CM311-1a启用蓝牙遇到问题，求助

[twallpasser]

盒子是从咸鱼上买来刷好了armbian系统的。 参考#1513提供的方法，我发现系统里已经有rtl8761b的固件和配置了，然后ttyAML1设备也有。rtk_hciattach是拉了这个仓库 https://github.com/radxa/rkwifibt.git 用里面的源码realtek/rtk_hciattach编译的。 按照前面的方法我写了各测试的脚本

armbian:~:# cat ./hci_test.sh
#!/bin/zsh
/usr/bin/rtk_hciattach -n -s 115200 ttyAML1 rtk_h5 &
gpioset -s 1 -m time 0 82=0
gpioset 0 82=1

但是执行到下载固件的时候就出错了

armbian:~:# ./hci_test.sh

你看看从哪下载，这个网站现在能不能打开，或者你的网络是否能访问这个网站

看起来这个过程没有从远程服务器下载数据，只是读写串口。

谢谢。解决了，参考了这个回答 https://github.com/lwfinger/rtl8723bs_bt/issues/31#issuecomment-536043830 看起来是配置不对导致的。
