Chapter 9. Advanced Photon
In this chapter, you will learn about some of the more advanced features of the Photon and Core.
Configuring a Photon Using USB
Although the Tinker app is a very convenient way of setting up a new Photon/Core, it is not the only way of telling a new device your WiFi credentials. The USB socket on a Photon or Core is not just for supplying the device with power; it can also be used to communicate with your computer over USB.
You can pass WiFi credentials to your Photon/Core by using the USB connection and a serial communication program. If you have a Mac or Linux computer, you already have a built-in utility (called screen) for this kind of serial communication over USB.
