Finally I updated manually with serial port to latest version and works! .. this: https://github.com/espressif/esp8266_at/tree/master/bin

Looks like last cloud upgrade something was wrong.. :evil:

Code: Select all

AT+GMR
0020000903

AT+IPR=9600

AT+IPR become a new at command to change baudrate, but I don't know for ask.

Thanks!
