Smarter Life Challenge - The Henrietta Project

dougw

The Henrietta Project is a smart thermostat system entered in the PSoC4 Pioneer Kit Smarter Life Challenge.

An introductory video that describes the system features and costs has been uploaded.

There will be a second video to demonstrate the system.

Current status is all subsystems are connected, configured, compiled and working with appropriate test software.

The system will be cleaned up mechanically and electrically before finalizing the demo software.

Current status is:

  • all PCBs are designed, assembled and tested
  • all subsystems are connected, configured, compiled and working with appropriate test software.
  • graphics editing software for the LCD displays is programmed and working, and graphics have been completed
  • the touch pad is fully mapped and working
  • Bluetooth communications are working with both android and PC hosts
  • the environmental interface is tested and working
  • the servo motor and door switch are tested and working
  • the temperature and light sensor are tested and working
  • the GPS clock is tested and working
  • the PC app is complete and tested
  • voice control was demonstrated
  • the thermostat schedule editor has been added to the firmware

 

Not shown are remote Bluetooth devices - I use an android device for remote monitoring and control (Galaxy Note)

The GPS module is used to provide an extremely accurate time and date clock that never needs to be set.

Here is a diagram of all subsystems and how they are connected.

    It sounds like it is going into AT mode (slow blinking) but not recognizing AT commands. This could be due to the commands being sent at the wrong baud rate or the commands not ending with carriage-return and line-feed characters.

    You could try different baud rates - 9600 is pretty common.

    Hi Doug,

     

    Thanks for the reply! I have tried that approach. It seems that the module gets into some special mode - I have a different LED pattern. So far I have the following: when the module is in transfer mode but not peered, the blinking pattern is short ON, short OFF. When in peering mode the pattern is 2 short ON, long OFF. Now when the Key is up (3.3V at start-up), it is long ON, long OFF. Interesting is that I can no longer connect to the module, through phone or other Bluetooth module. So right now I am trying to get the response from the module back to the PSoC4 and from there to PC terminal (I am using Hyperterminal). I will keep you posted on my progress. Any thoughts on it will be greatly appreciable.

     

    Thanks again,

    Stoyan

    Hi Stoyan,

    I did not change the settings on my Bluetooth modules, but this is the procedure as I understand it:

    Step 1: With everything powered off and no active Bluetooth devices nearby, connect PIN34 (the KEY pin) to a 3.3 Volt power supply PIN which is still off.

    Step 2: Supply power to the module (PIN34 is also supplied with high level since the PIN34 is connected with power supply PIN). Then the module will enter to AT mode with the led blinking slowly.

    At this time, the baud rate is 38400.

    Step 3: Send AT commands at 30400 Baud - note that all commands must end with CR LF. (0x0D 0x0A)

    Have you tried this?

    Doug

  • Hi Doug,

     

    It is a neat design indeed.

    I am trying to use the same Bluetooth module as you (actually the module is JY-MCU V1.05, and recognized as HC-05), and so far I have managed to create a small program, so I can successfully transfer strings and chars over it. I have a challenge with the AT commands for it though. I am trying to change the baud rate, pin and name of the unit, but I can not make it respond to me. It seems that is not getting into the command mode, so I am trying many different approaches and so far no luck. Any help will be greatly appreciable.

     

    Thanks,

    Stoyan

    Hi DAB,

    I expect to post more details as I figure out how. This is my first blog, first on-line video, first C program, first PSoC project and the amount I don't know far exceeds what I do know. It is a fantastic thing that the PSoC development eco system has so many resources, but there is a lot of complexity under it all. The "100 projects" were very useful, although I haven't been able to actually run any of the examples. Fortunately my own project is running well and I'm learning a lot. I think I just figured out how to move the blog into the right area. Hopefully I can figure out how to link the video to the blog ...
