如果其他任何尝试连接的应用程序需要断开连接，我们如何才能使BLE外围设备仅连接到我们的Android应用程序（中央）

Question

As question suggested we have our own BLE device and Android app to connect with that device. We are able to connect with BLE device and do all operations successfully.

In the meantime, we are able to detect our BLE device with other 3rd party apps and able to connect and do operations.

But we want to restrict the other apps to connect with our BLE device and if they connect with device immediately it needs to disconnect. I have searched in google and SO but unable to get any information to achieve this, if any one have idea help me out

Answer 1

on connect event send some data from app to the device and get verified data from device to app, change some programmed mechanism that app send some data to device and device verify and gives acknowledgement and based on that you keep connections or else you can disconnect from the device. I had implemented this things and working perfectly

public boolean connectDeviceBonded(String address, String name) {
        if (address == null) {
            throw new NullPointerException("Address cannot be null or not found");
        }
        macAddress = address;


        boolean value =  bluetoothLe.connectScannerBonded(address);
        if ( value) {
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            int ret = reqEncryptedKey(10000);
            if (ret != SUCCESS){
                return false;
            }
        }
        return value;
    }

reqEncryptedKey() send some encrypted data to device and device has same encryption algorithm and device verify my data and gives response to app the success and fail, based on success and fail app can keep connection and disconnect. and I also put some piece of code in device so that if device is giving fail then device disconnects automatically.
