      Try the following:

      edit the crontab

      pi@raspberrypi:~ $ crontab -e
      no crontab for pi - using an empty one

      Select an editor. To change later, run 'select-editor'.

      1. /bin/ed
      2. /bin/nano <---- easiest
      3. /usr/bin/vim.tiny

      Choose 1-3 [2]: 2
      Go to the end of the file and add the following command. Do not forget to modify the path to match your installation directory.

      @reboot java -jar /home/pi/server-0.23.0.jar -dataFolder /home/pi/Blynk &

        That’s the one I followed and still not auto loading. Will have another go tonight

        UIFlow, so easy an adult can learn it!
        If I don't know it, be patient!
        I've ether not learned it or am too drunk to remember it!

        M5Black, Go, Stick, Core2, and so much more it cant be fit in here!

            Hi! I'm a complete beginner learning to use stickC, I managed to figure out Blynk with Arduino, but now, I'd like to do it with uiflow.
            Since I have the latest versions of both (blynk.py - 0.2.6 & uiflow - 1.4.5.1), I wanted to know if the procedure is still the same. Also, if there are other reference links/good material to learn about esp32 with python, then do share!
            I'm an industrial design student trying to make a battery-powered heated lunchbox for my thesis, which I'd like to control with the phone and also show nice graphics using stickC.
            Any help appreciated!
            Thank you :)

              Alright!
              I figured how to upload and run the BlynkLib 0.2.0 on uiflow - 1.4.5. :D
              The device is successfully detected and shown running on the android app.
              Now, I only need to figure how to control/toggle GPIO pins through uiflow with Blynk. :)

              Any tips? :P

              P.S.
              The push notification is not working. Is this limited to M5Stack only? Or also possible on my device...

                I haven’t worked with Blynk in a while, so I can’t comment on gpio control. If you end up getting something working, please share it.

                I’ll see if I can find time to test push notifications on the m5stickC.

                    I was thinking if it was possible to insert the received virtual value from Blynk button here (orange block), one could toggle the GPIO pin.

                    P.S. The push notifications work perfectly! Didn't add the notification widget. (silly me!)

                    Now I just need to figure out to toggle GPIO through virtual values from the button.
