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 rosserialserver socketnode

Indeed using rqtgraph I can see that the rosserialserver 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, rosserialserver is running but is not subscribing to the topic "/Topicdataoverwifi"(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 "/Topicdataover_wifi". I get this response when I run rostopic list

• /commandsfrommaster_node
• /topicdataover_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 rosserialpython serialnode.py tcp) I've already looked at this MultipleTCPconnections post but didn't find anything that could solve my problem. Any help I would appreciate!
