AT组件无法初始化成功怎么解决？

• at_client_t at_client_get(const char *dev_name)
  
• {
  
•     int idx = 0;
  
• 
  
•     RT_ASSERT(dev_name);
  
•     rt_kprintf("get AT client object by device name: %sn", dev_name);
  
•     rt_kprintf("at_client_table[idx].device->parent.name: %sn", at_client_table[idx].device->parent.name);
  
•     for (idx = 0; idx < AT_CLIENT_NUM_MAX; idx++)
  
•     {
  
•         rt_kprintf("at_client_table[idx].device->parent.name: %sn", at_client_table[idx].device->parent.name);
  
•         rt_kprintf("idx: %dn", idx);
  
•         if (rt_strcmp(at_client_table[idx].device->parent.name, dev_name) == 0)
  
•         {
  
•             rt_kprintf("at_client_table[idx].device->parent.name: %sn", at_client_table[idx].device->parent.name);
  
•             return &at_client_table[idx];
  
•         }
  
•     }
  
•         rt_kprintf("at_client_table[idx].device->parent.name: %sn", at_client_table[idx].device->parent.name);
  
•     return RT_NULL;
  
• }
  

下面是打印的结果

• get AT client object by device name: uart3
  
• at_client_table[idx].device->parent.name: (NULL)
  
• at_client_table[idx].device->parent.name: (NULL)
  
• idx: 0
  

说明at_client_table[idx].device->parent.name没有进行初始化，我需要在哪里初始化它
