Prior to the introduction of the IIH SDK, developing Edge Apps for Industrial Edge Devices was a fragmented and time-consuming process. Developers had to repeatedly install and run their apps on Edge Devices to identify and fix issues. This iterative cycle of deploying, testing, debugging, and redeploying was inefficient and prolonged the development timeline. The IIH SDK was developed to address these challenges by providing a more cohesive and efficient development workflow.
