Can ESP8266 be connected to Access Point during deep sleep?

[helpme]

Deep sleep (<10uA) is very impressive. May I ask whether ESP8266 can remain connected to the Access Point even in deep sleep?

The ESP-Wroom module datasheet has the following line;
- Wake up and transmit packets in < 2ms

Does it mean that the modue can wake up from deep sleep and starting sending out packets through the Access Point within 2ms?

Hi,
As I know, from deep sleep it wake up with a real reset, so all data are lost and need a new AP connection.

Dear Sir,

About sleep function description, you can refer to "9B-ESP8266__Sleep__Function Description" for details.

For deep sleep, chip will disconnect all Wi-Fi connection and data connection and only the RTC module is still working, responsible for the timing of the chip wake-up. In this mode, the Wi-Fi works in extremely low power consumption.

If your needs to maintain the connection with AP in sleep, you can consider the light sleep mode.

Any more questions, please let us know.

Thanks.
