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?
