Error Occur after "AT+CIUPDATE"

Postby ESP_Faye » Thu Feb 05, 2015 3:09 pm

Some users confused why something goes wrong after "AT+CIUPDATE" .

The most likely reason is that you are not using Espressif Official AT software .

Please test it with Espressif Official AT http://bbs.espressif.com/viewtopic.php?f=46&t=850.

Baudrate is 115200 , AT commands end with CR LF.

"AT+CIUPDATE" succeed or not, depends on network condition. But it will never cause your module goes wrong.

With Espressif official AT, if "AT+CIUPDATE" succeed, it will restart to run the new firmware, if fail, it will just keep running the current firmware.

Thanks for your interest in ESP8266 !

Please feel free to let us know if you have any question.

Hi,

In order to upgrade, you have to download boot.bin + user1.bin + blank.bin.

Please download the corresponding bin files into Flash, according to "readme.txt" in \esp_iot_sdk\bin\at
