Send msg to TCP server (format: bytes) 

You will need to send the message, especially the id to the TCP server right after connection. Thus, the TCP server could recognise the robot id.

Examples: sensors: b'{"time": "2022-07-22 16:14:33","location":'Location1',"id": "humidity", "value": 15}' b'{"time": "2022-07-22 16:14:33", "location":'Location1',"id": "temperature", "value": 5}'

robots: b'{"time": "2022-07-22 16:14:33", "id": "RoboticDog_mobilerobot_0", "action": "location response", "location": {"X":"33", "Y":"99", "Yaw":"99"}}'

actuators: b'{"time": "2022-07-22 16:14:33", "id":"Home_actuator_0", "action": "location response", "location": {"Servo_motor":{"Button": "1", "Reply": "0", "Display": "0"},"DC_motor":{"Button": "0", "Reply": "0", "Display": "0"},"Step_motor":{"Button": "0", "Reply": "0", "Display": "0"}}}'

Please read notes.

We write a shell script for quickly start. 

Please note that you should modify the server_start.sh before everything start. 

Please change the dir of virtual Env if you use conda, otherwise, comment it.

Then the django and tcp server will be started. The port of this django is 8000 and the port of the tcp server is 9000.
