Rs232 comm between NVIDIA and Roboteq

[scoutingrobot]

Hello,

I am trying to send !VAR command values from nvidia to roboteq drive controller.
Successfully can send !EX and !MG ASCII strings but not able to send ‘!VAR 1 250’

Could you please help me with this issue.
I have attached the code below:

import time
import serial

ser = serial.Serial(
port=”/dev/ttyTHS1″,
baudrate=115200,
bytesize=serial.EIGHTBITS,
parity=serial.PARITY_NONE,
stopbits=serial.STOPBITS_ONE,
)

command = ‘!EX’ +’ \r’ //Command goes through and activates E-Stop
ser.write(command.encode())
print(“E-Stop ON”)

command = ‘!VAR 1 250′ +’ \r’ //Not able to send this command
ser.write(command.encode())
print(“Forward”)

Hello,

Unfortunately, we are not familiar with this command. This question is probably better for the RoboteQ forum.
