It might be configured to UART1 pins 16 & 17

hi
only a thinking, have not tested just in time ( later time )
can we use uart0 as AT command port, too ?
does it be enough to set it in the sdkconfig ?

best wishes

hi
can you not compile too?
will prepair this next step.

checkt this steps:

- ? gnd connect between the esp32 modul and the "terminal usb adapter/uart1 brigde"
- ? Rx, Tx not swapped
- ? CR+LF at and of AT Command
- ? after boot, the log is on UART0, the ready for AT Command comes on UART1
..

fyi:
why you connect to the pins of modul and not to the pinheader 16,17, GND?
have a look:

tested with DevKitC and FTDI 232 ( bridge the uart1 out for AT Commands..)
