Sorry that your AT firmware is not provided by our company, we do not have command AT+IPR.

Would you like to have a try with our latest AT firmware ? http://bbs.espressif.com/viewtopic.php?f=46&p=5964#p5964

Please download the bin files into flash through ESP Flash Download Tool. http://bbs.espressif.com/viewtopic.php?f=57&t=433

When I switch the baud rate down to 9600 using AT+IPR=9600, it works IF I don't turn off the ESP. If I turn it off then it forgets all my firmware and I have to flash it again.

This is what I get at 76800 baud:

Code:

 ets Jan  8 2013,rst cause:2, boot mode:(3,6)

load 0x40100000, len 25968, room 16
tail 0
chksum 0x0c
load 0x3ffe8000, len 2092, room 8
tail 4
chksum 0x6f
load 0x3ffe8830, len 9360, room 4
tail 12
chksum 0x45
csum 0x45
jq+PW*5hY*)Dr
S.


Any suggestions? This only happens when I change my baud rate. I am not forgetting to change my baud rate in my serial monitor either so that's not the problem.
