I have 2 Arduino Nano that will communicate in half duplex mode with transcievertransceiver using MAX485. But the master has libraries like Wire.h, uses tone() and also recievesreceives UART communication.

I'm a beginner and I'm a little bit confused regarding serial communication. I read when using SoftwareSerial inrerruptsinterrupts called by some libraries can mess up SoftwareSerial's timer and it will not interpret incoming bytes correctly.

3 bytes are sendsent when something changes/max. every 200ms200 ms. So not a lot of data and at baud 9600 baud. Will it cause any problems when running RS485 on SoftwareSerial + together with DFPlayer? (DFPlayer's TX is disconnected)

Also, when it becomesdoes become a problémproblem using SoftwareSerial?
