Blynk.delay() function

@Fettkeewl if your code is well designed there shouldn’t be any need for yield() but you will see it from time to time. You will also see delay(1) and it is acceptable up to perhaps 200 but ideally no higher, above this then SimpleTimer (or Photon equivalent etc) is recommended.

What count’s as “well designed”, is it the amount of time it takes to perform a loop? Keeping it as low as possible?
If there is no need to call yield() with a well designed code, just out of curiosity, when does an “auto-yield” occur?

The ESP handles any pending events each time the loop() function completes, OR when delay() is called.

I wonder if we can put equal sign between “well designed” and “fluent program flow”

I read a detailed article on GitHub some months ago about the ESP’s WDT but I’m struggling to find it.

Having searched I believe the contributor was possibly @pasko-zh and he / she has an open pull request for updates to the ESP8266 Arduino readme.md including this graphical presentation

The full details of the pull request are at https://github.com/esp8266/Arduino/pull/2533/files
Useful WDT information, although not that easy to follow in a pull request.

Hi , I am using a ESP 32 and a ultrasonic sensor to activate a doll if some one comes near by. I also would like to activate from Iphone and Google Home. The doll activation needs a delay function between the activation and sensing due to mechanical stability. Blynk gets disconnected with the delay. I understand why. I am using python for the whole project. Do we have a code to incorporate delay function while stay connected with the Blynk. Once sensed or activated through blynk, I need about 2 mins of delay before the next activation. That is the time doll takes to come back to rest. If there is no sensing , the void loop can be run without delay. The issue comes when there is a sensing and the doll need to be activated.
