这家伙很懒，什么也没写！

AT组件是不是不支持十六进制的接收？

```c
static int at_recv_readline(at_client_t client)
{
    rt_size_t read_len = 0;
    char ch = 0, last_ch = 0;
    rt_bool_t is_full = RT_FALSE;

memset(client->recv_buffer, 0x00, client->recv_bufsz);
    client->cur_recv_len = 0;

while (1)
    {
        ch = at_client_getchar(client);

if (read_len < client->recv_bufsz)
        {
            client->recv_buffer[read_len++] = ch;
            client->cur_recv_len = read_len;
        }
        else
        {
            is_full = RT_TRUE;
        }

/* is newline or URC data */
        if ((ch == '\n' && last_ch == '\r') || (client->end_sign != 0 && ch == client->end_sign)
                || get_urc_obj(client))
        {
            if (is_full)
            {
                LOG_E("read line failed. The line data length is out of buffer size(%d)!", client->recv_bufsz);
                memset(client->recv_buffer, 0x00, client->recv_bufsz);
                client->cur_recv_len = 0;
                return -RT_EFULL;
            }
            break;
        }
        last_ch = ch;
    }

#ifdef AT_PRINT_RAW_CMD
    at_print_raw_cmd("recvline", client->recv_buffer, read_len);
#endif

return read_len;
}
```
