I'm developing a project with PIC18F4620 and ESP01. I used a level shifter for to convert from 3.3v to 5v (TX ESP01). So, updated firmware for 0.20.

When i send the command AT+GMR, i have the results:

+GMR
0020000903
OK

So, i'm trying change the baudrate from 115200 to 9600 because this baurate is not works fine with PIC18F. Sometimes i receive the response and sometimes not receive.

The problem is that i can´t change de baudrate. All the time that i send the command AT+CIOBAUD:9600 or AT+CIOBAUD=9600 OR AT+BAUD=9600 or AT+BAUD:9600, just get error in response. The command AT+CIOBAUD? is not works too.

I already tried to update for several firmware versions and not works.

I know that module have any problems and not works fine.

I need help.

Thanks friends.

Best Regards.

Paulo
