Hello my friends,
I am working on a project where wireless sketch upload into remote Arduino (Atmega 328p) is needed. I have tried to use this tutorial:

But Arduino IDE throws "avrdude: ser_open(): can't open device "\\.\COM6": Access is denied." when I hit "Upload" in Arduino IDE.
Maybe I have Xbees set up wrongly, I could not find arduino settings file in that tutorial attached (author said it is attached). But I don't know, problem might be somewhere else.
Do you think you could help me to make this work?
