but would that not cause the resistor to become a voltage divider combined with the pull up resistor that I understand is built-in to most GPIO on ESP8266 ? does unclicking the "Pull up" in tasks disable the pull-up for the GPIO? or can I use "Pin mode x Select an optional boot state ...

Hmmm....both GPIO 1 and 2 needs to be up when booting, and as far as I can read there is no pull down function on ESP-1 ?

how does one connect a normally closed switch to it?

Lets file this under "being stupid" it turns out that Costo is right, the serial interface did not have enough power to reliably boot ESP easy, it did however have enough power to boot nodeMCU. The difference? Wifi AP....it draws enough power to cause the ESP to sometimes boot, and sometim...

I am running the module off the usb-serial interface that I use for programming, and I can successfully flash different firmware. The article says to use more power than the USB - serial interface can provide once programming is done, so I will try that, but it seems odd that I could install and set...

tried flashing blank.bin to 0x00000, 0x01000, 0x40000, 0x7c000 and 0x7e000 I then flashed ESPeasy, and it was still showing the mac address in the AP name. it was however not possible to connect to that AP anymore and the blue led was constantly on. I power cycled the ESP once more, and hey presto, ...

update:

this is silly, reflashed it using nodeMCU, and then flashed it back to ESPeasy, it still comes up password protected with the mac address in the hostname...

I seems settings are preserved even when I reflash, and it also seems that no one on the entire Internet has documented how to reset settings from a windows computer I tried using the esptool.exe that is included with the ESPeasy firmware 78, but it does nothing, no matter what I input nothing happe...

I flashed ESPeasy on a ESP-01, first time it worked, but when I had configured it with a password and rebooted it no longer connected to wifi, so I reflashed it. after reflashing it comes up as a wifi hotspot with the name of "ESP_D328D4" D328D4 is the last part of the mac address the ESP-...
