    3. QUICK START STAMP-PICO adopts the most streamlined circuit design, so it does not include a program download circuit. When users use it, they can download the program through a USB-TTL burner. The wiring method is shown in the figure below.

  • Page 6: Bluetooth Serial

    3.2. BLUETOOTH SERIAL Open the Arduino IDE and open the example program `File`->`Examples`->`BluetoothSerial`->`SerialToSerialBT`. Connect the device to the computer and select the corresponding port to burn. After completion, the device will automatically run Bluetooth, and the device name is `ESP32test`. At this time, use the Bluetooth serial port sending tool on the PC to realize the transparent transmission of Bluetooth serial data.
