ESP32 Forum

It seems that is some confusion on UART1 and UART0 of ESP32 and its function.
On the ESP32 hardware design guide,
https://goo.gl/uWVdKY it stated on Table 4:

UART0 (Pin34) U0 RXD + (Pin35) U0 TXD Used for printing logs.
UART1 (Pin25) U1 RXD + (Pin27) U1 TXD Used for receiving and sending commands.

Since UART0 is used for sending commands I believe it an error in documentation. Maybe need to switch definitions.

My question: can ESP32 UART0 (ESP32 pin34 +pin35) connected to USB for command flashing etc, and UART1(pin25+pin27) can connect to other MCU and both will work on 100% on the same time?
On this forums, I see some place that UART1 uses same buffers or driver as UART0, so UART1 can't work when UART0 is in used.

They can work at the same time.

In AT firmware UART1 is default for commands and UART0 is for debug. In user application you can do whatever you want.
