Bluetooth speed downgrades: Repeated wake lock release; aborting release: bluedroid_timer #609

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Build a bluetooth socket between mobile and Glass
2. Transfer a lot of  large chunks of data (images) between mobile and Glass
3. Look at the logcat.

What is the expected output? What do you see instead?
Before the update of XE20.1, there was no error message and the transferring 
speed was on average 300KB/s.
Now the logcat gives me tons of error messages: "10-03 12:52:10.507: 
E/BluetoothAdapterService(1113393744)(1047): Repeated wake lock release; 
aborting release: bluedroid_timer". And the transferring speed is jumping from 
10KB/s to 100KB/s.
So I'm curious about what does this message actually mean? Is there any changes 
regarding the bluetooth device?

What version of the product are you using? On what operating system?
Google Glass with XE20.1

Please provide any additional information below.
I'm testing using the same code as Issues 485:

I see a lot of this while working with roximity, blue tooth proximity senseors. 
These two lines repeat many times.
