ESP8266 Community Forum

- Sun Jan 11, 2015 7:18 am #6983 i have purchased esp8266 board. This module reply only two commands.
When i send AT module reply OK and WHEN i send AT+GMR module reply firmware version.
When i send AT+RST module reply ERROR and also reply ERROR to all command except above two.
Please tell me what is the problem...

- Sun Jan 11, 2015 12:26 pm #7001 Are you sending upper case commands at all times? The firmware will only allow lower case for a few AT commands.

- Sun Jan 11, 2015 2:33 pm #7011 I send all commands in upper case.

- Mon Jan 12, 2015 1:42 am #7044 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
