About my Project

Hi Nordc Technical support team;

My name is Ercan. I'm from Turkey. I am a Master degree student in Electronics and Communication Engineering department.I want to make a graduation project and I want to do this project on Bluetooth 5.2.The project I want to do will be as follows.
First of all, I want to design a bluetoothaccess control system.I want to trigger a relay from the output of any microcontroller or SoC cards that you use, without any handshake operation.
I will make an application for this system and in this application I will buy bluetooth rights with money and I want to switch without any handshake operation.
Which SoC card should I use for this?
Could you please share if there is a tutorial or video to support me in this regard?

Best Regards,

Thank you.

  • Hi,

    So, after activating the bluetooth feature on the mobile phone, I want to send data without not connecting to the bluetooth of the SoC card.

    For example,
    I want to transfer data to bluetooth device when I shake my mobile phone or I can use any button to pair the bluetooth module (SoC card) with my mobile phone and send data.
    In fact, the only action the user will do should be turning on the bluetooth feature.

    Thanks,

  • That's not the way Bluetooth works. You need to connect in order to exchange data.

    I think you need to spend some time researching the basics of how Bluetooth (specifically, BLE) works.

  • Hi,

    First of all thank you very much for your support.

    I want to take advantage of the Bluetooth baecon or broadcast feature.
    In fact, when I activate the bluetooth feature from the application I made, when I approach my bluetooth module, I want to send data to my bluetooth module by sending a baecon or broadcast from my phone and trigger a relay.

    I saw that this can be done when I reviewed some articles.
    I will share an article about this situation.

    BLE Technology and BLE Beacons

    What is a Bluetooth Low Energy (BLE) beacon?

    BLE beacons, as the name suggests, are beacons that communicate via Bluetooth Low Energy. Beacon devices are small radio transmitters, strategically mounted throughout locations, to broadcast low-energy Bluetooth signals in a given range. This range depends on hardware capability. On average, a beacon device can transmit BLE signals to 80 meters. This BLE signal from the beacon is capable of triggering a specific action relevant to the location.

    How is BLE technology used with beacons?

    Beacons send out an ID number via BLE channels, approximately 10 times every second. A Bluetooth-enabled device in proximity of the beacon picks up this ID number. When an app or pre-installed service like Google Nearby recognizes the ID number, it links it to an action, such as download an app or piece of content (maybe a marketing offer) stored on the cloud and displays it on the smartphone.

    Do you have any SoC card suggestions that I can do this situation? Could you suggest this to me? Could you provide me with document video support on how to program the SoC card?

    Thanks for your support.

  • A Beacon,  as the name suggests,  is send only - as the article you posted tells you.

    So you cannot exchange (ie, both receive and transmit) data with a beacon - you can only receive what it's broadcasting.

    Some phones can act as "beacons" - in which case your device would have to be a Central, scanning for the Beacon advertising. But it would still be just one-way.

    Is that what you want?

    If you want 2-way communication, you need a connection.

    nRF Chips can certainly do all this.

  • Hi,

    This is exactly what I want.I want to send a command directly from my mobile phone and trigger the relay.

    Could you send me documents?Could you send me a guide on how to do it?

    Thanks for your support.
