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: pan108xxb5_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¶
例程位置:zephyr\samples_panchip\solutions\ble_hid_selfie
使用 ZAL 工具可以对其进行编译、烧录、打开 VS Code 调试等操作。关于 ZAL 工具的详细介绍请参考:Zephyr APP Launcher 工具介绍。
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);
