ESP8266_NONOS_SDK-2.2.0,How to achieve sleep and button wake up

[315002181huang]

As mentioned, what I need to achieve is that ESP2866 can also wake up through GPIO at the same time.Whether only scheduled wake up and GPIO wake up can only be implemented in one way.
Wifi_fpm_do_sleep (0xFFFFFFF);wifi_enable_gpio_wakeup(GPIO_ID_PIN(4), GPIO_PIN_INTR_LOLEVEL);", you can go to sleep.When the button is pressed, the current changes from 0.92mA to 67mA, indicating that it has been awakened, but no action can be performed.
Therefore, after sending data to the cloud platform, how to wake up the chip after pressing four buttons and continue to send data to the cloud platform after connecting WiFi?

How about RTOS SDK? There is an example of power save, not sure if it can help. https://github.com/espressif/ESP8266_RT ... power_save

I'm back after a nice long needed vacation, I'm still chunking away in college for the next 3 years.
I am unsure if I understand your questions correctly but I'll give this one a go.

If I understand your questions correctly you want to act on a button press (or multiple on waking).
If you can provide a step by step example of what you are looking for I can indeed help

Here are some pieces anyways.

The first Snippet is how to read and write a counter to your SPI memory, this will survive any powerloss/reboot you have.
The second goes in your startup / main code that detects the reason for booting, Upon botting read the SPI, then sleep for about a second or so, As your pressing the button you can inc the SPI index value to +1 then after your sleep cycle on boot act on it or another method.

I personally use the following method below to have the chip detect that its in a crashing loop then to kick off a debug safe mode to report in if that were to ever happen so I have a chance for recover with FOTA.

I hope this points you in the correct direction, if not Ill be back this week and will watch for your reply.
