boot mode and non boot mode

[Alberto]

I have searched the forum for an explanation without any success!
Could you please explain the difference? I am using AT+ commands which is the most appropriate firmware?

Thank you for the attention.

Kind regards

Hi,

boot mode : After connected to AP, ESP8266 can upgrade the AT firmware through WiFi by command "AT+CIUPDATE". This mode need the flash size to be 1MBytes or larger than that.

non-boot mode : ESP8266 can not upgrade the AT firmware through WiFi. The flash size can be 512KB.

Thanks for your interest in ESP8266 !
