以下代码存在一些错误：

1. 在函数 `btblecontroller_em_config()` 中，函数的最后缺少一个右大括号 `}`。
2. 在函数 `main()` 中，代码缺少头文件引用，需要添加头文件 `bluetooth.h`、`ble_gap.h` 和 `ble_gatt.h`。
3. 在函数 `main()` 中，变量 `raw_data` 未定义，需要先定义并赋值。
4. 在函数 `main()` 中，调用 `bluetooth_set_device_name()` 函数和 `bluetooth_start_advertising()` 函数之前，需要先调用 `bluetooth_init()` 函数初始化蓝牙。
5. 函数 `gatt_event_handler()` 中，变量 `raw_data` 未定义，需要先定义并赋值。

修改后的代码如下：
