SOLVED : Unable to change baud rate
Posted: Thu Dec 04, 2014 3:41 pm
Just flashed my ESP-01 to latest firmware binarys.
AT+GMR gives me 0020000903
When I try to change the baud rate with AT+CIOBAUD=9600 I get ERROR.
AT+CIOBAUD? also gives ERROR.
What am I doing wrong?

COR, that info is well hidden!!
It would be nice if Espressif updated the AT Instruction Set document.
I can confirm that AT+IPR=9600 changed my baud rate.
Both AT+IPR? and AT+IPR=? gave an ERROR message.
My thanks to garyservin for pointing me in the right direction.
For anyone looking for the ESP8266 AT Instruction Set I found it in the document folder of this download :-http://bbs.espressif.com/download/file.php?id=84

For changing the baudrate permanently you can use this command:
AT+ UART_DEF=<baudrate>,<databits>,<stopbits>,<parity>,<flow control>
For example 9600 baudrate / 8 data bits / 1 stop bits and none parity and flow control
the command AT+CIOBAUD=9600 it would change the baudrate temporarily
