ESP_ wireless network after flash my ESP8266

#1 Post by weado » 03 Sep 2018, 22:54

Hello everybody,

I installed EASYESP on a NodeMCU and I tried it with some devices. But, I would like to try an other project withour EASYESP, but it's impossible to erase correctly my NodeMCU, because, I put a simple sketch on my board, but I always a network, beginning by ESP_ and finish by the end of MAC Address (WifiManager I think of EASYESP).
I tried to erase and flash all memory, with ESP8266 DOWNLOAD TOOLS and blink_1M, and put my a simple code and my wireless network show up again and again...

Do you have some tips to help me to erase correctly my board ? I like Easyesp, but for the simple code, it's not necessary ;-)

Thanks

A NodeMCU has 4MB of flash, so you should flash a 4MB blank image first.
This must be done via the USB serial port ofcourse.

Ok I will this evening to flash with a blink image of 4M. Do you have it or where can I find it ?
My board is a NodeMCU (like Wemos D1 Mini) with a micro USB and I flash it with its. Is it incorrect to do like that ? Do I use a FTDI USB serial ?

Thanks a lot

Regarding flash, you're doing it right. The Wemos got a serial to USB converter/programmer onboard.

Hey,

So, I flashed my NodeMCU with the blink_4M.bin instead of the 1M file, in bootloader mode, but I always have my SSID "ESP_xxxxx" from my board.

I don't what I am doing to erase completly my board ... :cry:
