-This is a tool to generate classic Bluetooth traffic with specified period and package size.
-Together with the SvcMonitor, which will be called automatically in this android service, can be
-used to measure the CPU usage from the Java layer Bluetooth code and the underlying system service
-com.android.bluetooth.
-
-1. Server (Listener) - Client (Sender) model. Both run as an Android service.
-2. No pairing needed. Communicate via unsecured RFcomm. Client establishes the connection by
-providing the MAC addr of the server.
-3. Bluetooth has to be turned on on both side.
-4. Client can configure the traffic by specifying the transfer period and package size.
-5. A separate monitor process will be automatically forked and will be reading from /proc file
-system to calculate the cpu usage. The measurement is updated once per second.
-6. The monitor process (com.google.android.experimental.svcmonitor/.ScvMonitor) can be run as an
-independent service to measure cpu usage on any similarly configured tests (e.g. wifi, BLE). Refer
-to SvcMonitor's README for usage and details.
-
-Usage:
-To instal the test:
-On both the server and client device, install the 2 apk:
-$ adb install $OUT/system/app/bttraffic/bttraffic.apk
-$ adb install $OUT/system/app/svcmonitor/svcmonitor.apk
-
-To start the service on the SERVER side:
-$ adb shell am startservice -a start --ez ack true \
-com.google.android.experimental.bttraffic/.BTtraffic
-
-To start the service on the CLIENT side:
-$ adb shell am startservice -a start \
--e addr "F8:A9:D0:A8:74:8E" --ei size 1000 --ei period 15 \
-com.google.android.experimental.bttraffic/.BTtraffic
-
-To stop the test:
-On either the server or client:
-$ adb shell am startservice -a stop \
-com.google.android.experimental.bttraffic/.BTtraffic
-
-To look at the data:
-$ adb logcat | grep bttraffic
-
-Options:
--e addr: MAC addr of the server, in uppercase letter.
---ei size: package size, unit: byte; default: 1024, MAX: 20MB
---ei period: system sleep time between sending each package, unit: ms, default: 5000
-                  ** if -1 is provided, client will only send the package once.
---ez ack: whether acknowledge is required (true/false)

-This Android service measures CPU usage of a program and an underlying system service it relies on.
-An example of this would be an android app XYZ communicates to some other device via Bluetooth. The
-SvcMonitor service can monitor the CPU usage of XYZ and com.android.bluetooth.
-
-Usage:
-
-To start the service:
-$ adb shell am startservice -a start \
--e java XYZ -e hal com.android.bluetooth \
-com.google.android.experimental.svcmonitor/.SvcMonitor
-
-To stop the service:
-$ adb shell am startservice -a stop \
-com.google.android.experimental.svcmonitor/.SvcMonitor
-
-To stop the service config:
-$ adb shell am startservice -a change \
--e java NewName -e hal NewService \
-com.google.android.experimental.svcmonitor/.SvcMonitor
-
-To monitor the data:
-$ adb logcat | grep XYZ
-
-Options:
--e java NameOfProgram: any running process’s name.
--e hal NameOfSysService: name of the system service the previous process relies on.
---ei period: period between each measurement (frequency). Unit: ms, Default:1000, Min: 100
