#90363 I tried now multiple ESP01, multiple serial converter and usb cables, but nothing works.

I've wired it like that:

Code: Select all(Left ESP) (Right Serial Converter)
RX => TX
TX => RX
CH_PD => 10k Resistor (verified) => VCC (3.3V - verified)
GPIO0 => 10k Resistor (verified) => VCC (3.3V - verified)
GND => GND
VCC => VCC


As indicated by the "verified", I've checked it indeed is outputting 3.3V on VCC and I've verified it is a 10k resistor.

I've tried to wire the CH_PD and GPIO0 directly to VCC as some other instructions show, but that didn't work either.

What am I doing wrong? it blinks for a second sometimes and then stops.

Thanks for any input!

#90374 While waiting for this to be approved, found a fix: connect the reset pin through another 10k to VCC and set the baudrate in the serial monitor to do NL&CR and 115200 baud instead of 9600.
