<![CDATA[Radio setup give: "check wires"]]>I'm pretty tired on this now, I have spent 2 nights and half this day on this problem. I think I have read all threads on this forum and tested every tip but still only get "check wires" when i fire upp my sensor. I have no "reference" working copy of a sensor so I can't verify that my Nano and radio is ok but since I have tested 2 nano and 3 radios it should be ok.

Is there any other way to test the hardware? Or is there any tip how to proceed? If there is any mySensor user in Sweden then I can send a radio to you and you can verify that it is ok?

I'm out of ideas now.

I cant get my sensor to work. After reset I only get the message "check wires" on the serial monitor. And yes I have checked the radio Connection many times, I have attached an image with my wireing maybe someone with "new fresh" eyes can see anything. I have also connected decoupling capacitor.

  • I'm runing Nano
  • Latest download of MySensors library
  • Radio modul bought from the link on MySensors shop.
  • I run the radio from external 3.3 V (so red cabel on picture is not there anymore)
  • I run the RelayActuator sketch from the samples without any modifications
  • I have only one sensor, no gateway
  • I have tested two different Nano and two different radio

my radio chips say NRF24L01+, however are detected as NRF24L01.

Got 3 of em working perfectly on Uno and Nano...but on pro mini always gettin the f**n "check wires" message...the only difference is the regulator (I'm using arduino pro mini 5V), but i checked and radio is getin 3.3 as it should be.

If someone in Europe needs to get radios fast, try this guy in Finland. He advertises the radios as NRF24L01, but they are in fact NRF24L01+.

gw.begin(NULL, 25);

this sample set id fixed to 25 on this node. At least that was one of my problem with this radios, but my advice is to by new radios the cost is so smal compared to the effort. However it is the shiping that is the problem.

I never inteded to develop any driver so I will simply buy a new batch with more care this time.

you can investigate this but no success guaranteed

//#include "nRF24L01.h" //#include "RF24.h"
and
#define MINIMAL from RF24_config.h

None of the "normal" examples work or give anything over serial.

If someone has too much time on their hands this could be added as a new RFM73 driver in the development branch.

GettingStarted can be used to connect two arduinos. Have you tested this? You told that examples are working.

I don't get "check wires". I just don't get anything.

is your chip recognized as NRF24L01+ or just NRF24L01?

connect wires according to hek's instruction http://www.mysensors.org/build/connect_radio

it could probably work
At least nobody will charge you for the try :)

I haven't had time to test it yet, but it looks very suspicious. I'm pretty sure I ordered via MyS store on Jan 10 (soon after the Ali-links just were introduced). Is it worth the hassle to test or should I throw it straight into the garbage and order a new batch from a proven supplier (which one)?
Bought it from here.

I've wasted some hours because this library uses serial baud rate 115200, not 9600, what is default for other projects - it should be mentioned in proper place, sorry, if it is, but I've not noticed it.

It is mentioned at a few places on the main site. Anywhere particular place it is missing?

I've started from "Building Ethernet Gateway" and finished on "MQTT Gateway", as I use OpenHAB as Controller.

I'm not a geek developer, maybe it is possible to use #define SOFTSPI in main sketch, before including other libraries? It would be simpler, than editing file RF24_config.h for gateway node and sensor node?

Unfortunately the Arduino IDE build system is f**cked up and does not allow this. But I agree that DEBUG and SOFTSPI would had been great to add in the sketch itself.

I'am a new one on this forum, and I've stepped on the same rake like others. So there are some recommendations for other newbies and questions for developers:

  1. I've wasted some hours because this library uses serial baud rate 115200, not 9600, what is default for other projects - it should be mentioned in proper place, sorry, if it is, but I've not noticed it.

  2. Next step for all users, that want to use this great project, should be sketch that outputs NRF24L01 version: my history is, that I've bought 10 NRF's from the same seller (alice***) 2-3 months ago, on chips there is "+" sign, but sketch says, that there is NRF24L01 without "+" :(

  3. What to do for those unlucky, that bought wrong version: maybe it's possible to use these modules with some restrictions, while right modules will arrive? I saw recommendations about sensor node to change speed and comment out while()1) after "check cables", but what to do for gateway node?

  4. I'm not a geek developer, maybe it is possible to use #define SOFTSPI in main sketch, before including other libraries? It would be simpler, than editing file RF24_config.h for gateway node and sensor node?

Thanks!

I have tried using them but without success. I couldn't get them to work at all on the gateway but if I replaced the gateway with + variant and non + on the node then it "almost" worked. I couldn't get the "Auto Id" function to work. I think it has something with Ack to do, i will remember that I have read somewhere that the hardware ack is only implemented in the + variant.

@axillent And me! I started the thread so I have got 10 of the them, maybe something for the MySensors museum!

hm. are the + is missing on top of the nordic chip?

it can be probably still used for mysensors in case of:

  • switching data rate to 1Mbs or 2MBs (old version do not support 250Kbs - default to 1.4)
  • comment out "check wires" check inside Mysensors library
