*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.
−

−
==Features==
 
−
* Bluetooth 4.0 low energy compliant, Bluetooth low energy certified
 
−
* Supporting “AT” commands to configure UART rate, device role (master, slave), name and password
 
−
* Using HM-10 integrate BLE module with TI CC2540 chip
 
−
* Using the U-Shape 27-pin interface (UPin-27), the standard interface of Microduino
 
−
* Delivered ready to plug in.
 
−
* 2.54mm (0.1 inch) pin pitch, compatible to bread board and hole board
 
  
 +
===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)
