Joystick to pan&tilt raspberry pi camera (python)

Need Help With My Project
1

So, my setup is as following:
ESP32 with joystick running micropython + blynk
Raspberry pi running python + blynk

What I want to do:
Use the joystick to control the pan&tilt movement of the camera

What I have managed to do:

With as slider connected to a virtual pin, i can use the app on my android phone to control the pan&tilt movement of the camera. This is pretty simple and straightforward, when I move the slider the value gets passed to the raspberry pi and it updates the pan/tilt

What I can’t seem to do:

I want the joystick to update the pan&tilt of the raspberry pi. I can use the same virtual pin (use the same token even though I’m using two devices, I don’t think bridge exists for python). When I move the joystick, the value on the slider updates, but this new value is not passed on to the raspberry pi.
Is there a command to automatically update the value from the joystick to the raspberry pi? Otherwise I think I could make the raspberry pi do a virtual sync, but I am afraid to flood the server?

Any other way to do this?

Thank you very much!

Show your Python code for both ESP32 and RPi

The camera :

import BlynkLib
import time
import pantilthat

BLYNK_AUTH = 'ABC'

blynk = BlynkLib.Blynk(BLYNK_AUTH)

@blynk.VIRTUAL_WRITE(20)
def v20_write_handler(value):
    #print(value)
    value = str(value)
    value = value.replace("[u'","")
    value = value.replace("']","")
    value = int(value)
    pantilthat.pan(value)
    print(value)


while True:
    blynk.run()
    time.sleep(0.1)
    blynk.sync_virtual(20)

The joystick:

from m5stack import *
from m5ui import *
import units
import BlynkLib

clear_bg(0x000000)
joystick0 = units.Joystick(units.PORTA)

BLYNK_AUTH = 'ABC'
blynk = BlynkLib.Blynk(BLYNK_AUTH)

circle0 = M5Circle(160, 120, 15, 0xFFFFFF, 0xFFFFFF)

from numbers import Number

X = None
Y = None
i = None



X = 0
Y = 0
while True:
  blynk.run()
  blynk.virtual_write(20,X)
  circle0.setPosition(x=X)
  circle0.setPosition(y=Y)
  if (joystick0.X) > 160:
    if X > -90:
        X = (X if isinstance(X, Number) else 0) + -5
       
  if (joystick0.X) < 80:
      if X < 90:
          X = (X if isinstance(X, Number) else 0) + 5

  wait(0.1)

(I have to replace the sleeps with a function that gets called every X seconds

Try to move the code outside the loop so you’re left with blynk.run() only.
