Are you sending upper case commands at all times? The firmware will only allow lower case for a few AT commands.

I send all commands in upper case.

What’s the version info that you get by command “AT+GMR” ？
Maybe you could download the official AT firmware and try it again。。http://bbs.espressif.com/viewtopic.php?f=21&t=93
