With the ESP32-Arduino, I learned that we can exchange data with USB-CDC just as we do with a physical UART port, using the same functions as with a physical UART port, such as Serial.print() and Serial.read().

Thank you for reply.
I will try to send a question to the email address you wrote.

In Japan, We can use only TFPD05H08750011 used for obtain MIC certification.
I'm planning to sales Wi-Fi / Bluetooth antenna for ESP-WROOM-32U and WROVER-I.
Could you additional certification for my new antenna by I paying an additional fee to Espressif?
