AT port unresponsive

[readysteadygo2006]

Answers checklist

• I have read the documentation ESP-AT Programming Guide and the issue is not addressed there.
• I have used the latest released firmware or have updated my ESP-AT branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

AT+GMR

can not provide

ESP-AT Firmware Source

https://github.com/espressif/esp-at

Hardware Information

esp32-wroom-32

Power Supply used

USB

What is the expected behavior?

After booting the esp32 with the AT firmware, I get the standard log on the log console (UART0)
I get "ready" echoed to the AT uart (UART1)

I would expect to type a command and get a response on the at command console

What is the actual behavior?

If I type a command on the at command console, what I type gets echoed, but I get not response

More Information.

I've enabled debug, at can see debug messages of the characters I am typing on both the console and the at command console, so I'm confident that the uart is correctly configured.

Additionally, I see the same behaviour if I download the prebuilt esp-at (ESP32-WROOM-32-AT-V3.4.0.0)

I've tried using PUTTY and minicom as serial terminals

Are there any special setting required for the serial terminal?
