rosserial_server wifi connection Raspberry pi ESP8266

edit

Hello, dear community. I am facing problems with rosserial_server.

I am using this command to connect the ESP8266 with the Raspberry pi 4 via wifi.

roslaunch rosserial_server socket_node

Indeed using rqt_graph I can see that the rosserial_server is activated but is not subscribing any topic. I've checked again my python code and is good because two days ago the rosserial_server was working without problems.

Right now, rosserial_server is running but is not subscribing to the topic "/Topic_data_over_wifi"(it seems is not receiving anything in the port 11411), but the ESP8266 is using ROS and it's pointing to the port 11411 and connecting to the topic "/Topic_data_over_wifi". I get this response when I run rostopic list

• /commands_from_master_node
• /topic_data_over_wifi
• /rosout
• /rosout_agg

I need to find a way to connect the ESP82 and the Raspberry pi 4 via wifi using ROS (not using rosrun rosserial_python serial_node.py tcp) I've already looked at this Multiple_TCP_connections post but didn't find anything that could solve my problem. Any help I would appreciate!
