Overview of the project and work

ochikov

Hello Everybody,

 

I will post my overview of the project. I managed to do a lot of work that is described there. I still wait RF modules and Ethernet Shield. Since then I managed to connect all the sensors to one Arduino Uno and start making tests with monitoring. As I receive the other stuff that I have purchased, i will start making tests with controlling the feeding system. I still have problems with calibration of Rain Sensor. But soon I will have success. Bellows are pictures:

 

This is the solution overview. As soon as I managed to understand and learn the kit's that we have, I will change the arduinos and use the kits to send/receive data and controlling the system.image

  • Looks good Ognyan. I like the infographic of the system overview. Lots of easy to read information.

     

    I have to ask, what are you using to read the sensor-puck? I purchased a Plugable brand BLE and couldn't get it to work correctly on anything. Including Linux, Win 10, Win 8 or Win 7. I don't mean with the puck, I mean at all. I have since found out from their site that there are known issues. And I have since returned the device.

     

    Now I'm looking at purchasing one of the SiLabs/Bluegiga BLE112. I think it may be more suited to work with the SiLabs Sensor-Puck. Especially since it is the one referenced in the source code I received from SiLabs tech support. Which you re more than welcome to if you would like to take a look at it.

     

    Also, if you need any further help with getting started on the software from the SiLabs MCUs I'll do what I can. image

     

    Cheers,

    Rick

    Hello Rick,

    Thank you for the good work. Now I use the Android app to read from Sensor-Puck. I try through the EFM32 ZERO GECKO Platform to program the Sensor-Puck, but with no success. Bellow is a picture from my Nexus 5. You can see the readings. I wish to find a way to use the RF kit because it has built in energy monitor and etc. Where I can plug in additional sensors to collect data and then send it through the 868 Mhz Kit? As soon as I managed to do this, I will throw away arduino stuff.

    But, I think it matters which Bluetooth device you use. Take a look at the Bluegiga ble112. That's the device that SiLabs mentions in their source code for the puck logger. And Bluegiga is an SiLabs comapny.

    Totally agree with you, Rick! I was sponsored by Bluegiga on several Bluetooth Projects and these are probably the better devices on the market for usability, documentation and adaptability.

    Good to hear this from you Enrico.

     

    I tried using a Pluggable BLE dongle and couldn't get it to work at all on any OS. The BG device is a little more expensive, but I think it's a much better device for this application. Now, I have to get one in-hand so I can see if I'm correct. image

    Hi Rick,

     

    take a look to this (old) video.

    This was the first prototype based on WT12 from Bluegiga. The proof of concept is that the BT Bluetooth series (BLE was not yet on the road) includes its own microcontroller to program the bluetooth chip and when not in program mode is used as part of the same Bluetooth features. So, with an arduino connected to a PC it was possible to enter in the Bluetooth chip in terminal mode via the Arduino, send commands and then Arduino was able to use the Bluetooth device to work in this way. This means a sort of shape-shifter device where depending on the conditions of input sensors the BlueGiga Bluetooth was programmed to manage a specific kind of protocol, from OTA to data transfer, audio layer and so on.

     

     

    P.S. I am not a super-expert of Bluetooth and BLE applications (last year I worked hard on BLE but the client has imposed the Nordic hardware) bus as a member of the Bluetooth.org SIG (Special Interest Group) by some year I had and have access to documentation that is almost difficult to find in other ways.

    Nice video Enrico! Man, there's nothing like a handful of parts and a piece of perf board.

     

    "depending on the conditions of input sensors the BlueGiga Bluetooth was programmed to manage a specific kind of protocol, from OTA to data transfer," Assuming here OTA is Over-TheAir programming? Nice!

     

    OK now! You're claiming to be a BLE expert is just going to get you a bunch of questions when I get my BG BLE dongle. lol...

     

    First Question... BLE112 or BLE113? The 113 has a smaller footprint and lower power consumption. Do you think it will work well with the sensor-puck?

     

    See, told ya. Lots of questions coming your way. image
