If vTaskDelay is called,will esp32 enters the modem sleep state during vTaskdelay's period?

Modem sleep should work when radio is not needed regardless of whether task is paused. What type of context the actual switching in/out of modem sleep uses is another question, probably interrupt + preempt. For light sleep, that should occur when task is paused assuming other conditions ok but I don't think it is implemented yet.

Based on a conversation in another thread, I don't think, I know. The best you can realistically hope for right now is idle-sleep of the CPU cores with vTaskDelay(s) or putting the whole SoC under Deep Sleep (which has it's own drawbacks).

While the chip's quite capable of long-endurance battery operations, the IDF (and probably every other RTOS built...and there's several now...) isn't there yet- because they're still getting base functionality fully up.
