Solution: BLE HID Selfie¶
1 功能概述¶
此项目演示模拟蓝牙自拍杆功能。
2 环境要求¶
board: pan1080a_afld_evb
uart (option): 显示串口shell
测试硬件:智能手机
PC工具: 软件shell工具（支持串口，波特率921600）
3 编译和烧录¶
项目位置：zephyr\samples_panchip\solutions\ble_hid_selfie
统一的配置、编译、下载工具正在开发中，当前可以使用脚本进行编译和下载。
脚本位置：quick_build_samples\solutions\ble_hid_selfie.bat。
打开脚本后默认会编译项目，编译完成时，可输入字符进行后续下载等操作:
Input the keyword to continue:
'b' build 编译项目
'r' make clean and rebuild 重新编译项目
'f' flash download 下载
'e' erase chip 擦除芯片
'o' open project by VS Code 打开 `VS Code`，可查看源码，执行编译下载等
others exit 退出
wait input:
4 演示说明¶
将ble_hid_selfie烧录至EVB板后，使用shell工具连接上EVB开发板（波特率921600），会显示如下log。通过连续双击tab可以显示出当前可用的命令。

然后我们就可以通过支持的test命令来模拟蓝牙自拍杆的相关动作

相应命令支持的函数可以参考shell命令实现：
SHELL_STATIC_SUBCMD_SET_CREATE(sub_test,
SHELL_CMD(photos, NULL, "Take Photos command", cmd_test_photos),
SHELL_CMD(ac_home, NULL, "AC Home command", cmd_test_ac_home),
SHELL_CMD(vol_up, NULL, "Volume up command", cmd_test_vol_up),
SHELL_CMD(vol_down, NULL, "Volume down command", cmd_test_vol_down),
SHELL_CMD(raw_hex, NULL, "RAW Hexgroup command", cmd_test_raw_hex),
SHELL_SUBCMD_SET_END /* Array terminated. */
);
SHELL_CMD_REGISTER(test, &sub_test, "HID Over GATT Test commands", NULL);
