Hi Friends.

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.

The 0020000903 version is pretty old, this is why the AT+CIOBAUD command doesn't work, it was not existing at that time. You should flash your module with newer firmware.

Hi,could you please send me the new firmware and any android app that controls the module esp-01

set wifi settings using at command and then use "AT+CIUPDATE ", it will update to latest firmware automatically.
