Well I found the error:

The thing is that the solder bridge was hidden under the plastic header.

@Sparkman @emurr Thanks for the help so far.

Although I didn't mentioned in my start post I made a nice shield containing the NRF24L01+ transceiver and LED's. The base for my shield is a arduino proto shield and it looks like some of the internal shield wiring messes with my serial port and/or my SPI bus .

If I just connect the pins I need for the NRF24L01+ transceiver the shield works fine.

I have some hardware debugging to do but thanks for your help.

Ok, So I got myscontroller running on windows. (Looks good) So now for the rest.

If I use automatic ID assignment I'm still not getting the ID assigned although myscontroller is trying to set the ID.

So since I expected that the NRF24L01+ transceiver could be wrong I just tried swapping the transceivers from the gateway and the sensor. However the ID still can't be assigned by myscontroller.

Any other suggestions on what I can check if the comms is working.

I now also tried the following sketch with the sensor in repeater mode so I'm "forcing" the comms to be alive (at least, I hope) but this also won't work.

So now I have 3 questions:
How do I send a message from myscontroller so that I can test the communication (what message would be good for this)?
Is there a special sketch so I can test the communication between 2 units (gateway and sensor)? ping-pong?
Is there a "advanced debug" option?

Update:

I just edited the temperature sample to include the #define DEBUG statement at the beginning of the temperature transmitter sample, also I added a 10uF capacitor on the supply lines of the NRF24L01+ transceiver on the side of the temperature transmitter.

The debug output is below:

sensor started, id 255
req node id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,st=ok:
<repeated x times>
<I also have lines containing:>
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,st=fail:

Hope this helps

Edit:
I'm wondering: is there a way to do some "ping-pong" between the gateway and my sensor so I can test the range and/or look for problems in the communication (and maybe even start complaining about the NRF24L01+ transceiver with my supplier is that is the case..)

Hi,

I'm trying to connect a temperature sensor to a server. However the automatic assignment of the ID seems to be failing.

The temperature sensor is build according to the default sample: http://www.mysensors.org/build/temp. (controller = Mini Arduino Pro 8MHz, 3V3)
The gateway is a serial gateway with the LEDs as added bonus according to: http://www.mysensors.org/build/serial_gateway and http://www.mysensors.org/build/advanced_gateway. (controller - Arduino Uno, 16MHz, 5V)
To wrap-up the hardware site I didn't install the capacitors for the NRF24L01+ transceiver but the communication itself seems to be OK.
As a server I'm using a Raspberry Pi B2.

On the software site I have the following:
The Temperature sensor is running the sample found on http://www.mysensors.org/build/temp.
The gateway is running the sample found on http://www.mysensors.org/build/serial_gateway.
And on my PI I'm using the NodeJsController from https://github.com/mysensors/Arduino/tree/master/NodeJsController with Node 12.0 and MongoDB (as per sample).

Now I do the following: The gateway is connected. Start the NodeJsController (with "node NodeJsController.js"), (re)start the Temperature sensor.
The output from the console is below:

If I now edit line 26 in the temperature controller sample to:

gw.begin(NULL, 1, false);

The output is the following:

Working!!!

So there seems to be a problem with the automatic assignment of the IDs.
I already tryed the to erase the eeprom on the temperature controller but this din't work as well (sketch: https://codebender.cc/sketch:108438)

Hope you can help.
