I have plugged NRF24l01 exactly as writen. Power to 3.3V on power have 100uF and 100nF capacitor. But I have unreasonable incoming digits

Seems like bad wiring. Triple check it.

Plus the sketch you are using is extremely old. Use the ones built into the
library instead.

Try 1000uF capacitor soldered (!) directly to the VCC and GND pins of the
nRF24L01+.

Make sure the distance of the Arduinos is at least 1m but not much more.

Make sure you have correctly defined the CS and CSN pins (see PingPair
example to see how it's defined).

Make sure you have correctly changed the radio number.

Make sure your wires are not too long 15cm max, the shorter the better plus
make sure it's thick enough so no ribbon cable.

ok, I have checked wiring several times,
NRF Arduino
GND GND
VCC VCC3.3+
CE Set to 9
CSN Set to 10
SCK 13
MOSI 11
MISO 12

I use example what is coming with library. (Getting Started) example in TMRh20 library
CS an CSN pins is set as it need to be, I have changed to diferent pins too.
I have trying several distances from 1m to 10m
Radio number on one arduino is 0 and on second arduino I have 1
wires I have 4cm short.

Stil no luck with comunication. I have changed NRF boards to with new one, no result.

I have measure, board have exactly 3.3052V
Capacitor is added, but result is the same.
I also have nRF24L01+PA+LNA and with this board result is the same.
I have desperate, what is wrong?

HI,

HAVING SAME PROBLEM...

This is my 3rd day trying to send "hello world" using this tutorial https://www.youtube.com/watch?v=7rcVeFFHcFM&t=353s

I've tripled check all connections ,,, added 1000uf cap... stable 3.3 v using osciloscope ... reinstalled IDE and RF24 lib...

nothing ... doesn't work

i'm just going crazy... such simple should be but ......

@Avamander

Stable 3.3V but do you actually have communication? Does printDetails() print the right details? Are you actually using the latest stable IDE and library on a clean install? There are quite a few variables here and you mess one up and you won't get it working.

Allecsxx commented Dec 9, 2017

DOWNLOADED 1.8.5 IDE and installed after using ctrl panel to uninstall old one, deleted all old libraries files etc
Installed RF24 tmrh via Arduino.

arduino UNO connections :

SCK =13
MISO =12
MOSI=11
CE = 7
CSN= 8

MEGA 2560
CE =7
CSN =8
MISO=50
MOSI=51
SCK=52
ALSO added pinmode 53 output in void setup

Im using 3.3 v source from https://www.eetimes.com/document.asp?doc_id=1298322

ADDED 1000uf cap aswell

soldered connections between nrf24 and arduinos...

I have 4 days now trying to send hello world ... i 'm going super crazy

I dont remember exactly, but try to CHANGE radio Number at the begining of the sketch. Uno could be 0, and MEGA could be 1. Check that way

BOTH NRF24 can't be faulty because i have a RC remote controll modified by somebody to drive the DRONE via rf24 module and both of them work ...

Allecsxx commented Dec 9, 2017

USING getting started..

SERIAL monitor for UNO responds to T and R key but mega doesn't .... on mega it is stuck on RF24/examples/GettingStarted
*** PRESS 'T' to begin transmitting to the other node
if I desolder CSN or CE it responds to buttons...
also there is no doubt that CE and CSN are not connected correctly.

@Allecsxx If it were a bad library it wouldn't work for anyone, "on mega it is stuck on RF24/examples/GettingStarted" sounds like your connection is messed up. You also haven't mentioned what's the output of printDetails() what is rather crucial to debugging what's wrong with your setup. Also please don't spam the issue tracker, you could have fit all your tests/issue into one comment.

The modules will never work without CE and CSN connection. It's quite likely you've forgotten to update the pin definitions in the sketch following that YT tutorial (it isn't using the default pins) instead of the default pins in the documentation.

Also a good point will be some info to help people identify cheap clone nrfs...

The counterfeits tag has plenty of issues about it and they contain information about the various problems one might encounter and how to recognize them. It's borderline impossible to detect actually bad clones visually unless you have those chip-under-epoxy-blob ones.

