| ## Introduction |
| |
| The EFR32 lock example provides a baseline demonstration of a door lock control |
| device, built using Matter and the Silicon Labs gecko SDK. It can be controlled |
| by a Chip controller over an Openthread or Wifi network.. |
| |
| The EFR32 device can be commissioned over Bluetooth Low Energy where the device |
| and the Chip controller will exchange security information with the Rendez-vous |
| procedure. If using Thread, Thread Network credentials are then provided to the |
| EFR32 device which will then join the Thread network. |
| |
| If the LCD is enabled, the LCD on the Silabs WSTK shows a QR Code containing the |
| needed commissioning information for the BLE connection and starting the |
| Rendez-vous procedure. |
| |
| The lighting 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 |
| Silicon Labs platform. |

| |
| <a name="flashing"></a> |
| |
| ## Flashing the Application |
| |
| - On the command line: |
| |
| ``` |
| $ cd ~/connectedhomeip/examples/lock-app/efr32 |
| $ python3 out/debug/chip-efr32-lock-example.flash.py |
| ``` |
| |
| - Or with the Ozone debugger, just load the .out file. |
| |
| <a name="view-logging"></a> |
| |
| ## Viewing Logging Output |
| |
| The example application is built to use the SEGGER Real Time Transfer (RTT) |
| facility for log output. RTT is a feature built-in to the J-Link Interface MCU |
| on the WSTK development board. It allows bi-directional communication with an |
| embedded application without the need for a dedicated UART. |
| |
| Using the RTT facility requires downloading and installing the _SEGGER J-Link |
| Software and Documentation Pack_ |
| ([web site](https://www.segger.com/downloads/jlink#J-LinkSoftwareAndDocumentationPack)). |
| |
| Alternatively, SEGGER Ozone J-Link debugger can be used to view RTT logs too |
| after flashing the .out file. |
| |
| - Download the J-Link installer by navigating to the appropriate URL and |
| agreeing to the license agreement. |
| |
| - [JLink_Linux_x86_64.deb](https://www.segger.com/downloads/jlink/JLink_Linux_x86_64.deb) |
| - [JLink_MacOSX.pkg](https://www.segger.com/downloads/jlink/JLink_MacOSX.pkg) |
| |
| * Install the J-Link software |
| |
| ``` |
| $ cd ~/Downloads |
| $ sudo dpkg -i JLink_Linux_V*_x86_64.deb |
| ``` |
| |
| * In Linux, grant the logged in user the ability to talk to the development |
| hardware via the linux tty device (/dev/ttyACMx) by adding them to the |
| dialout group. |
| |
| ``` |
| $ sudo usermod -a -G dialout ${USER} |
| ``` |
| |
| Once the above is complete, log output can be viewed using the JLinkExe tool in |
| combination with JLinkRTTClient as follows: |
| |
| - Run the JLinkExe tool with arguments to autoconnect to the WSTK board: |
| |
| For MG12 use: |
| |
| ``` |
| $ JLinkExe -device EFR32MG12PXXXF1024 -if JTAG -speed 4000 -autoconnect 1 |
| ``` |
| |
| For MG21 use: |
| |
| ``` |
| $ JLinkExe -device EFR32MG21AXXXF1024 -if SWD -speed 4000 -autoconnect 1 |
| ``` |
| |
| - In a second terminal, run the JLinkRTTClient to view logs: |
| |
| ``` |
| $ JLinkRTTClient |
| ``` |
| |
| <a name="running-complete-example"></a> |
| |
| ## Running the Complete Example |
| |
| - It is assumed here that you already have an OpenThread border router |
| configured and running. If not see the following guide |
| [Openthread_border_router](https://github.com/project-chip/connectedhomeip/blob/master/docs/guides/openthread_border_router_pi.md) |
