nanode RF with RED LED

I'm just done soldering my Nanode RF together but when I connect it with my computer (MAC OS - USB cable) only the RED LED turns on. Is this normal? When I want to do the blink test (with the Ardunio Software) nothing happens... Can someone please help me out of this?


I also soldered the RFM12 module and 82mm antenna, is this the problem??

Re: nanode RF with RED LED

FWIW my NanodeRF (433 MHz) has only ever had the red LED on when in operation.  The only part of the NRF that I have not tested is the ethernet interface.  The radio works and picks up the RF signal from my one emonTx.  Perhaps try loading sample sketches before you get too worried.  Good luck!

Re: nanode RF with RED LED

You need to change the Blink example code, it assumes the LED is connected to pin 13 as explained in the comment:

  // Pin 13 has an LED connected on most Arduino boards:

Check the pin list for the Nanode at and you can see: 

Digital 5 Green LED
Digital 6 Red LED

So you should change the Blink example to

  digitalWrite(5, HIGH);   // set the LED on
  delay(1000);              // wait for a second
  digitalWrite(5, LOW);    // set the LED off
  delay(1000);              // wait for a second

This will blink the Green LED.
