      I have realized that it was not working because I was not using the complete circuit.

      Now I have built with the complete circuit (below), and stopped getting the error in the getConfiguration routine.

      Now I will try to make a simple communication using the Part 1 tutorial and will report back with the results.

      Thank you!

        Hello. Thanks a lot for the tips.

        I have enabled the debugging mode and now I’m getting the following message in the serial monitor.

        I checked all wires multiples times with multimeter and have redone all wire connections. Do you have any insight on what may be going wrong?

          Thanks for the help.

          I have connected the AUX to pin 4 from Arduino. However I’m still getting the error message “No response from device! (Check wiring) 12”.

          Which of the resistors in the circuit are you refering to?

            I decided to try switching to Sleep Mode and check what the Get Configuration code would output for each of my circuits.

            Output for Arduino 1:

            Does this give us any information on where there might be a problem?

            Thanks for the help.