| for more information on how to setup a border router on a raspberryPi. |
| |
| Take note that the RCP code is available directly through |
| [Simplicity Studio 5](https://www.silabs.com/products/development-tools/software/simplicity-studio/simplicity-studio-5) |
| under File->New->Project Wizard->Examples->Thread : ot-rcp |
| |
| - User interface : **LCD** The LCD on Silabs WSTK shows a QR Code. This QR |
| Code is be scanned by the CHIP Tool app For the Rendez-vous procedure over |
| BLE |
| |
| * On devices that do not have or support the LCD Display like the BRD4166A Thunderboard Sense 2, |
| a URL can be found in the RTT logs. |
| |
| <info > [SVR] Copy/paste the below URL in a browser to see the QR Code: |
| <info > [SVR] https://project-chip.github.io/connectedhomeip/qrcode.html?data=CH%3AI34NM%20-00%200C9SS0 |
| |
| **LED 0** shows the overall state of the device and its connectivity. The |
| following states are possible: |
| |
| - _Short Flash On (50 ms on/950 ms off)_ ; The device is in the |
| unprovisioned (unpaired) state and is waiting for a commissioning |
| application to connect. |
| |
| - _Rapid Even Flashing_ ; (100 ms on/100 ms off)_ — The device is in the |
| unprovisioned state and a commissioning application is connected through |
| Bluetooth LE. |
| |
| - _Short Flash Off_ ; (950ms on/50ms off)_ — The device is fully |
| provisioned, but does not yet have full Thread network or service |
| connectivity. |
| |
| - _Solid On_ ; The device is fully provisioned and has full Thread |
| network and service connectivity. |
| |
| **LED 1** Simulates the Lock The following states are possible: |
| |
| - _Solid On_ ; Bolt is unlocked |
| - _Blinking_ ; Bolt is moving to the desired state |
| - _Off_ ; Bolt is locked |
| |
| **Push Button 0** |
| |
| - _Press and Release_ : Start, or restart, BLE advertisement in fast mode. It will advertise in this mode |
| for 30 seconds. The device will then switch to a slower interval advertisement. |
| After 15 minutes, the advertisement stops. |
| |
| - _Pressed and hold for 6 s_ : Initiates the factory reset of the device. |
| Releasing the button within the 6-second window cancels the factory reset |
| procedure. **LEDs** blink in unison when the factory reset procedure is |
| initiated. |
| |
| **Push Button 1** Toggles the bolt state On/Off |
| |
| - You can provision and control the Chip device using the python controller, |
| Chip tool standalone, Android or iOS app |
| |
| [CHIPTool](https://github.com/project-chip/connectedhomeip/blob/master/examples/chip-tool/README.md) |
| |
| Here is some CHIPTool examples: |
| |
| Pairing with chip-tool: |
| ``` |
| chip-tool pairing ble-thread 1 hex:<operationalDataset> 20202021 3840 |
| ``` |
| |
| Set a user: |
| ``` |
| ./out/chip-tool doorlock set-user OperationType UserIndex UserName UserUniqueId UserStatus UserType CredentialRule node-id/group-id |
| ./out/chip-tool doorlock set-user 0 1 "mike" 5 1 0 0 1 1 --timedInteractionTimeoutMs 1000 |
| ``` |
| |
| Set a credential: |
| ``` |
| ./out/chip-tool doorlock set-credential OperationType Credential CredentialData UserIndex UserStatus UserType node-id/group-id |
| ./out/chip-tool doorlock set-credential 0 '{ "credentialType": 1, "credentialIndex": 1 }' "123456" 1 null null 1 1 --timedInteractionTimeoutMs 1000 |
| ``` |
| |
| Changing a credential: |
| ``` |
| ./out/chip-tool doorlock set-credential OperationType Credential CredentialData UserIndex UserStatus UserType node-id/group-id |
