1 # CHIP Linux Bridge Example
3 An example showing the use of CHIP on the Linux. The document will describe how
4 to build and run CHIP Linux Bridge Example on Raspberry Pi. This doc is tested
5 on **Ubuntu for Raspberry Pi Server 20.04 LTS (aarch64)** and **Ubuntu for
6 Raspberry Pi Desktop 20.10 (aarch64)**

22 $ sudo apt-get install git gcc g++ python pkg-config libssl-dev libdbus-1-dev libglib2.0-dev ninja-build python3-venv python3-dev unzip
24 - Build the example application:
26 $ cd ~/connectedhomeip/examples/bridge-app/linux
27 $ git submodule update --init
28 $ source third_party/connectedhomeip/scripts/activate.sh
32 - To delete generated executable, libraries and object files use:
34 $ cd ~/connectedhomeip/examples/bridge-app/linux

39 ## Running the Complete Example on Raspberry Pi 4
41 > If you want to test ZCL, please disable Rendezvous
43 > gn gen out/debug --args='bypass_rendezvous=true'
46 > Note that GN will set bypass_rendezvous for future builds, to enable
47 > rendezvous, re-generate using
49 > gn gen out/debug --args='chip_bypass_rendezvous=false'
53 1. A Raspberry Pi 4 board
54 2. A USB Bluetooth Dongle, Ubuntu desktop will send Bluetooth advertisement,
55 which will block CHIP from connecting via BLE. On Ubuntu server, you need
56 to install `pi-bluetooth` via APT.
57 3. Ubuntu 20.04 or newer image for ARM64 platform.
61 Follow [Building](#building) section of this document.
65 - [Optional] Plug USB Bluetooth dongle
67 - Plug USB Bluetooth dongle and find its bluetooth device number. The
68 number after `hci` is the bluetooth device number, `1` in this

84 - Run Linux Bridge Example App
86 $ cd ~/connectedhomeip/examples/bridge-app/linux
87 $ sudo out/debug/chip-bridge-app --ble-device [bluetooth device number]
88 # In this example, the device we want to use is hci1
89 $ sudo out/debug/chip-bridge-app --ble-device 1
91 - Test the device using ChipDeviceController on your laptop /
