Usage

Device Dump/Clear

Usage: java -jar bodybuggbypass.jar

The program writes all retrieved data to a file named: {timestamp of last data retrieval}.log

Once all data has been read, the device's memory is cleared and internal time as well as data retrieval times are set to the current date/time.

Dump Parser

Building the parser requires golang. Steps to build are as follows:

go get github.com/bemasher/errhandler
go build parser.go

Usage: parser [INFILE] [[OUTFILE]]

Parameters:

• INFILE is required.
• OUTFILE is optional and defaults to "data.json"

The input file is parsed and written as a json encoding to OUTFILE. The basic structure of the file is a list of the following object:

Session {
	Channel string
	Epoch int64
	Divisor uint32
	Payload []arbitrary
}

• Channel represents the channel name of the session.
• Epoch is the unix timestamp of the time the first data point was recorded.
• Divisor is used for determining the time interval between records, 1 divisor = 1/32 sec.
• Payload is a homogeneous list of any of the following types:
  • uint16
  • int64
  • {Timestamp int64, I int, J int}

Caveats

To avoid the same fate as the FreeTheBugg project, I am not packaging any of the jars this program depends on which belong to BodyMedia. Instead you'll need to download and place them in the directory bodybuggbypass_lib which must be in the same directory as the executable jar bodybuggbypass.jar:

• armband-applets-1.11.0-SNAPSHOT.jar
• common-applets-1.11.0-SNAPSHOT.jar
• common-shared-1.11.0-SNAPSHOT.jar

Information

Sample dump and parsed data are found in sample.log and sample.json.
