* Description: 于ql_atcmd_async_init中注册的回调函数
*
* Parameters: errno: 接口返回结果,参考枚举QL_AT_RESP_STATUS_E
* buffer: AT指令执行返回结果,即urc内容
* len: AT指令执行返回结果的长度
*
* Notes: 1.此回调在ql_atcmd_async_init中注册,在收到AT的返回结果后被执行,从
* 而上报给app端,此回调中请不要使用过大的数组等变量,因为这个回调的栈是在
* ql_atcmd_async_init中第二个参数创建的一个AT结果处理task内,栈大小为指定
* 的stack_size,所以回调中请注意不要造成栈溢出;
* 2.此回调中不要执行过多耗时操作,以防止阻塞接收AT处理结果的流程,导致
* 下一次AT回调不及时等问题。
