这一模块的思路和前面的语言控制模块很相似,差别只是调用TCP 去控制
废话少说,放码过来

编译执行:
编译:
make
发送到arm-64平台
scp ./obj/smarthome orangepi@192.168.1.11:/home/orangepi
执行:
sudo -E ./smarthome
/遇到如下报错 -- 解决:
scp: /home/orangepi/smarthome: Text file busy
kill -9 进程即可
kill之后成功了
bind: Address already in use
要解决这个问题,您可以尝试以下步骤:
-
查找并关闭现有进程:使用
netstat
、lsof
或ss
命令来查找正在监听该端口的进程,并关闭它。sudo netstat -tulnp | grep [端口号] # 或者 sudo lsof -i :[端口号] # 或者 sudo ss -tulnp | grep [端口号]
找到进程ID(PID)后,使用
kill -9
命令来结束该进程。 -
重启计算机:如果无法确定哪个进程正在使用端口,或者无法结束该进程,您可以考虑重启计算机。
-
使用不同的端口:如果您只是想要快速测试您的应用程序,并且不关心特定的端口号,您可以尝试使用另一个端口。
TCP验证:
(注意发送格式 16进制)
否则你发送的数据很可能变成这样
