蓝牙案例¶
- 跟WiFi案例相同，编译上传固件
- 在案例文件夹里找到app-release.apk，上传到手机安装
- 手机蓝牙，连接电子纸驱动板
- 打开App，上传图片
macOS系统¶
- 安装驱动很麻烦，不支持，不推荐使用macOS
I found that macOS High Sierra has blocked the SiLabs kernel extension. Here are steps to allow this extension: Go to "System Preferences" -> "Security & Privacy" In the bottom of the window, you will see a message "System software from developer "SiLabs" was blocked from loading." Click on "Allow" button Restart your Mac Now my device is listed as /dev/cu.SLAB_USBtoUART and everything work as expected.
