Metric: Add logging for link layer connection events * Logs when there is an event affecting Bluetooth device's link layer connection. Triggerred when there is a related HCI command or event * Users of this metrics can deduce Bluetooth device's connection state from these events * HCI commands are logged before the command is sent, after receiving, command status, and after receiving command complete event comes back * HCI events are logged when they arrive * Simplifies logic in btu_hcif_hdl_command_status() since p_cmd is never null and we always ignore parameter total length field * Call btm_identity_addr_to_random_pseudo() when parsing command status packet for LE create connection, extended create connection, add/remove/clear whitelist commands DETAILS: * Bluetooth classic commands: - CMD_CREATE_CONNECTION - CMD_DISCONNECT - CMD_CREATE_CONNECTION_CANCEL - CMD_ACCEPT_CONNECTION_REQUEST - CMD_REJECT_CONNECTION_REQUEST - CMD_SETUP_ESCO_CONNECTION - CMD_ACCEPT_ESCO_CONNECTION - CMD_REJECT_ESCO_CONNECTION - CMD_ENH_SETUP_ESCO_CONNECTION - CMD_ENH_ACCEPT_ESCO_CONNECTION * Bluetooth low energy commands: - CMD_BLE_CREATE_LL_CONN [Only logged when there is an error or initiator filter policy is 0x00] - CMD_BLE_CREATE_CONN_CANCEL [Only logged when there is an error] - CMD_BLE_EXTENDED_CREATE_CONNECTION [Only logged on error or when initiator filter policy is 0x00] - CMD_BLE_CLEAR_WHITE_LIST - CMD_BLE_ADD_WHITE_LIST - CMD_BLE_REMOVE_WHITE_LIST * Bluetooth classic events: - EVT_CONNECTION_COMP - EVT_CONNECTION_REQUEST - EVT_DISCONNECTION_COMP - EVT_ESCO_CONNECTION_COMP - EVT_ESCO_CONNECTION_CHANGED * Bluetooth low energy meta events: - BLE_EVT_CONN_COMPLETE_EVT - BLE_EVT_ENHANCED_CONN_COMPLETE_EVT Bug: 112969790 Test: make and test drive statsd Change-Id: Ib843dfa95bb6448c41dac261dabcf17947efda06
Just build AOSP - Fluoride is there by default.
Instructions for Ubuntu, tested on 14.04 with Clang 3.5.0 and 16.10 with Clang 3.8.0
mkdir ~/fluoride cd ~/fluoride git clone https://android.googlesource.com/platform/system/bt
Install dependencies (require sudo access):
cd ~/fluoride/bt build/install_deps.sh
Then fetch third party dependencies:
cd ~/fluoride/bt mkdir third_party cd third_party git clone https://github.com/google/googletest.git git clone https://android.googlesource.com/platform/external/aac git clone https://android.googlesource.com/platform/external/libchrome git clone https://android.googlesource.com/platform/external/libldac git clone https://android.googlesource.com/platform/external/modp_b64 git clone https://android.googlesource.com/platform/external/tinyxml2
And third party dependencies of third party dependencies:
cd fluoride/bt/third_party/libchrome/base/third_party mkdir valgrind cd valgrind curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/valgrind.h?format=TEXT | base64 -d > valgrind.h curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/memcheck.h?format=TEXT | base64 -d > memcheck.h
NOTE: If system/bt is checked out under AOSP, then create symbolic links instead of downloading sources
cd system/bt mkdir third_party cd third_party ln -s ../../../external/aac aac ln -s ../../../external/libchrome libchrome ln -s ../../../external/libldac libldac ln -s ../../../external/modp_b64 modp_b64 ln -s ../../../external/tinyxml2 tinyxml2 ln -s ../../../external/googletest googletest
cd ~/fluoride/bt gn gen out/Default
cd ~/fluoride/bt ninja -C out/Default all
This will build all targets (the shared library, executables, tests, etc) and put them in out/Default. To build an individual target, replace "all" with the target of your choice, e.g. ninja -C out/Default net_test_osi
.
cd ~/fluoride/bt/out/Default LD_LIBRARY_PATH=./ ./bluetoothtbd -create-ipc-socket=fluoride
Follows the Chromium project Eclipse Setup Instructions until "Optional: Building inside Eclipse" section (don't do that section, we will set it up differently)
Generate Eclipse settings:
cd system/bt gn gen --ide=eclipse out/Default
In Eclipse, do File->Import->C/C++->C/C++ Project Settings, choose the XML location under system/bt/out/Default
Right click on the project. Go to Preferences->C/C++ Build->Builder Settings. Uncheck "Use default build command", but instead using "ninja -C out/Default"
Goto Behaviour tab, change clean command to "-t clean"
