Now you can code without cables! In this guide, you’ll be able to use any iOS device, such as an iPhone or an iPad, to easily transfer files to a Circuit Playground Bluefruit (CPB). This is made possible by the new File Glider Application for iOS. This app allows you to connect to a CPB from your iOS device then you can transfer files to the CPB through the Files app. Once connected, you’ll also be able to create, move, rename and delete files and directories through the Files app. Additionally, the File Glider app enables you to write and edit code directly to the CPB!
This will be demonstrated using an example Rainbow Touch program where the colors of the NeoPixel LEDs on the CPB can be changed with the touch of any I/O pin.
To power the CPB SEPARATELY from your computer (more on this later), you have a choice of:
Alternatively, you can use the USB cable from your computer and plug it into this adapter to power the CPB without plugging into a computer:
