Hello,
To create an app with bluetooth connectivity and to share data with devices, we can customize the bluetooth APIs according to our need and then we can integrate it with our app build.
Now to measure the distance between the phone and the BLE module, we can create an algorithm which will intercept the signal received from the BLE module, analyse it based on the parameters like signal strength, emission power, receiver sensitivity. Out of the parameters will also set some constant or relative parameters based on the standard BLE to make the calculations and provide efficient results.
The technology to be used to create such an app would be Kotlin with android studio and SDKs for android and Swift with Xcode and SDKs for IOS, for the bluetooth API can be implemented in the main build file itself, and we can also create any other necessary RESTful APIs as well.
But before finalizing on anything, let’s connect in the private chat and have a brief discussion on the scope of this project, you can also share any other requirements that you might have regarding this project.
I will also share my most recent experience in this domain with you in private chat.
Thanks & Regards.
