I tried to connect to a TCP socket the ESP01, and I can't connect when run CIPSTART

On the ESP01 downloaded the lastest firmware using the command:

Code:

esptool.py --port /dev/ttyUSB0 write_flash 0x00000 boot_v1.6.bin 0x01000 at/512+512/user1.1024.new.2.bin 0x7e000 blank.bin 0x1fe000 blank.bin


The AT Command what I use are the following:

Code:

AT


OK
AT+RST


OK
