奇怪了，发现以前的开发板蓝牙功能正常。

whycan晕哥 LV 9

对比发现是CTS悬空了。

whycan晕哥 LV 9

用镊子短路CTS到GND就正常。

whycan晕哥 LV 9

OK

BedRock LV 6

whychan PI 再次拖更

whycan晕哥 LV 9

@bedrock
这个感觉可以通过软件修复。

tigger LV 7

@whycan
搞A133 碰到一模一样问题，

CTS悬空了，飞线到GND就好了，应该串口是没有收到握手信号。

@whycan 晕哥，厂家的8723DS的BT的文件发一份呀

whycan晕哥 LV 9

@sora1874
您要哪个文件，SDK里面都有了，用find命令查找一下就可以了。

sora1874 LV 5

@whycan 您的tina2.0有RTL8723DS的包？

whycan晕哥 LV 9

@sora1874
从别的tina sdk 抽出来的。

sora1874 LV 5

@whycan ....购买模块时候，模块厂商一般提供的有软件包

dyd2022 LV 3

@whycan 大佬请教下我在d1-h上8723ds的wifi能正常使用了，蓝牙和上面日志一样启动不了，蓝牙还需要做哪些配置吗？

whycan晕哥 LV 9

@dyd2022
蓝牙使能脚有没有拉高?

dyd2022 LV 3

@whycan 咋看使能脚有没有拉高呀

whycan晕哥 LV 9

@dyd2022

这两个手动拉高试一试．

dyd2022 LV 3

@whycan 这两都是高电平状态
