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 ?

rudi can you send me yours bin files? I still have now working at all ... I made connection to UART1 with no results ...

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:

you do not need any more USB Adapter or others.
simple flash over the usb cable ( uart0 )
simple monitor over the usb cable ( uart0 )
