TCP Socket CommunicationAcademic

The socket communication log file consists of two parts: the header containing the measurement information and the body containing the sensing data. The header contains the measurement information "Data mode, Transmission speed, Accelerometer sensor's range, Gyroscope sensor's range, and data rank" respectively.

For Select mode "Full", Transmission speed "100Hz", Measurement range of Accelerometer "±4g", and Measurement range of Gyroscope "1000dps"

//Data mode  : Full
//Transmission speed  : 100Hz
//Acceleration sensor's range  : 4g
//Gyroscope sensor's range  : 1000dps
//ARTIFACT,NUM,DATE,ACC_X,ACC_Y,ACC_Z,GYRO_X,GYRO_Y,GYRO_Z,EOG_L,EOG_R,EOG_H,EOG_V

Socket client sample

Below is a sample of data reception in Python.

import socket
target_ip = "127.0.0.1" //Change here
target_port = 60000 //Change here
buffer_size = 4096

# 1.Creating a Socket Object
tcp_client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print("tcp_client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)")

# 2.Connect to Server
tcp_client.connect((target_ip,target_port))
print("tcp_client.connect((target_ip,target_port))")

is_end = False
while not is_end:
    # 3.Receive response from server
    response = tcp_client.recv(buffer_size)
    if response == b"":
        is_end = True
    print("[*]Received a response : {}".format(response))

# 4.Terminate the connection
tcp_client.close()
