ESPeasy starts as ESP_D328D4 with password

[everwake]

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-01 is running with a dhcp server and has the IP of 192.168.4.1, if I point my browser to that IP I get a login link, no password I tried worked.

tried reflashing the module, reflashing work, but the result is always the same, any idea what´s up?

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 happens

tried esptool.exe -p com3 erase_flash - did not work.

pulled esptool.py from github, ran esbtool.py --port com3 erase_flash, module flashed a couple of times, reset it and loaded the firmware again, same shit.

also tried shorting RX+TX, does nothing.

Any ideas on what to do?

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...

Hello ... try to enter the "Reset" command via the Arduino serial monitor or another RS232 terminal.
Then the entire content of memory is erased and the device get into factory default ...

Memory formating process is visible in the terminal window and internal LED blinking and took about 40-60 seconds depending the size of flash.

Try to flash blank.bin to:
0x00000, 0x01000, 0x40000, 0x7c000, 0x7e000
or blank512/1024/4096.bin to
0x00000

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, now we have ESP_0 back
I connect to ESP_0, configure my wireless settings, and in my AP I can see "newdevice" connecting and getting an IP.

I try to surf to the IP to complete the configuration, but it is not responding.
all of a sudden I notice the AP ESP_0 comming online again, I connect to it and surf to 192.168.4.1/setup, and I am back att the "wifi setup wizard"

it seems it did not save the settings even though it successfully connected to wifi?

I have repeated the steps above many times,by removing it from the AP and starting over, the problem is consistent.

I am using ESPeasy 78, is there another version that I should be using? or did the flashing brick my ESP module?

Edit: took a new module I never used (ESP-01 1MB black board version) and loaded ESPeasy on it, it never started the AP, blue LED was on constantly and nothing happened
just to make sure there is nothing wrong with the modules or my ftdi interface I loaded nodemcu firmware, worked without issue.

edit 2: flashing the modules with ESPeasy again and connecting to the serial port gets me this:

Fatal exception (0):
epc1=0x400ef278, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000
Fatal exception (0):

Fatal exception (0):

which just scrolls eternally

has anyone been able to load firmware version 78 on a ESP-01, I have tried two different modules, failed both times even though the module and serial interface are fine

I wonder if your powersupply is adequate.
It must be a 3.3V 500mA preferrable.
And do not forget to include some capacitors very close to your ESP module.

Look her for tips about your powersupply http://www.esp8266.nu/index.php/Power

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 setup nodemcu using the same board and same serial interface, without any power issue

will try and report back

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 sometimes not...

thanks a lot for the suggestion, since I obviously did not think about that...

Not stupid i think, the problem is it sometimes works, and sometimes not.
Sets you on the wrong foot.

I use now standard an powered USB Hub for the Wemos and NodeMCU.
My USB3 connection on my computer also has enough power.
All my other ESP modules always use a separate power supply, not the FTDI 3.3v for the serial connection
