how many tasks can ESP32 handle?

I know this is probably an unanswerable question, but I just need a ballpark figure. Running FreeRTOS, is there a practical limit to the number of tasks I can run?

Limit is your max ram usage. Freertos doenst apply tasks limits...

Just make a loop creating tasks until it fails. I did that once but forgot how many I could make. Since then I found you could free 90K of Bt memory. So I could have created a bunch more anyway.

Just know, the more tasks you have the less time each one will get from the CPU.

Oh yeah, I'm aware of that. The benefit of more tasks is just easier programming for me. I'm using 4 now, and want to add at least one more. It just prompted my curiosity more than anything.

Well, as has been said before, it depends on the amount of memory. I just ran a quick test, creating tasks with 8K of stack (which should be more than enough for most purposes) and I could happily create 33 of 'em... so 5 shouldn't be an issue. If anything, the limiting factor mostly is the amount of (internal) RAM you use as stack, as others already said; there's no inherent limit in place.
