TCP server to UART data Passthrough with ESP-AT

Hello.
Looking to replace another board acting as transparent passthrough (TCP server to uart) with ESP-32 and ESP-AT application (latest version)
The Passthorugh mode, in ESP-AT, can only be activated when single connection mode is enabled too, but the application requires that ESP32 wifi interface act as a TCP server. To enable TCP server, The connection mode must be set to multiple, that is conflicting with the Passtrough mode request.
Let's consider that I just need 1 coonection at time to the TCP server socket.
Is there any workaround or customization that could be done to the ESP-AT environment in order to reach that goal?
IS there any way to enable the TCP server in single mode?
Other ideas?

P.S. The ESP32 must also act as a Wifi Access Point.
Thank you
Best regards,
Alessandro

Your requirement is that the AT can also enter the Wi-Fi passthrough mode in the case of a single connection?

We are already implementing this function and will add it in version 2.3.0.0 of ESP32-C3. If you want to use this function in ESP32, please use the master branch to compile after ESP32-C3 version 2.3.0.0 is officially released. Please pay attention to the release of Espressif ESP32-C3 version 2.3.0.0, which will probably be released in January next year.
