- Wed Jun 14, 2017 12:30 pm #67173 Have you tried the AT commands to set the GPIO0 and GPIO2 pins with v2.1.0 ?
I have two ESP-01 with old Ai-Thinker firmware that I am thinking about upgrading to v2.1.0.

- Thu Jun 15, 2017 3:43 pm #67223 I checked it. It works!
AT+SYSGPIODIR=0,1 //Set GPIO0 to work as an output.
AT+SYSGPIOWRITE=0,1 //Set GPIO0 to output high level

I used FLASH_DOWNLOAD_TOOLS_V3.4.8 and created by myself 8Mbit blank.bin
