The SanDisk® iXpand is a family of storage accessories for devices running Apple’s iOS. iXpand devices enable transfer and storage of photos, music, videos and files between iPhones, iPads, PCs and Mac computers. iXpand accessories are accessible over Lightning® and USB connectors.
The development workflow is to integrate the iXpand SDK into your app, perform your validation process, and submit your app to Western Digital to obtain the Product Plan ID (PPID) code that will be asked for when you submit your app to Apple.
The SanDisk iXpand SDK enables third party application developers to access and manage iXpand devices from their own iOS applications through the Lightning interface.
