Here are sequentially screenshots of the IDE when connected to the board.

Maybe the problem is in the IDE settings or in the drivers? I am using windows 8.1.

What happens if you try hitting enter in the IDE a couple of times?

Nothing happens

Do you get a new prompt (the > character)?

No

Or what happens if you type 1+2 and hit enter?

Input is blocked in IDE. Below the inscription: CONNECTED TO COM8 (NO RESPONSE FROM BOARD)

The firmware is uploaded without problems. But the board doesn't connect to IDE ...

I use git bash for Windows.

cd "D:\Espruino"

git clone https://github.com/espressif/esptool

cd "D:\Espruino\firmware"

python "../esptool/esptool.py" --port COM8 erase_flash

python "../esptool/esptool.py" --port COM8 --baud 115200 write_flash --flash_freq 80m --flash_mode qio --flash_size 32m 0x0000 boot_v1.6.bin 0x1000 espruino_esp8266_user1.bin 0x3FC000 esp_init_data_default.bin 0x3FE000 blank.bin

What kind of ESP8266 board do you have?

NodeMCU v2 or v3 - I'm not exactly sure which version.

What happens if you press reset on the ESP8266 while the IDE is
connected?

The error is the same..

Connected to COM8 (No response from board)

Hi All! Need help.

Espruino IDE (Native) espruino_ide_win64_0v72.1
Firmware ESP8266 2v08

IDE Error:

I set in the IDE-COMMUNICATIONS-Baud Rate = 115200 !

There is a connection via the COM-terminal, but the IDE does not want to connect! What is the problem?
