20241108通过iperf3确认中科创达的高通CM6125的WIFI的网速【失败】
2024/11/8 15:43

由于以太网不能用，那就测试一下WIFI，iperf3链接/测试异常。
一般认为可能的原因有：
1、CM6125开发板的WIFI不带天线，影响性能。
2、CM6125的Android10自带的iperf3有问题。【可能性比较小！】
3、CM6125自带的WIFI/BT模块坏掉了。

开发板自带3个HDMI口，特别拉风！【有一个HDMI IN，剩下的2个应该是HDMI OUT】
但是在Android10下一个都不能用！^_装逼失败的典型吗？

显示：通过 VYSOR 虚拟桌面工具查看桌面。

中科创达的高通CM6125模块，出厂默认是Android10，看文档可以支持Android13和Ubuntu的系统。
由于公司需要评估CM6125开发板。

cm6125默认内置的 Android10 的测试结果：
1、4个USB3.0接口，插鼠标都没有反应。OTG接口通过转接头插入，鼠标红色。但是既没有LCD，HDMI也没有显示，无法确认接鼠标可用。
2、WIFI/BT是内置的？WIFI是 WIFI5？6？7？理论网速？实测网速？
BT是BT4.0？5.0？
3、默认内置的以太网RJ45是不能用的？

1、以太网 RJ45的灯不亮。这条网线昨天用过。链接过RK3566开发板
2、鼠标接 USB3.0接口不亮【4个都不行】
3、WIFI 可以连AP，ping通，iperf3连接不上
