ESP-01 no Accesspoint after Flashing

[Barb232]

Hello,

flashed an ESP-01 and another ESP-13 with the newest R78-Firmware (512k). Flashing with Esp-Flasher was ok, but after a reboot there are no accesspoints to log in.
Other ESP-Moduls like NodeMCU are ok.
Thank you for your great work.

two days ago something similar was discussed here:

Thank you for your quick help.
I installed the easyESP system on my PC (i usually work with mac). I installed a esp8266 2.1rc from the library and i got something strange.
The esp8266-01 got flashed but i see only a few seconds the AP, then the blue led lights off. then on for a time and so on. i thought off the current. so i tried a different power supply and the same problem. its look that the esp makes a reboot. i tried with two different 01.

What is the output/ messages from the serial Monitor?

[Barb232]

Very very strange,
if i am starting this with arduino Serial monitor it works! I have an accesspoint ESP_0
if i am starting this with an powersupply i haven't a AP.
Here my log

hmmm? to small power supply?
check again? change with another? everthing properly grounded?
hmmm, dont know more...

[Gorgo]

if i am starting this with arduino Serial monitor it works! I have an accesspoint ESP_0
if i am starting this with an powersupply i haven't a AP.

Do you mean powering ESP from the USB-to-serial?
Are you using a breadboard?
What is the max. output (Amps) of your PSU?

[Barb232]

Hi,
it finally works, i had several issues:
Problem Power-Supply: it took more current than i expected
Problem GPIO 0 connection: Maybe i set the startup to LOW so i got the startup into flash mode.

BTW: i used the switch feature in the software. Wouldn't it be nice to select a "Button" feature? .. Fields: active high -> low , low -> high, Time to H-L <> L-H in mseconds
Because i used this esp-01 in my diffusor (LEDS and diffusor on) and there is a button not a switch.
