    Hello and sorry for the late reply.
    If you use the DPS310 only, it would omit the Sensor Hub Nano and the HC-05 bluetooth module. You would have to connect the sensor via i2c directly to the MKR1000, and once you are able to access the temperature, pressure and altitude values from the DPS310, change those in the getSensorValues() function in the code. The rest will be the same and it should work.
    I haven't gotten the time to do this modification, but if you do it, please inform me and I will update the documentation.
    Thanks for asking.

    I just hope the staring is in a good way 😂

    Thanks a lot!

    It is enabled in the code. You just have to set the Eventor widget in the Blynk app to send 1 to V3 when its the time for medication. This will be done through the eventor widget itself. Let me know how it goes

    Is the HC-05 in AT mode when you try to connect?
    Make sure your phones bluetooth is off when you connect the Sensor Hub Nano to the the bluetooth module and vice versa.
    Are you using the same bluetooth module? A picture of your setup could help
    I also had this sometimes but simply unplugging everything and trying again fixed it. Turn the Sensor Hub Nano off and then on after sometime.

    When I saw the screenshots just now, it appears the same ("IFX_NANOHUB") in my phone too :)
    Anyways, the Sensor Hub Nano is connected to the HC-05. So what you do is download a bluetooth terminal for your phone, and pair the Sensor Hub with it. Make sure that the bluetooth module is powered off (when its on, it automatically attempts to connect to the specified MAC address). Set the baud rate to 115200 (just configure as you configured the HC-05), and then send this to the Sensor Hub through your phone once its paired:
    $info id=
    It should return something like:
    And you know what to do with the name.
    Let me know if you have any issues.
    EDIT: But I doubt the name will differ, should be the same

    Thanks for trying out my project.
    Looks like the Sensor Hub Nano is not connected properly to the bluetooth module. This could be an issue in your wiring (Confirm that first), or could be an issue with configuration of the HC-05 bluetooth module (Setting the baud rate to 115200,etc). AT mode is only for configuration of the bluetooth module and is done only once (Upload the AT commands sketch and configure). And when you connect to the Sensor Hub Nano, just turn off the bluetooth module to exit AT mode (The Sensor Hub Nano wont work when it is in AT mode).
    Read the above information and try it again. Hopefully it should work.
    EDIT: Or you could just try and connect the Sensor Hub Nano with your Android phone and check its name. Should be "IFX_NanoHub". Just confirm that and tell me.

    This depends on what you want to use it for. The fall detection and all depends on the DPS310 barometric air pressure sensor, which is present on the Sensor Hub Nano. If you could interface the DPS310 to work directly with the Arduino MKR1000, you would be eliminating the need for the Sensor Hub Nano as well as the HC-05 bluetooth module (This is one of my future improvements for this project), that would be good, but you will need to modify the code and all.

    I have been thinking about this. My plan was to use a GPS module (For tracking its location outdoors), and a GSM module for internet connectivity outdoors. But I don't have the modules at the moment. Maybe once I have them...

    Well, this depends on the stage of the disease the patient is in, if it is advanced, then the patient wouldn't know what it is beeping for. In that case, anyone wouldn't want to keep such a patient alone with any device. But the beeping would certainly help the caretaker. The main functions, which could help a lot is the fall detection (and location using a GPS chip).
    As for the ESP32, I simply didn't use that because I had the MKR1000 at hand and ordering one would take time. That could be used as well with the proper code. Using the ESP32 would just replace the Arduino MKR1000 and the HC-05 module.

    First of all, it's not a band, it's a watch. What needs to be present in the watch is the MKR1000, the bluetooth module, a display, the Sensor Hub Nano, a button switch, a buzzer. and the wireless receiver. All of these are pretty small, and can easily be included in a watch if you remove the pin headers and solder wires directly (those were just for prototyping on a breadboard)
    Other than that, you should read the "How it works" section, you have a wrong idea of its working. A bluetooth module is used to get the Sensor Hub connect directly with the MKR1000. There is no i2c communication between them. And also, I haven't used the DPS310 alone, but I still see no reason why it won't work with the MKR1000, it's just a matter of the proper code.
    As for the working, why don't you build it yourself and tell me? (Just look at the screenshots, if you don't have the parts!) :)
    Edit: I haven't completed the documentation yet, hopefully I'll do it by the deadline. Why don't you read it once its done?
