, right?

I think it wouldn't work better with another E010, the issue is on the TX side.

... also, I'd like to state the manufacturer is not at fault basically, because 40ppm is fine for the nrf24l01+, but here we're communicating with a xn297L which requires 20ppm accuracy for 250kbps.
I think ajtank reported the problem and it should be fixed in a future revision, don't ask me when, I've no idea.

Many Thanks. Since I'm the install the 3in1 / 4in1 modules in my Devo7e just trust, that is probably my limit. A replacement of SMD components is unfortunately not my case.
So I would like to wish you luck with the ordered 4in1 module and the lottery game has an end.

Instead of fiddling with loading capacitors, maybe would be possible to replace the xtal with hot air and some kapton around? But for the expierenced modder............

I used e010 with multiprotocol ,I had the same problem at the beginning, delayed controls and problems with binding.
I solved the problem, like this .
I removed the e010 canopy and took the antenna out in almost vertical position(it was horizontal laying on the board).Additionally I found that the multiprotocol antenna was faulty and i changed it.
The result .... no more problems.Before doing something drastically try these small tweaks.

midelic:
It's incredible! I could solve with your suggestion the problem with my E010. The control works at least 10mW and within a room. Certainly, this measure will not suffice to fly through several rooms, but it bridges the wait time until the 4in1 module arrives. In advance, I can already mount the necessary 2.4GHz antenna.
Thanks again.

Hi dc59, I bought my 3in1 in July 2016 and it is installed in my Devo 7e. I have a second Devo 7e with this standalone NRF24l01 installed and it flies all my quads including several Eachine e010 perfectly.

Basically the NRF24l01 chip in all the 3in1 is either a clone or has some sort of defect in it. I have the same problems and even other toy quads will fly funny with it.

So, to everyone out there, DO NOT BUY the 3in1!


Hi jayodas,
When did you get your 3in1 ? I don't have this problem with both my 4in1 and 3in1, could it be possible that's caused by some batch of nRF24L01 chip?

My 4in1 works perfect on 10mW. No range issues. And i even have antenna on quad horizontal.

Okay, I tried again today at 10mW. The antenna of the E010 was bent in the delivery condition in the form of a "V" (I noticed only now, when I removed the cover). :dry: I just bent this straight. The antennas of original RF antenna and antenna of the 3in1 module I had previously both lie in the housing of the Devo horizontal. Now only the original antenna is in the housing. The antenna of the 3in1 hangs for the time from the Devo. :silly:
This means that the connection is also available in all rooms in my apartment. However, no AIO cam has yet been mounted on the E010.
I will use a 5dBi WLAN Omni antenna and hope that then no problems occur (even with full FPV expansion) :woohoo:

Best regards

I finally got around to ordering the 4-in-1 module from BG and received it the other day. I installed it this morning and had to re-bind all my DSMX-based quads. I'm guessing this is a side effect of changing out the module somehow so that's probably OK. What concerns me is that all my LemonRx satellite's LED indicators are now flickering/strobing:



I didn't pay much attention before, but I'm pretty sure they used to stay solidly lit, or at least flash faster than I could detect. I used "set spektrum_sat_bind = 9" in Betaflight/Raceflight CLI and performed the rest of the binding procedure as usual. The flicker makes me wonder if I'm having continuous micro/milli-second signal dropouts, which will undoubtedly cause lots of problems. I did a range test in my neighborhood and didn't get as far as I thought I should, but I've never done the test this way before so I'm not sure how it compares to the original module.

Is there something wrong, or is this normal?

There is something wrong, but quickly fixable, if it is what happened on mine (I have an OrangeRX110 sat and redcon sat). The light should be solid. I don't think this is an issue with the 4-in-1, because I repeated the issue on my Devo 6s with a multimodule board as well as a 4-in-1 equipped 12e.

For both I needed to clear the fixed ID and bind, then repeat the cycle to set a fixed ID.

Power on the TX, clear your fixed ID, then power on the quad and use the CLI command as you did before (probably doesn't matter much, I have been using "set spektrum_sat_bind = 7"). It will reboot and reconnect, so disconnect and power everything down. Power on the TX and then the quad and the sat blinks fast, hit bind on the Devo. After a few seconds the light should go solid. Power off the quad, give it a few seconds, then power up. It should bind with a solid light.

Power everything down, then bring up the TX and set your fixed ID. Then repeat the process starting with the CLI command.

Ahhh, thank you so much, that got it. Not sure what that was all about, but this seemed to fix it. Strangely, I had to pick an entirely new fixed ID or the rapid flashing would come back even after clearing it and getting it to bind with a solid LED. Any idea what the flashing indicates? I went flying earlier today before applying the fix and didn't notice any range issues at all.

It should be located here for 3-in-1:

Jayodas: Already tried this? Before you carry out complex work, you should make this attempt absolutely.
With me it worked (almost like a miracle) ...

Hi,
just finished 4in1 for Devo 7e !
I have a big problem with PA, it doesn't work ! Only for DEVO/DSMX (CYRF6936) protocols I have good range (same as stock WK-DEVO-S-MOD).
I have solder the wires using this set up :
www.deviationtx.com/media/kunena/attachm.../1511/4in1wiring.jpg
This is my wiring :
drive.google.com/open?id=0B2ETpS9VxovVYWJPTEtwQVRVenc

Everything work fine , I can bind Flysky, Frsky, DSMX, (don't have others to bind) I can see all protocols in deviationtx 5.0 (no asterisk * ), I have change the Hardware.ini with every possible combination (off course I delete ; )

I am using this now :
; enable-cyrf6936 = B12
; has_pa-cyrf6936 = 1
enable-a7105 = A13
has_pa-a7105 = 1
enable-cc2500 = A14
has_pa-cc2500 = 1
enable-nrf24l01 = A15
has_pa-nrf24l01 = 1
; enable-multimod = A13

I have install again and again deviationtx 4.0.1 - 5.0 - nightly builds
Check triple check wires - solder - connections
I have 6.19V to 4in1 module using 2s Li-Fe 6.6V
Losing signal at 4-5 meters in 150mW (choosing less mW meters decrease)
I have 2 4in1 modules ! Same results ! I bought them from Banggood www.banggood.com/CC2500-NRF24L01-A7105-C...07.html?rmmds=search
I have external antenna (antenna mod)
I have 3x2 switch mod

Does this still require testing? I have a Devo 7E with an updated CYRF module plus A7105 and nRF24L01 modules. I am happy to test it but I am not sure if first of all that's still necessary and also which nightly I should flash.
