Re: ble scan and wifi connection in the same time

During the boot procedure, it will fetch data from the SPIFFS in NVS, and then continue to run the entire program by using this data. The program itself doesn't perform any modif...

aws cert storage location

Hi, is it possible to store the aws cert in nvs instead of sd card or code embedded?
I want to update the cert of the device but it doesn't have sd card.

Re: keep variable after restart

Hi Ivan,

it seems RTC_DATA_ATTR will lose after software reset.

In fact, I am working on this to resolve the problem of wifi turn on/off and then RTC IO case deep sleep current increase which I raised in github issue, is there any update on this issue?

Re: keep variable after restart

yes, I did. below is my simple code. If I use part A, variable test will increment every 4 second. However, if I comment out PART A, and use the esp_deep_sleep, the test variable become a strange value and won't increment. that means deep sleep wake up cleared the test variable? static RTC_NOINIT_AT...
