IWR1443BOOST: Reading via Serial with Python

Hi,

I'm currently trying to get the breath and heart rate outputs via USB without using the vital signs visualiser. I have parsed the configuration code via the command line interface and the EVM is flashed with the pre-built vital-signs detection binary file.

As mentioned in other threads, this is my python code:

import serial
import time
import numpy as np

# Change the configuration file name
configFileName = 'profile_2d_VitalSigns_20fps.cfg'

CLIport = {}
Dataport = {}
byteBuffer = np.zeros(2**15,dtype = 'uint8')
byteBufferLength = 0;
dataBin = [None] * 288

magicWord = [2, 1, 4, 3, 6, 5, 8, 7]
magicWord = [bytes(i) for i in magicWord]

# Byte sizes for different values
magicWord  = 8
fftOrPeak  = 4

# ------------------------------------------------------------------

# Function to configure the serial ports and send the data from
# the configuration file to the radar
def serialConfig(configFileName):
    
    global CLIport
    global Dataport
    # Open the serial ports for the configuration and the data ports
    
    # Raspberry pi
    #CLIport = serial.Serial('/dev/ttyACM0', 115200)
    #Dataport = serial.Serial('/dev/ttyACM1', 921600)
    
    # Windows
    CLIport = serial.Serial('COM4', 115200)
    Dataport = serial.Serial('COM5', 921600)

    # Read the configuration file and send it to the board
    config = [line.rstrip('\r\n') for line in open(configFileName)]
    for i in config:
        CLIport.write((i+'\n').encode())
        print(i)
        time.sleep(0.01)
        
    return CLIport, Dataport


def processData(dataBin):
    # Alter to 4-byte data in array form 1 byte/element
    breathFFT = dataBin[52:56]
    breathFFT = breathFFT[::-1]
    heartFFT  = dataBin[56:60]
    heartFFT = heartFFT[::-1]
    
    # Remove b value in hex
    breathFFT = [s.hex() for s in breathFFT]
    heartFFT  = [s.hex() for s in heartFFT]

    # Join arrays together to form 4 byte value
    breathFFT = float.fromhex("".join(breathFFT))
    heartFFT  = float.fromhex("".join(heartFFT))

    return breathFFT, heartFFT

def readAndParseData(dataBin, Dataport):
    readBuffer = Dataport.read(Dataport.in_waiting)
    dataBin = dataBin[Dataport.in_waiting:]
    dataBin.append(readBuffer)

    



# -------------------------    MAIN   -----------------------------------------  

# Configurate the serial port
CLIport, Dataport = serialConfig(configFileName)

print(CLIport)
print(Dataport)

print("reading")

while True:
    if Dataport.in_waiting > 0:
        try:
            readAndParseData(dataBin, Dataport)

            if dataBin[0:8] == magicWord:
                breathFFT, heartFFT = processData(dataBin)
            
                print(breathFFT,heartFFT)
        
        except KeyboardInterrupt:
            CLIport.write(('sensorStop\n').encode())
            CLIport.close()
            Dataport.close()

However, I am not getting any outputs from the evaluation module. When running the vitalSignsDemo_GUI.exe visualiser with the same cfg file, the GPIO_1 LED lights up and the data is transmitted to the visualiser without any problems, using the same COM ports.
The cfg parameters are as follows:
