Building and flashing ESP-IDF v3
The environment is now ready to build and flash a project. In this case, we use “hello world” as a
sample project.
This project will print out “Hello World” ten times on the UART and then reboot.
To build this sample project, go to the “hello world” folder using the following command:

com port that is used to flash NINA-W10 is modified.
Use the arrow keys to navigate and select the “Serial flasher config” as shown in Figure
