Double check that the correct GPIO pin number is used. After upload, the GPIO0 - GND connection has to be removed and the module must be power-cycled to execute the firmware, since the autoreset doesn’t exist in hardware for that module.
DUDE! That’s right- and wow is the LED Builtin bright.
It is blinking. Gotta pull that wire.
Thanks Hommes.
That’s where the button on GPIO0 as shown in a link above would come in handy. Only pressed during uploading, unaffecting otherwise.
