Hi sorry quite busy right now. Might review over the weekend.

if your file is csv then just read the file using pandas, construct the message yourself and send it over UDP.

That's what I am doing right now and it does the trick

example:

df_csv = pd.read_csv(PATH_CSV)
time = df_csv['loggingTime(txt)']


quat_w = df_csv['motionQuaternionW(R)']
quat_x = df_csv['motionQuaternionX(R)']
quat_y = df_csv['motionQuaternionY(R)']
quat_z = df_csv['motionQuaternionZ(R)']

yaw = df_csv['motionYaw(rad)']
pitch = df_csv['motionPitch(rad)']
roll = df_csv['motionRoll(rad)']

UDP_IP = "0.0.0.0"
UDP_PORT = 5005
START_indx = 9350
END_indx = 10000
MESSAGE = 'w' + str(quat_w[1]) + 'wa' + str(quat_x[1]) + 'ab' + str(quat_y[1]) + 'bc' + str(quat_z[1]) + 'c'

print("UDP target IP:", UDP_IP)
print("UDP target port:", UDP_PORT)
print("message:", MESSAGE)
print(f"Time {time[1]}")

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDP
i = START_indx
# while True:
while i < END_indx:
    MESSAGE = 'w' + str(quat_w[i]) + 'wa' + str(quat_x[i]) + 'ab' + str(quat_y[i]) + 'bc' + str(quat_z[i]) + 'c'
    sock.sendto(bytes(MESSAGE, "utf-8"), (UDP_IP, UDP_PORT))
    print(f"Time: {time[i]}, i: {i}")
    i += 1
    input()

note: I use "input()" so the code runs when I want it so I can go over line by line
