Flex SDK v3.x Range Test Demo User's Guide#

NOTE: This section replaces UG471: Flex SDK v3.x Range Test Demo User's Guide. Further updates to this user guide will be provided here.

This user's guide describes an easy way to evaluate the link budget of the Wireless Gecko EFR32 devices using Silicon Labs' Radio Abstraction Interface Layer (RAIL) by performing a range test between a transmitter and any number of receiver nodes. Range Test is a standalone test application that creates a radio link between the evaluation kits and sends a predefined number of packets from the transmitter side to the receiver. The Range Test demo implements packet error rate (PER) measurement. PER is a commonly-used technique for measuring the quality of RF links in wireless systems under particular conditions. Flex SDK 3.x contains multiple Range Test applications that enable the physical layer's (PHY) evaluation for a custom protocol or for standard protocols supported by RAIL (IEEE802.15.4g and Bluetooth LE).

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.
