Using NUCLEOWB55G to communicate with RS485 device

[odianosen_o]

I saw in the stm32 datasheet that the chip has a means of communicating/controlling RS485 devices. However, there’s not enough information to figure out how to connect a differential pair of wires in hardware to the nucleo directly from a rs485 device to establish communication.

Other alternatives I’ve seen are using UART with an external module to convert UART signals from nucleo to RS485 channel. Is this the only option?

Hello @odianosen_o

The only way to connect an RS485 to the NUCLEO-WB55RG is using an external module as you said.

Best Regards.
