Debugging

Step 1: Inside smart power plug:

• Step 2: Make sure your BT serial connection is D4, D5 by default.

Soft serial port used in program test is D4 and D5.

• • If you adopt D2 and D3
    • If adopting Core board, please change “SoftwareSerial mySerial(4, 5);” to “SoftwareSerial mySerial(2, 3);”.

• • • If adopting Core+, you need to change “mySerial” in loop to “Serial1”.

• • If using D0, D1.
    • You need to change “mySerial” in loop to “Serial” and do not stack BT while program download or it’ll cause serial conflict.

Microduino-BT

• Step 3: Build the circuit

Stack all modules needed.

• Step 4: Download test program and open it.
  • Make sure the serial port of your BT is right, which can refer to Step 2. Compile program and download after that.

• Step 5: Download Android client and then decompress and open it. It will notice users to open Bluetooth device.

• Step 6: Click “SCAN” and search for HMSoft (Old Microduino-【BT】) or Microduino (New Microduino-BT) and then connect.

• Step 7: When the status changes from “Serial Present” to “Serial Ready”, you can start communication.

Click switch button on your phone and it means a successful communication if showing “power on” or “power off” on serial monitor on PC.

Step 8: Take off USBTTL module on receiving end, fixate the socket and Microduino module and plug in, making sure offer power for the application to be controlled. Here we adopt a small humidifier.

Adjust the switch to smart control mode.
