sorry if I am repeating an old thread, but I didn't find one with an answer that solved my issue.
I am using an ESP8266 + usbserial connected directly (without any resistor in the middle), as I saw in several tutorials at internet.
I refresh its firmware. I tried one from here, but after the refresh, it does not let me send any AT command (I am on MAC):
./esptool.py --port=/dev/cu.usbserial write_flash -fm=dio -fs=32m 0xfc000 at/esp_init_data_default.bin 0xfe000 at/blank.bin 0x00000 at/boot_v1.5.bin 0x01000 at/user1.1024.new.2.bin
I am not sure if the line above is right, but it run without errors.
I found one tutorial in portuguese, with a link to one firmware:

I refresh my ESP with the following command:
./esptool.py --port=/dev/cu.usbserial write_flash -fm=dio -fs=32m 0x00000 v0.9.2.2\ AT\ Firmware.bin
After that, I remove the pin from the ground and restart the usbserial (I did it previously every time that I wanted to get out of the update mode and go to the dev one).
I did:
AT+RST
OK

I am having two issues, first of all, if I open from any machine in the network the following link:
http://192.168.25.70:3000/?device_id=1&flow=100&time=10
It registers on my node server what I want. From the AT+ command it does not register, meaning that it didn't arrive there. Why?
My second error is that after some time suddenly I start to receive the following message and after that I can't send any AT command anymore, so I need to refresh the firmware again
