In Python, am using the LightBlue module for Bluetooth connectivity. How do I get the speed at which I am sending file to my phone from my laptop (Ubuntu)?
You need a binding for the Bluetooth driver/OS service that handles the Bluetooth device.
Most drivers are written in C, some in C++. If you can get the source code/API or if it's provided you might be able to access it from python. You might need to code some custom binding to your OS service to do so.
Python bluetooth transfer speed?
