Pica is a virtual UWB Controller implementing the FiRa UCI specification. It has been designed for testing UWB ranging capabilities. Pica supports the following features:
$> git clone https://github.com/google/pica.git $> cd pica/ $> cargo run
You should receive the following output:
Pica: Listening on: 7000 Pica: Web server started on http://0.0.0.0:3000
You can now open the web interface at http://0.0.0.0:3000
and the HTTP commands documentation at http://0.0.0.0:3000/openapi
. The scene should be empty and look like this:
A command line tool is available to trigger some action such as creating an anchor. Run pica in a terminal then open a new one and do:
$> cd pica/ $> python3 scripts/console.py
If you hit Enter
, the console will list you all the available commands:
device_reset Reset the UWBS. get_device_info Retrieve the device information like (UCI version and other vendor specific info). get_caps_info Get the capability of the UWBS. session_init Initialize the session session_deinit Deinitialize the session session_set_app_config set APP Configuration Parameters for the requested UWB session. session_get_app_config retrieve the current APP Configuration Parameters of the requested UWB session. session_get_count Retrieve number of UWB sessions in the UWBS. session_get_state Query the current state of the UWB session. range_start start a UWB session. range_stop Stop a UWB session. get_ranging_count Get the number of times ranging has been attempted during the ranging session.. pica_create_anchor Create a Pica anchor pica_destroy_anchor Destroy a Pica anchor pica_get_state Return the internal Pica state pica_init_uci_device Initialize an uci device pica_set_position Set the position of a Device
If you wish to create a virtual anchor:
$> cd pica/ && python3 scripts/console.py # If the console is not started yet $> --> pica_create_anchor 00:00 # pica_create_anchor <mac_address> $> --> pica_create_anchor 00:01 # Create another one

Pica also implements HTTP commands, the documentation is available at http://0.0.0.0:3000/openapi
. The set of HTTP commands let the user interact with Pica amd modify its scene.
If you haven't use bluetooth_packetgen before, it is a tool from Android. You can build it and use it and build it that way:
# Build bluetooth_packetgen cd $AOSP_DIR source build/envsetup.sh lunch <target> # Use target 1 if in doubt m bluetooth_packetgen export PATH=$PATH:${AOSP_DIR}/out/host/linux-x86/bin/ # Generate the source cd $PICA_DIR bluetooth_packetgen \ --rust \ --include=src/ \ --out=src/ \ src/uci_packets.pdl
Then edit the uci_packet.rs to add clippy guards
