SOLVED: Problems registering MySensors node

6 years 5 months ago - 6 years 5 months ago #1403 by ArneiO
I am attempting to bring to life my first node using an NRF24L01+, after having successfully implemented several ESP8266 nodes.
I am running V0.8 EasyIoT server on an Rpi2, and have connected an NRF24L01+ to the signals indicated in the diagram in the Server Installation Guide . Using the same signals but different pins since I am on an RPi2.
My node is an arduino miniproclone with an NRF20L01+ and a DHT-11. I have uploaded to the arduino the HumiditySensor sketch that is an example in the Arduino IDE after having installed the MySensor library.
I have not managed to register the driver. I push the button, power the node, waits... and timeout. I have verified that the Channe number, the Base Radio Id and data rate is the same as in the MyConfig.h file.
The server window shows the following:

The serial monitor connected to the node shows absolutely nothing.
By inserting debug printouts in in the sketch I can say that it stops at gw.begin() in setup().

Can anyone enlighten me as to what I might be doing wrong? Is there any way of checking that the NRF20L01 sitting on my Rpi2 is detected and operational?

PS: The arduino sketch contains several Serial.println("whatever") without any Serial.begin() in the setup(). I am not able to get any response from my Aardunio without inserting a Serial.begin(). I am puzzled as to this seeming error, and wonder if there are other issues in the sketch.

This is the Arduino sketch.

Your NRF24l01 is properly connected to RPI. If it is not properly connected you see "Check wires message". Try to enable debug in MySensors library on node side to see what's happening.

OK, so I know I'm OK server side. Good!

I enabled debug in MyConfig.h library, and got "check wires" message from arduino on node side.

I have wired according to Connection diagram on this page .
I re-checked, and the wiring now, it is according to that diagram.

EDIT
...and now it registered! :cheer:
The wiggling of wires on my breadboard during the check apparently did the trick. Thank you!
