Hi everyone,
We are using esp32 in our project, when wifi is connected from esp32 the other tasks are working slowly, can anyone please tell me the solution for this.
Thank you

Can you move the other tasks to a different core?

It is worth checking the power supply to it is good as I have known them to do all sorts of weird things if they are not happy with the power.

Any chance of you being able to show what exactly you're doing aside from WiFi?

Power section is good, we have sufficient power required for the microcontroller and there is no noise also.

Can you tell us what order size the slowdown is of? If you need the absolute full speed of the controller, WiFi may slow you down a bit as the stack is fairly large and might push your ADC code out of the cache at times.

Again, can you expand a little bit more? How much and what type of slowdown are you seeing? What are you doing with the ADC in the first place? We can't help you if you don't give us any information.
