# Supported versions of AWS IoT Device Tester
<a name="dev-test-versions-afr"></a>

This topic lists supported versions of AWS IoT Device Tester for FreeRTOS. As a best practice, we recommend that you use the latest version of IDT for FreeRTOS that supports your target version of FreeRTOS. Each version of IDT for FreeRTOS has one or more corresponding versions of FreeRTOS that it supports. We recommend that you download a new version of IDT for FreeRTOS when a new version of FreeRTOS is released. 

By downloading the software, you agree to the AWS IoT Device Tester License Agreement contained in the download archive.

**Note**  
When you use AWS IoT Device Tester for FreeRTOS, we recommend that you update to the latest patch release of the most recent FreeRTOS-LTS version. 

**Important**  
As of October 2022, AWS IoT Device Tester for AWS IoT FreeRTOS Qualification (FRQ) 1.0 doesn't generate signed qualification reports. You can't qualify new AWS IoT FreeRTOS devices to list in the [AWS Partner Device Catalog](https://partners.amazonaws.com/qualified-devices) through the [AWS Device Qualification Program](http://aws.amazon.com/partners/programs/dqp/) using IDT FRQ 1.0 versions. While you can't qualify FreeRTOS devices using IDT FRQ 1.0, you can continue to test your FreeRTOS devices with FRQ 1.0. We recommend that you use [IDT FRQ 2.0](https://docs.aws.amazon.com/freertos/latest/userguide/lts-idt-freertos-qualification.html) to qualify and list FreeRTOS devices in the [AWS Partner Device Catalog](https://partners.amazonaws.com/qualified-devices).
