Hi sorry for my english, I have a Heltec Wireless Stick and I use the Modbus Master library. When I define the “node.begin(1, Serial2);” with Serial2 I can read data normally but when it is with Serial “node.begin(1, Serial);” I get very strange characters. I need to receive by Serial because my PCB is already done. I am using the pinout from the official Heltec page.
