Cannot communicate with another android device.

[AlphaRosh]

Hello, I'm attempting to connect and communicate with two Android smartphones.

For testing, I'm using a Vivo V20 Pro and a Samsung Galaxy Tab (SMT515). Both are running the sample serial app.

To duplicate:

1. Launch the app on both your phone and your tablet, and enable Bluetooth and location services on both.

2. Making one gadget discoverable and searching for it from another. (I am able to obtain the device and pair it.)

3. With both phone or tab, go to "Connect to paired device to chat" and select the device to chat.

When I try to chat with the connected device after connecting to it from vs, I receive the following exception

Exception has occurred.

BluetoothConnection newConnection =
await BluetoothConnection.toAddress(device.address);
i have passed a raw device's address in the above code still it is not able to connect to that device
were you able to connect to your desired device?
