We came across a scenario where we were to communicate with a Raspberry Pi using Bluetooth. For this, we needed to implement a full-duplex type connection with the RPI.
We looked for some quick solutions over the internet, but unfortunately, we found none. There were very few Bluetooth based libraries that were well written and almost none/very few had an implementation for creating Bluetooth server sockets.
That's when we decided to come up with a simple and elegant approach to our problem.
bluetoothadapter is a package which enables a Flutter application to communicate with other devices/programs through Bluetooth. It does so using Bluetooth based server sockets, which allows the Flutter app to establish a full-duplex connection with the other Bluetooth based devices which act as its counterpart.
Features provided by bluetoothadapter
We start by adding the following dependency to our
dependencies: bluetoothadapter: <latest version>
There are mainly 4 main steps involved in the process:
Here's a code sample for the same:

I hope that this solution is what you require to enable your apps to communicate through bluetooth for critical functions and this implementation will help you understand how to use
