Quick Troubleshoot – ESP-01 not responding to AT commands

Maybe after you flash your ESP-01 with newer firmware from here, it doesn’t respond to AT command, or starts echoing what you type.


You need to change “No line ending” to “Both NL and CR”, and the baud rate to 115200.


Some commands will still return error. But after that, it should be okay.
