I was working with esp8266 (WROOM-02 module) for a few months, and 2 or 3 weeks ago, I find an issue that I couldn´t revolve yet.
I´m working with AT Firmware. The last order of WROOM-02 came from factory with 1.3.0 firmware version, and it is not valid for me, beacuse I need AT+CIPSNTPTIME command, and it is not available on 1.3.0.
So I´m trying to update with AT+CIUPDATE command and i´m getting crazy, beacuase it doesn´t works, and I don´t know why...
I have tried to update with "virgin" factory modules, with 1.3.0, and also with another modules with 1.5.0 flashed by me, but the result is exactly the same.
I hope anybody could help me, because I don´t know what to do. Thanks.
This is the loop:
Code: Select all

AT+RESTORE
