On Arduino Nano IoT 33, with the current FW only BLE is available, but, following the instructions on this forum's thread https://forum.arduino.cc/index.php?topic=654631.0, especially post #15 (and parts of post #6, plus linked webpages contained in it), I verified the possibility to have BT classical (and BLE), by flashing the ESP32 chip. The flashing made WiFi unusable though, but after updating the chip's FW to the latest FW, everything was like before.
I would propose that classic BT is added to the driver, given that I verified that it can work, so that classic BT, BLE, and WiFi will be supported at the same time, giving to the IoT 33 the full range of capabilities offered by the ESP32 chip.
