I want to connect EBB to ESP32. How can I do that?

I want to use only 24V power (2 wires).
To do that I saw 3 ways.

1) UART-TO-BLE (the best way). Connect to STM via UART to ESP32 and use in-board Orange PI BLE to connect. But I saw only a little information about USB-UART on board configuration and it requires clip two pins. Can you help me?

2) CAN - CAN_TRACIEVER - ESP32 - Classic Bluetooth. Good chose, but I need can transiever, and it will use Classic Bluetooth, so I should write driver to implement interface.

3) USB - Classic Bluetooth - the worst way in my opinion, because of slow implementation on esp32.

So, what do you think about it?
Can you help me, pls?

The issue compares UART-to-BLE, CAN, and USB connection paths between the EBB, STM, Orange Pi, and ESP32. Start by checking the board's USB-UART configuration and the requirement to connect two pins, then determine whether any approach supports 24V power over two wires. The issue does not define a specific implementation or completion test.
