## Introduction
The CC13XX_26XX all clusters example application provides the basis to query and
run commands for all currently implemented Matter clusters. This uses the
open-source Matter implementation and the Texas Instruments SimpleLink CC13XX
and CC26XX software development kit.
This example is enabled to build for CC1354P10 devices.
The all-clusters example is intended to serve both as a means to explore the
workings of Matter, as well as a template for creating real products based on
the Texas Instruments devices.

## Building
### Preparation
Some initial setup is necessary for preparing the build environment. This
section will need to be done when migrating to new versions of the SDK. This
guide assumes that the environment is linux based, and recommends Ubuntu 20.04.
- Download and install [SysConfig][sysconfig]. This can be done simply with
the following commands.
```
$ cd ~
$ `wget https://dr-download.ti.com/software-development/ide-configuration-compiler-or-debugger/MD-nsUM6f7Vvb/1.15.0.2826/sysconfig-1.15.0_2826-setup.run`
$ chmod +x sysconfig-1.15.0_2826-setup.run
$ ./sysconfig-1.15.0_2826-setup.run
```
- Run the bootstrap script to setup the build environment.
```
$ cd ~/connectedhomeip
$ source ./scripts/bootstrap.sh
```
### Compilation
It is necessary to activate the environment in every new shell. Then run GN and
Ninja to build the executable.
- Activate the build environment with the repository activate script.
```
$ cd ~/connectedhomeip
$ source ./scripts/activate.sh
```
- Run the build to produce a default executable. By default on Linux both the
TI SimpleLink SDK and Sysconfig are located in a `ti` folder in the user's
home directory, and you must provide the absolute path to them. For example
`/home/username/ti/sysconfig_1.15.0`. On Windows the default directory is
`C:\ti`. Take note of this install path, as it will be used in the next
step.
```
$ cd ~/connectedhomeip/examples/all-clusters-app/cc13x2x7_26x2x7
OR
$ cd ~/connectedhomeip/examples/all-clusters-minimal-app/cc13x4_26x4
$ gn gen out/debug --args="ti_sysconfig_root=\"$HOME/ti/sysconfig_1.15.0\""
$ ninja -C out/debug
```
If you would like to define arguments on the command line you may add them
to the GN call.
```
gn gen out/debug --args="ti_sysconfig_root=\"$HOME/ti/sysconfig_1.15.0\" target_defines=[\"CC13X4_26X4_ATTESTATION_CREDENTIALS=1\"]"
```
## Programming
Loading the built image onto a LaunchPad is supported through two methods;
Uniflash and Code Composer Studio (CCS). UniFlash can be used to load the image.
Code Composer Studio can be used to load the image and debug the source code.
### Code Composer Studio
Programming with CCS will allow for a full debug environment within the IDE.
This is accomplished by creating a target connection to the XDS110 debugger and
starting a project-less debug session. The CCS IDE will attempt to find the
source files on the local machine based on the debug information embedded within
the ELF. CCS may prompt you to find the source code if the image was built on
another machine or the source code is located in a different location than is
recorded within the ELF.
Download and install [Code Composer Studio][ccs].
First open CCS and create a new workspace.
Create a target connection (sometimes called the CCXML) for your target SoC and
debugger as described in the [Manual Method][ccs_manual_method] section of the
CCS User's Guide.
Next initiate a project-less debug session as described in the [Manual
Launch][ccs_manual_launch] section of the CCS User's Guide.
CCS should switch to the debug view described in the [After
Launch][ccs_after_launch] section of the User's Guide. The SoC core will likely
be disconnected and symbols will not be loaded. Connect to the core as described
in the [Debug View][ccs_debug_view] section of the User's Guide. Once the core
is connected, use the `Load` button on the toolbar to load the ELF image.
Note that the default configuration of the CCXML uses 2-wire cJTAG instead of
the full 4-wire JTAG connection to match the default jumper configuration of the
LaunchPad.
### UniFlash
Uniflash is Texas Instrument's uniform programming tool for embedded processors.
This will allow you to erase, flash, and inspect the SoC without setting up a
debugging environment.
