(I am quite suire) not caused by the slow data transfer, but must be something else in the stack. I set multiple coils, read two registers and read multiple inputs. Each access takes about 400ms (estimatedd). I set the timeout to 200ms. I am using modbus on the RS485 bus. I...

我决定使用NodeMCU,因为它已经实现了一个WiFi接口,而且非常便宜。但是,我已经意识到我与电网分析器的通信会有问题,因为它有一个RS485接口,并且实现了Modbus协议。RS485接口没有问题,因为我将使用一个用于UART的适配器,但我未能找到用于MicroPython的Modbus库。所以问题是,Pymodbus与MicroPython兼容吗?
