LAUNCHXL-CC26X2R1: 获得设备列表失败

硬件：cc26x2r1

sdk：5.20

ccs：10.3.0

RTLS UI：1.4.1.4

你好，

本人使用一个coordinator和一个responder搭建的AOA测量系统，烧录后就打开UI，发现无法识别到设备，一直在搜索设备，如下图所示。

后台log如下图所示

我还尝试使用其他版本的sdk，发现并无此问题。具体的配置如下：

sdk：4.30
CCS：9.2.0
firmware：3.0.0.5(刷过固件)

请问怎么解决这个问题，感谢！

Kevin Qiu1：

我在SDK5.20上测试了一下没有出现问题，刚打开ui界面时尝试使用Ctrl+F5或者Fn+F5刷新

另外注意浏览器使用chrome

Zhu Dekang：

感谢Kevin，问题得到解决。

还想请教一下，sdk 5.20如何测量AoA数据并显示出来。

再次感谢，期待你的回复。

Kevin Qiu1：

从SDK5.20开始删除了对AOA角度计算的支持，现在只提供原始IQ数据的采集

Note

For the past few years, we have been improving our Real Time Localization System (RTLS) toolbox. Today, our SimpleLink CC26x2 Bluetooth LE wireless MCUs and software stack (BLE5-Stack) solution elements enable development of Bluetooth 5.2 compliant direction-finding solutions based on Received Signal Strength Indication (RSSI) and Angle of Arrival (AoA), with each leveraged to assist customers building advanced direction-finding applications in various segments, such as automotive and industrial.

It should be understood that an actual end product implementation incorporating AoA direction finding locator capabilities (1) requires advanced knowledge and further integration by the customer that would not ordinarily be required in a product using Bluetooth LE for communication purposes. Some challenges the customer may be required to address with AoA in their locator product include, but are not limited to, the following:

Embedded or system-level algorithms to achieve desired localization performance/angular accuracy while mitigating the presence of undesired signals (e.g. multi-path reception) in various operating environments
Antenna design to match the end product’s industrial design constraints and/or performance expectations

With Bluetooth-qualified AoA capabilities now included in the SDK, we are making the following modifications in our support for AoA:

The BOOSTXL-AOA antenna evaluation board will no longer be available for purchase after September 30, 2021.
For SDK 5.20 and later, in conformity with Bluetooth Low Energy specifications, RTLS examples only support “raw I/Q data” mode. I/Q data can be used for the development of algorithms that will need to be specific to your end product implementation.
For SDK 5.20 and later, support for Angle of Arrival (AoA) has been removed from the RTLS visual demo.

The content of SimpleLink CC13x2 / CC26x2 SDK version 5.10 and earlier releases will remain accessible; however, limited E2E support for AoA will be provided in these earlier SDKs.

(1) Implementation incorporating AoA direction finding target capabilities do not require such advanced knowledge and can directly leverage the rtls_responder example provided in the SDK as described in the Bluetooth Low Energy Angle of Arrival (AoA) for target devices
