This tool provides functionalities to automatically extract and parse BT Snoop logs from a Bluetooth bugreport.
Select a specific analyzer using the corresponding subcommand. Supported analyzers are listed below.
usage: bugreport.py a2dp [-h] [options] path
Extract A2DP profile information
positional arguments:
path path to the bugreport file
options:
-h, --help show this help message and exit
--signal-lcid SIGNAL_LCID
override the signaling channel LCID
--signal-rcid SIGNAL_RCID
override the signaling channel RCID
--stream-cid STREAM_CID
override the stream CID
--codec-type CODEC_TYPE
override the codec type
--sampling-frequency SAMPLING_FREQUENCY
override the sampling frequency
The A2DP analyzer will parse AVDTP signaling exchanges for each connection, and automatically extract, plot and decode the audio stream when it is available (i.e. not offloaded).
As a requirement, ffmpeg needs to be installed on the host machine. ldac is not natively supported by ffmpeg, but libldacdec may be used to decode the extracted stream:
git clone https://github.com/hegdi/libldacdec.git make -C libldacdec cd libldacdec && ./ldacdec stream_LDAC_*.bt
