I'm searching for an app, zip or xposed module that can read the actual battery levels of a bluetooth peripheral, just like the iPhone.
I have thoroughly researched on the subject and found out that if the Bluetooth headset sends battery level status in correct format, then you have a chance to read battery level in lollipop. But as most of the headsets are built to send data for just iPhone, I hate to admit that those headsets battery level won't be readable in android. So here is my question, can we change the way android reads the data, like it would understand data sent for iPhone, or is there an app to see what Bluetooth is sending like a decoder or converter app for Bluetooth signals.
People have suggested me this app.

It's just a timer and far from accurate. I NEED SOMETING THAT READS ACTUAL DATA RECIEVED FROM THE BLUETOOTH HEADSET.
I have seen this happening in an LG G4 and some Xiaomi Phones so this is quite possible to port into an app too. I know this might not work with all headsets so I have some really good expensive headsets that are able to show battery information. Thank you.
