MegaPi Python Callbacks Problem

#1

Hello,
Has anybody found a good solution to get sensor values to the main function (or any other function).
I call
bot.ultrasonicSensorRead(Slot,onRead)
And from
def onRead(sensorData):
…
I would like to return sensorData to use it where bot.ultrasonicSensorRead was called and I haven‘t found any solution.
Can anyone help?
Thanks

I have been using the PI to talk to my orion, Here is my test code for the ultrasonic:

tst program to talk to makeblock

from megapi import *
distance = 123

def onRead(v):
global distance
print(“distance:”+str(v)+" cm")
distance = v

bot = MegaPi()
bot.start()

my code

bot.motorRun(M1,0)
sleep(2)

print (“start test”)

while 1:
sleep(2)

bot.ultrasonicSensorRead(3,onRead)
print (distance)
idist = int(distance)
if idist < 12:
    print("time to turn")
