# 🔧硬件配置：
STM32F407ZGT6
中移物联网 ML307A-DCLN 4G模块

# 🧾软件环境：
RT-Thread Studio [2.2.6]
rt-thread [5.1.0]
mbedtls [latest]

# 🧷软件包配置：

# 💡目前方案：
通过AT_Device例程进行注册
```c
#define ML307_SAMPLE_DEIVCE_NAME        "ml3070"
#define ML307_SAMPLE_CLIENT_NAME        "uart2"
#if !defined (ML307_SAMPLE_POWER_PIN)
    #define ML307_SAMPLE_POWER_PIN      0x1C
#endif
#if !defined (ML307_SAMPLE_STATUS_PIN)
    #define ML307_SAMPLE_STATUS_PIN     0x1E
#endif
#if !defined (ML307_SAMPLE_RECV_BUFF_LEN)
    #define ML307_SAMPLE_RECV_BUFF_LEN  4096
#endif
#if !defined (AT_DEVICE_CLASS_ML307)
    #define AT_DEVICE_CLASS_ML307       0xFFFFU
#endif
static struct at_device_ml307 ml3070 =
{
    ML307_SAMPLE_DEIVCE_NAME,
    ML307_SAMPLE_CLIENT_NAME,

ML307_SAMPLE_POWER_PIN,
    ML307_SAMPLE_STATUS_PIN,
    ML307_SAMPLE_RECV_BUFF_LEN,
};

static int ml307_device_register(void)
{
    struct at_device_ml307 *ml307 = &ml3070;

return at_device_register(&(ml307->device),
                              ml307->device_name,
                              ml307->client_name,
                              AT_DEVICE_CLASS_ML307,
                              (void *) ml307);
}
INIT_APP_EXPORT(ml307_device_register);
```
加入NTP网络校时
校时后执行`tls_test`命令后的日志如下

# ❓问题总结：
通过打印的日志发现，mbedTLS例程运行后的错误是**证书未由受信任的CA正确签名**，是什么原因呢？还是说我哪里没配置好呢？？
