\nI desoldered Q1 + Q2 and made a wire from collector to emitter (both Q1/Q2). That directly routes the control signals to Reset/GPIO0. \n\nNow it is working ok. No more timing issues - I could even wait for 1sec between the 2 instructions.
Text Notes 12300 3300 0    60   ~ 0
The circuit is an XOR, and it exists for compatibility between the ESP8266 and the Arduino IDE Serial Monitor.\n\nIf you hold GPIO0 low while RST is low, it puts the ESP8266 in bootloader mode instead of just restarting the firmware. When communicating through a Serial connection, the ESP8266 uses GPIO0 as the RTS signal for flow control.\n\nThe Arduino IDE uses both the DTR and RTS signals to reset a chip and launch the bootloader, but its standard signals would put the ESP8266 into flash programming mode instead of just resetting the serial interface.\n\nThe XOR allows the Serial connection to use RTS for flow control while the regular firmware is running, but prevents GPIO0 from being held low during reset.
