Re: ESP-01 hangs and resets itself without AT+RST command

Hi,

boot mode : can use "AT+CIUPDATE" command to upgrade AT firmware through WiFi, your Flash size needs to be 1MBytes or larger.
non-boot mode: can NOT use "AT+CIUPDATE" command to upgrade AT firmware through WiFi, for 512KBytes Flash.

Use Espressif official Flash Download Tool, it will detect the size of your Flash while downloading and show it in "DETECTED INFO" area.

Thanks for your interest in ESP8266 !

Hi,

The "readme.txt" is with the AT bin files.

You need to download the latest AT v0.50, and unzip it, you can find the "readme.txt" in it.

Thanks for your interest in ESP8266 !

ESP-01 hangs and resets itself without AT+RST command

2015-11-25T21:52:31+08:00

hello dear forum,

I upgraded my ESP-01 to version “0020000903”

I try to make webserver application - ( I succeeded , I was able to see my webpage at google chrome )

everything is fine however after 5 minutes standby

ESP doesnot receive ethernet packets from Google Chrome anymore

when I ping it from PC the packets are lost

and when I tried to give AT command it suddenly resetted itself

why is that so ?

thank you
