Customizing Applications with Silicon Labs Connect v3.x#

NOTE: This section replaces UG435.04: Customizing Applications with Silicon Labs Connect v3.x. Further updates to this user guide will be provided here.

This chapter of the Connect v3.x User’s Guide describes how to use Connect components, callbacks, and events to provide developer-configurable features and application behavior. The Connect stack is delivered as part of the Silicon Labs Proprietary Flex SDK v3.0 and higher. The Connect v3.x User’s Guide assumes that you have already installed the Simplicity Studio® 5 development environment and the Flex SDK, and that you are familiar with the basics of configuring, compiling, and flashing Connect-based applications.

The information in this chapter is designed for developers who are new to Connect. If you are experienced with Connect v2.x in Simplicity Studio 4, see AN1254: Transitioning from the v2.x to the v3.x Proprietary Flex SDK. The Connect v3x User’s Guide is a series of documents that provides in-depth information for developers who are using the Silicon Labs Connect Stack for their application development. If you are new to Connect and the Proprietary Flex SDK, see QSG168: Proprietary Flex SDK v3.x Quick-Start Guide.

Proprietary is supported on all EFR32FG devices. For others, check the device's data sheet under Ordering Information > Protocol Stack to see if Proprietary is supported. In Proprietary SDK version 2.7.n, Connect is not supported on EFR32xG22.
