Your demand: - RS485 communication and converting to wireless bluetooth - Work within 02 days - Based on previous work If you use a full-duplex RS-485, the block diagram is simple: <RS485> <---> <Bluetooth> If your use a half-duplex RS-485, the block diagram like <RS485> <---> <MCU> <---> <Bluetooth> MCU maybe your previous work. And <Bluetooth> maybe simple as HC-06 module
