Add Python 3 Binding Generation via Pybind11 * Created entry point packet/python3_module.cc to create bluetooth_packets_python3 Python module. Layer specific packets are submodules of this top layer module * Define shim layer for Builder::Create() functions to use a std::shared_ptr instead of std::unique_ptr as Python does not support explicit ownership transfer * Add py::keep_alive to make sure the shared_ptr does not get garbage collected until the returned object is garbage collected * Redefine PacketView::Create() method as a constructor for packet view and throws value errors when packet is in valid so that users don't have to call IsValid() * Redefine Builder::Serialize() method to return a Python list of bytes directly instead of using BitInserter. Python binding users need to manually concatenate sub-sections of generated packets to form a bigger packet * Add build rules to generate and build the Python 3 library Example: >>> import bluetooth_packets_python3 as bp3 >>> write_ssp_enable_builder = bp3.hci_packets.WriteSimplePairingModeBuilder(bp3.hci_packets.Enable.ENABLED) >>> write_ssp_enable_bytes = write_ssp_enable_builder.Serialize() >>> list(map(lambda b : hex(b), write_ssp_enable_bytes)) ['0x56', '0xc', '0x1', '0x1'] >>> write_ssp_enable_pkt_view = bp3.PacketViewLittleEndian(write_ssp_enable_bytes) >>> write_ssp_enable_view = bp3.hci_packets.WriteSimplePairingModeView(bp3.hci_packets.SecurityCommandView(bp3.hci_packets.CommandPacketView(write_ssp_enable_pkt_view))) >>> write_ssp_enable_view.GetOpCode() OpCode.WRITE_SIMPLE_PAIRING_MODE >>> write_ssp_enable_view.GetSimplePairingMode() Enable.ENABLED Bug: 143374372 Test: make and run locally Change-Id: I8775c2d26a393aa5c1a417b7f845f7102fe4120e
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"