Download and install [UniFlash][uniflash].
First open UniFlash. Debug probes connected to the computer will usually be
displayed under the Detected Devices due to the automatic device detection
feature. If your device does not show up in this view it my be disconnected, or
you may have to create a New Configuration. If you already have a CCXML for your
SoC and debug connection you can use that in the section at the bottom. Once
your device is selected, click the `Start` button within the section to launch
the session.
Select the ELF image to load on the device with the `Browse` button. This file
is placed in the `out/debug` folder by this guide and ends with the `*.out` file
extension. For OTA enabled applications, the standalone image will instead end
with the `*-bim.hex` file extension. This this is a combined image with
application and and `BIM` included. The flag to enable or disable the OTA
feature is determined by "chip_enable_ota_requestor" in the application's
args.gni file.
Finally click the `Load Image` button to load the executable image onto the
device. You should be able to see the log output over the XDS110 User UART.
Note that programming the device through JTAG sets the Halt-in-Boot flag and may
cause issues when performing a software reset. This flag can be reset by
power-cycling the LaunchPad.
## Running the Example
By default the log output will be sent to the Application/User UART. Open a
terminal emulator to that port to see the output with the following options:
| Parameter | Value |
| ------------ | -------- |
| Speed (baud) | `115200` |
| Data bits | `8` |
| Stop bits | `1` |
| Parity | `None` |
| Flow control | `None` |
## Running the Example
Once a device has been flashed with this example, it can now join and operate in
an existing Matter network. The following sections assume that a Matter network
is already active, and has at least one [OpenThread Border
Router][ot_border_router_setup].
For insight into what other components are needed to run this example, please
refer to our [Matter Getting Started Guide][matter-e2e-faq].
The steps below should be followed to commission the device onto the network and
control it once it has been commissioned.
**Step 0**
Set up the CHIP tool by following the instructions outlined in our [Matter
Getting Started Guide][matter-e2e-faq].
**Step 1**
Commission the device onto the Matter network. Run the following command on the
CHIP tool:
```
./chip-tool pairing ble-thread <nodeID - e.g. 1> hex:<complete dataset from starting the OTBR> 20202021 3840
```
Interacting with the application begins by enabling BLE advertisements and then
pairing the device into a Thread network. To provision this example onto a
Matter network, the device must be discoverable over Bluetooth LE.
On the LaunchPad, press and hold the right button, labeled `BTN-2`, for more
than 1 second. Upon release, the Bluetooth LE advertising will begin. Once the
device is fully provisioned, BLE advertising will stop.
Once the device has been successfully commissioned, you will see the following
message on the CHIP tool output:
```
[1677648218.370754][39785:39790] CHIP:CTL: Received CommissioningComplete response, errorCode=0
[1677648218.370821][39785:39790] CHIP:CTL: Successfully finished commissioning step 'SendComplete'
```
An accompanying message will be seen from the device:
```
Commissioning complete, notify platform driver to persist network credentials.
```
**Step 2**
Send commands to the all-cluster-app. Here are some example commands:
Basic
```
./chip-tool basic read <attribute-id> <destination-id> <endpoint-id-ignored-for-group-commands> e.g. ./chip-tool basic read product-id 1 0
```
Identify
```
./chip-tool identify identify <IdentifyTime> <destination-id> <endpoint-id-ignored-for-group-commands> e.g. ./chip-tool identify identify 100 1 1
```
### Provisioning
Interacting with the application begins by enabling BLE advertisements and then
pairing the device into a Thread network.
#### Bluetooth LE Advertising
To provision this example onto a Thread network, the device must be discoverable
over Bluetooth LE. BLE advertising is started by long pressing the right button
(greater than 1000ms), labeled `BTN-2` on the silkscreen. Once the device is
fully provisioned, BLE advertising will stop.
#### Bluetooth LE Rendezvous
Pairing this application with `ble-thread` can be done with any of the enabled
[CHIP Controller](../../../src/controller/README.md) applications. Use the
information printed on the console to aide in pairing the device. The controller
application can also be used to control the example app with the cluster
commands.
