- Sat Jun 06, 2015 3:41 pm #19678 Hello Guys,

im very new in the tiny ESP 8266 World, and i have not the "big electronic skills".

But i was able to connect the ESP to my PC with an FTDI Adapter, after that i flashed the latest NodeMCU firmware. Next i connected to the ESP with the ESPlorer IDE with an Baudrate of 9600.

I can create scripts, can run them all fine. But when i disconnect the USB Serial Adapter and reconnect it i can not connect anymore to the ESP.

I dont know what i should do? It seems like the firmware flash was only "temporary"

sounds to me as if you forgot to disable flash mode. The pin is checked on hard boots to decide if starting firmware
or entering boot mode. After flashing the firmware seems to started via some soft boot that does not check this.

Hope that helps,
Cal

how can i disable the flash mode? I mean my procedure is the following:
Flashing -> ESPlorer -> Creating an init.lua (Creating a Hotspot)

After that i disconnect the ESP from the FTDI Adapter and connect the ESP to an Breadboard.
But the Hotspot does not show in the WLAN List.

Im setting :
CH_PD to HIGH, GPIO0 to HIGH and GPIO2 to HIGH

Have i forgotten something?
