esp sdk have light sleep and modemsleep option for ap connected power save.
i measured 1-2ma in light sleep but its not stable. its changing . 1-2ma to 40ma for connected ap.

In a way I did. Using nodemcu lua firmware rather than the naked SDK. It made a significant improvement to connect time. However, I find that establishing a connection to the AP is a lengthy process by itself.

#18996 For me, using nodemcu lua fw, I get these timings. 'wake' is timer at the very start, 'network' when status 5 reached.
Code: Select all                         wake  network
512KB module (-01, -07)  0.29s 1s
  4MB module (-201)      0.29s 3s
  4MB module (-12)       0.6s  3.3s

The esp-201 is unusual in having a fast flash(*) but slow WiFi connection.

cheers

(*) slow flash shows as slow wakeup and very slow file access. One esp-12 was fast until a fw flash when it became slow, I still do not know what changed this but I assume some parameter or autodetect.
