@Yveaux
Thanks a lot for your feedback.

I used very basic W5100 HW as on below link link text.

Why MySensor forum do mention "The W5100 ethernet module has problems sharing SPI with radio" recommending to use soft SPI with such unit without SD card ?

I must admit, I implemented sketch and wiring as recommended by MySensor forum with no brainer.

Lots of post like here link text seems also to confirm issues in the way W5100 handles SPI bus, a reel night mare, I haven't found any succesfull experience in forum yet.

Should you have further information or maybe working sketch to share, I would very much appreciate.

I have no logic analyzer so would prefer to avoid entering in long debug session but if you confirm W5100 and NRF on same SPI bus should work, i'll make a trial and rewire mine.

@benbidouille I've run multiple gateways using W5100 on hw spi with atmega328 and never had any issues apart from that SD card select line.
I'm not sure why the docs mention there would be a sharing issue.

Thanks so much for confirmation,
Seems a large community of people faced the issue here back in 2014 link text , and the recomendation comes from this past experience.

My undertanding is nobody re-challenged the recomendation and possibly are we the only one interested in getting IRQ with NRFDoctor.

So is a good news you confirm it works.
Can I assume you use same W5100 HW shield as mine and that you have for HW connections:

• W5100 (CS/MOSI/MISO/CLK) wired respectively on HW SPI (10,11,12,13)
• NRF24 also on HW SPI for (MOSI/MISO/CLK) only and differentiated CS/CE/IRQ on for instance respectively 6/5/2

Regards and thanks for these precious informations that will help me saving time.

Very interesting. I just (few weeks ago) built an Ethernet gateway recently and at the time followed the recommendation for soft SPI. Then more recently I read about hardware SPI being required for MY_RX_MESSAGE_BUFFER_FEATURE which of course would be a valuable feature on a gateway.

@benbidouille,

Did you ever investigate further? Even if not, I will probably do so on my own, sooner or later, as I have a few of the various W5500 cheap modules here...

Hya,

correct me if i'm wrong.

To make use of this, two units must be built. One for node and other for gateway.

Is this undestanding correct? If not, how to use nRF24DoctorGateway and nRF24DoctorNode?

Thx in advance.

Yes it is

I need some help.
I just built an NRF24Doctor following the instruction in the post and on Github.

• When no NRF24 module is connected, the device starts properly, displays the menu on the LCD, and when I try to select a menu item, it (correctly) displays "Radio init error. Replace radio".

• When an NRF24 mode is connected (I tried several), the LCD is blank, the serial monitor shows "Channel:90 PaLevel:HIGH PaLevelGw:LOW DataRate:250KBPS Dest:0 Payload:2 Rate:10" in an endless loop.

• when I run the older "nRf24L01+ connection quality meter" software, it starts ok and the LCD shows FAIL 0% and MISS 0% as expected.

Any ideas for what might cause this problem? Almost looks like it resets in a loop, maybe because the watchdog triggers? or stack corruption?

Hello all,

First things first - this is a great device, kudos to everybody involved!

I built a buggy nrf24Doctor - it wasn't measuring the current consumption at all ("xxx Err" message). Trying to fix it led me to refactor the - splitting it into smaller "components" and adapting the project structure to VSCode/platform-io (ArduinoIDE is not my cup of tea).

If someone is interested, the code can be found at github.

Regards,
L.

The output of the display could also be sent over serial, but the whole idea is you can walk around with the doctor and improve your results as you go.

Sorry to necro this old post :(
I have just uploaded @yveaux's version of nRF24 doctor to a Nano.

I got all the right libraries installed into IDE (especially LCDMenuLib2.h version 1.2.7, i also tried several other versions close to 1.2.7 just to be sure).
But when compiling i get the following errors :

/tmp/ccMpih6l.ltrans0.ltrans.o: In function `global constructors keyed to 65535_0_nRF24QualityMeter03.ino.cpp.o.3416':

collect2: error: ld returned 1 exit status

Erreur de compilation pour la carte Arduino Nano

That is a bit above my knowledge. Could someone please point me into the right direction? Could it be just a case of "wrong naming" of variables ?

[ben999]

I might be able to answer that myself !

Looks like i have forgotten to "combine" a .ino file (CharLcdMenu.ino) with the main one (nRF24DoctorNode.ino), which seems to be a bit like a sub-program.

edit: that's it. Just had to create a second TAB with that sub-program, compile and success.

Please forgive my lack of vocabulary and knowldge, i am a "copy-paste" engineer :D

It's great when a project can be brought to life after 8 years!

[ben999]

@OldSurferDude as long as we’re using nRFs this project is still relevant :D

Great little tool to check for efficiency of modules

I can even « aim » a pcb antenna to get the best result !