| ./out/chip-tool doorlock set-credential 2 '{ "credentialType": 1, "credentialIndex": 1 }' "123457" 1 null null 1 1 --timedInteractionTimeoutMs 1000 |
| ``` |
| |
| Get a user: |
| ``` |
| ./out/chip-tool doorlock get-user UserIndex node-id/group-id |
| ./out/chip-tool doorlock get-user 1 1 1 |
| ``` |
| |
| Unlock door: |
| ``` |
| ./out/chip-tool doorlock unlock-door node-id/group-id |
| ./out/chip-tool doorlock unlock-door 1 1 --timedInteractionTimeoutMs 1000 |
| ``` |
| |
| Lock door: |
| ``` |
| ./out/chip-tool doorlock lock-door node-id/group-id |
| ./out/chip-tool doorlock lock-door 1 1 --timedInteractionTimeoutMs 1000 |
| ``` |
| |
| ### Notes |
| |
| - Depending on your network settings your router might not provide native ipv6 |
| addresses to your devices (Border router / PC). If this is the case, you |
| need to add a static ipv6 addresses on both device and then an ipv6 route to |
| the border router on your PC |
| |
| #On Border Router: \$ sudo ip addr add dev <Network interface> 2002::2/64 |
| |
| #On PC(Linux): \$ sudo ip addr add dev <Network interface> 2002::1/64 |
| |
| #Add Ipv6 route on PC(Linux) \$ sudo ip route add <Thread global ipv6 prefix>/64 |
| via 2002::2 |
| |
| ## Memory settings |
| |
| While most of the RAM usage in CHIP is static, allowing easier debugging and |
| optimization with symbols analysis, we still need some HEAP for the crypto and |
| OpenThread. Size of the HEAP can be modified by changing the value of the |
| `configTOTAL_HEAP_SIZE` define inside of the FreeRTOSConfig.h file of this |
| example. Please take note that a HEAP size smaller than 13k can and will cause a |
| Mbedtls failure during the BLE rendez-vous or CASE session |
| |
| To track memory usage you can set `enable_heap_monitoring = true` either in the |
| BUILD.gn file or pass it as a build argument to gn. This will print on the RTT |
| console the RAM usage of each individual task and the number of Memory |
| allocation and Free. While this is not extensive monitoring you're welcome to |
| modify `examples/platform/efr32/MemMonitoring.cpp` to add your own memory |
| tracking code inside the `trackAlloc` and `trackFree` function |
| |

| ## Building options |
| |
| All of Silabs's examples within the Matter repo have all the features enabled by |
| default, as to provide the best end user experience. However some of those |
| features can easily be toggled on or off. Here is a short list of options : |
| |
| ### Disabling logging |
| |
| `chip_progress_logging, chip_detail_logging, chip_automation_logging` |
| |
| ``` |
| $ ./scripts/examples/gn_efr32_example.sh ./examples/lighting-app/efr32 ./out/lighting-app BRD4164A "chip_detail_logging=false chip_automation_logging=false chip_progress_logging=false" |
| ``` |
| |
| ### Debug build / release build |
| |
| `is_debug` |
| |
| ``` |
| $ ./scripts/examples/gn_efr32_example.sh ./examples/lighting-app/efr32 ./out/lighting-app BRD4164A "is_debug=false" |
| ``` |
| |
| ### Disabling LCD |
| |
| `show_qr_code` |
| |
| ``` |
| $ ./scripts/examples/gn_efr32_example.sh ./examples/lighting-app/efr32 ./out/lighting-app BRD4164A "show_qr_code=false" |
| ``` |
| |
| ### KVS maximum entry count |
| |
| `kvs_max_entries` |
| |
| ``` |
| Set the maximum Kvs entries that can be stored in NVM (Default 75) |
| Thresholds: 30 <= kvs_max_entries <= 255 |
| |
| $ ./scripts/examples/gn_efr32_example.sh ./examples/lighting-app/efr32 ./out/lighting-app BRD4164A kvs_max_entries=50 |
| ``` |
