With the setup described about the related Stack Overflow question (Bluetooth TX → RX0, TX0 → RX1, TX1 → Bluetooth RX), I checked the signals sent by the Bluetooth device and by the Arduino's serial port 0. Not particularly memory/speed efficient, because it creates a byte array on each read, but it's easier to use than readBytes (byte b []) (see below). I’ve successfully run the stepper motor in the cycle that I planned and I can read the … · Syntax.0 the limited memory and DMA channels make it more suited for the Teensy3. Anyway this makes things really hard, because it forces me to use a physical button to avoid the first part. 2023 · serialEvent() doesn’t work on the Leonardo, Micro, or Yún.
