How to access _async_service_task_handle to suspend?

[me-no-dev]

did you pull the latest code? vTaskDelay is no longer in the async task. You also should keep in mind that there are other threads involved, like the wifi and LwIP threads. Suspending the task is not a very good option, because packets might arrive and get discarded (if the event queue is overflown). Please pull the latest AsyncTCP and WebServer and see how it goes

Thanks, I pulled the latest code for AsyncTCP and ESPAsyncWebServer. I'm not too worried about getting packets discarded, as like I said I need my project to switch to a mode that ONLY reads an ADC over SPI and writes that data out serial and/or a WiFiClient (not async).

I see that the delay was taken out, which I think basically means that the Async Library will take over full control of Core1. While this is probably fine for most people who are using these libraries as they aren't even using both cores, but I have a need to control the tasks very rigidly. Basically when the user initiates "high speed mode", I really do want to shut off the Web Server entirely, as there is no reason for them to want to access a webpage at this point and I don't want to devote any resources to this.
Would you suggest I simply use the the Webserver library (https://github.com/espressif/arduino-esp32/tree/master/libraries/WebServer) so I can decide when to process "server.handleClient();"? As I know you wrote that library as well. Or is there an issue to simply not processing "server.handleClient();" at all for a while?

the delay is missing but the task is made to wait for packet as long as it needs to, so instead of waiting 2ms, it might wait a minute or more if there is no packet coming, and not wait 2ms if there is one pending.

Is there any reason why I shouldn't change the "xTaskCreatePinnedToCore" to "xTaskCreate", and give it a lower priority, such, the same priority as my "housekeeping" task?
