UART baud rate
Hello,
I read the AT instruction set and examples and it states the maximum baudrate for the UART is 5000000 baud. Is that a limitation of the hardware or are higher baudrates also possible.

Hello underwater,
it is the limitation of AT command firmware. You can get a higher baudrate if you write the code by yourself

Hi ,
What is the maximum limit for baudrate, when configuring through code??
Thanks
R.

Re: UART baud rate
So, you mean, 655360 bits per second??
Re: UART baud rate
I have tested with 4000000,3500000,3000000,2500000, 2000000 bits/sec on ESP32-WROVER-KIT (with FTDI USBtoSERIAL) and it works.

Re: UART baud rate
I mean 5000000bit/s, in the data format of start+8bit+stop, it can trans 500,000 byte/s.
Do you test with 5000000 bits/sec ?
wookooho
Re: UART baud rate
No, I havn't tested it yet.

Re: UART baud rate
you said your own code what does that means ?? im trying to send at-commands using usb-uart to esp32 at 2000000 but unable to communicate..

Re: UART baud rate
Hello, have you tested using the ESP-IFD Sdk simply set the baud rate to 4000000? Are necessary some special operation to set this value of baud rate? thank you
