Serial communication requirements

  • Default serial configuration：
    • Baud rate: 9600
    • No check
    • Data bits: 8
    • Stop bit: 1
  • As for Arduino IDE serial monitor：
    • Set at："No line terminator"、"9600baud"
  • For other serial debug software：
    • Baud rate: 9600
    • No check
    • Data bits: 8
    • Stop bit: 1
  • We suggest using Microduino-Core32u4 to debug this BT module:
    • Microduino-Core32u4 module can use the USB to simulate the serial 0, and BT uses the 32u4's serial 1 (RX0,TX1), so you don't need to change the existing jumper (RX0,TX1) and it won't impact program download or the serial port's function.
  • Microduino Shield BT4.0 uses the default serial RX0,TX1 to communicate with Core module, so it can be directly connected with Microduino FT232.

Use PC to debug

  • When debugging directly through the serial port：
    • No need to stack the FT232 directly, and just cross connect the FT232 and BT4.0's RX0,TX1.

Use FT232R、Core to download and debug

  • If it keeps using the default jumper (RX0、TX1)：
    • Unplug the Microduino Shield BT4.0 during downloading the program;
  • If you want to change the jumper cables to meet your requirement, you need to cut the connection between two intermediate of the pad and RX0/TX1, and then connect them to D2, D3(or D9、D10).
    • If it needs to change the jumper, you can change the serial connection of Microduino Shield BT4.0 and Microduino Core from "TX-RX0、RX-TX1" to:
      • TX-D2、RX-D3 (For Core+'s Serial1)
      • TX-D9、RX-D10 (you can adopt SoftwareSeria libray to solve the problem)
