I have the web server code up and running, and getting responses from it. But, I can't get any response from AT commands, nor I can get any info in ESplorer (heap, chip info, chip id, etc). ESP8266 ESP01 is connected through FTDI and to 3.3V LDO regulator connected to USB 5v. I have two ESP01 boards that behave exactly the same. Firmware flash with nodemcu flasher works fine as well.

The code is from this page:

Never mind, it was the firmware. I didn't know that flashing the code in Arduino ide overwrites firmware too. When I flash AT firmware it works with AT again. So I guess I can't have both.

If you upload any other firmware, the AT firmware is gone/erased, so don't expect any AT command to work anymore.
