Hi, I have the MAXI POWER and I’m trying to communicate with my PC via a UART Transceiver named KYL-210. I can’t seem to either send or receive data to the controllino.
The transceivers work well(using the model and these specific transceivers for a while) and I also tried switching the RX and TX multiple times to make sure I didn’t mess it up. I also switched between the serials (tried the main serial and serial1).
I wasn’t using any libraries like SoftwareSerial, simply wrote Serial.begin(9600) and Serial.println(“a”) or Serial.write(“a”).