@Allecsxx

Well ... If my SMonitor was at least printing details probably i was wasting less time. I don't understand why on Win8 Read Only print.f file will not be read by #include... I tried with older Arduino IDE... 1.6 and it wasn't working either. After reinstalled again last 1.8.5 still no luck... I don't know how it came in my head to untick Read Only but was a big big step forward.

Sorry I do not have arduino anymore. Can't help you with print output.
But here is the whole code.
The thing is, it still doesn't work even after solving this problem. It sends properly but RF24 does not receive data properly(always receive 0). I believe it's due to hardware problem(noise on power).

Hi,

There are a couple of months since i ve moved to e32 ttl but u still remember a but,

Autoack false sorted out the problem for a day or two.

The whole problem was 3.3v. I had a shit 12v psu powering up arduino and from there a 3.3 power module to nrf. The whole issue was the shit noisy 12v psu which was so bad , more than what arduino 5v and thereafter 3.3v power module could handle with their capacitors filters Tried with capacitors on NRF module etc, didn't worked at all. So i replaced the 12v psu with a better one and cleared all problems. It worked with autoack true after.

@Allecsxx

Also i tried to understand the print details, i remember Avamander gave me a link, or i google it , looked into for an hour and after that i could easily spot what was going wrong. I did had same thing... transmitter sending and printing good details but receiver not doing anything. All was about shit 3.3v. On mega there are some guys saying that pin 53 or 51 or 52(don t remember) needs to be output or something like that... but i can say that is not the problem. After having proper 3.3v i tested with initial code getting started and all worked perfect.

@Allecsxx

My advice will be to change whatever Psu you have , a desk regulated psu will make your modules work

@Allecsxx

I have this psu which sorted out the problem. Any psu like this will make your nrf modules work properly

If it works with a desk psu on the prototyping stage and not working with your finished project psus than you have to look further and filter the noise.

dunelo commented Jun 27, 2018

I also tried that! but i just used an old power adapter connected to a 3.3 volts regulator directly to the module. So i used 2 adapters for my two nrf modules and it worked so good, so consistent! BUT A FEW DAYS AFTER (maybe a week) i dont know why until now its not working!!!! OMG!!!! And now i don't know what the problem is. I'm so desperate haha. 'coz my head is so aching as hell. Also before i tried that power supply solution, (I'll just gonna share this) my project wont connect at first after 3 tries and then it will work so i thought its just the nature of the nrf to not connect at first and then after some time it won't work so i tried the power supply solution. HAHA

So right now, i'm thinking of what was the problem.
Is it that the power adapter has too much noise?
or
my arduino needs more power like what you did.

HELP HAHAHA THANK YOUUUU

Usb from laptop will not supply enough current for arduino + nrf. Trust me , i tried with that aswell months ago and it didn't wanna work. I ve been agains all advices because i was looking into datasheets and believe the values of current draw of nrf and current supply of usb. Don t believe , lisen what i m saying... i spent days and days because of that. Get a proper psu and you will save time(days ) of fault finding.

Grrrrrrrrr. HAHAHAH so what i need to do is to supply both my arduino and nrf (the power supply is connected to the arduino and also connected to my 3.3 regulator for my nrf)? With that proper psu..

F.ck me.. i still remember the days lost (8 in the morning till 23 pm) for a couple of days trying to figure out what was the problem. I ve lost weight aswell in that time as i was so nervous that i didn't wanna have any food at all. :)) i was looking to the small nrf module and swearing it on all possible ways. I ve done very complicated projects in the past and i couldn't believe i m gonna get defeated by a small module ;:)))

Power up arduinos with desk psu, connect vcc gnd from each arduino to 3.3 v nrf modules.

The good thing with desk psu is that you will see the draw current by your whole project and you will be able to create a psu after that will suit your project.

The printDetails() output means the module isn't connected. Next time open a new issue so each case can be individually handled.

Ok... Now it's quite... Thanks for help. Definitely there is a issue with the library. If at least somebody was ibterested to debug i would be keeping it... But as nobody is interested i will move on

Hey could you please share, what was the problem exactly and what was the solution that worked for you? & what library did you use? I am trying to make it work for days, no help... Please kindly help me!!!!

A random issue is not the place for asking help with some different problem.
