We designed and implemented a DTU with bluetooth for Shanghai LiveSine Cooperation.

  • Designed the DTU and add a BLE to it.
  • Designed an APP which can communicate with DTU by bluetooth protocol and with the server by TCP/IP protocol (using Delphi)
  • Made sure that the communication will not be influenced by the electromagnetic field created by the strong direct current
  • Designed the communication protocol based on MODBUS protocol.
  • Interpreted the data from DTU and showed them in a friendly user interface.
  • Test in a real situation.
