# Running the Matter Demo over Wi-Fi for SiWx917 SoC
## Flashing Images/Binaries on the SiWx917 SoC platform using Ozone or Simplicity Studio and Simplicity Commander
> **Note:**
> 1. SiWx917 SoC device support is available in the latest Simplicity Studio and Simplicity Commander(versions 1v14p5 and above). To flash the TA Firmware/Matter application on SiWx917 SoC,
> - Convert the .s37 file into .rps file using the below command,
>
> `commander rps create <file-name>.rps --app <file-name>.s37`
> - Flash to the device using,
>
> `commander rps load <file-name>.rps`
> 2. Official support for SiWx917 SoC device is not yet available in the Ozone Debugger, but can be configured - [Ozone Environment Setup for SiWx917 SoC](SiWx917_Enablement_For_Ozone.md).
> 3. 917 SoC switch positions: Left switch should be on the **OFF/LOW**, and right switch should be on the **NORMAL** side.
1. Plug the WSTK and SiWx917 radio board into the laptop.
2. Launch the Ozone Debugger.
3. In the **New Project Wizard**:
- Click the three dots (`...`) on the **Device** tab and select the **Manufacturer** as `Silicon Labs`.
- Select the **Device** as `Si917DualFlash`.
- Click **OK**.
- The **Register set** tab is populated automatically.
> **Note:** Entering data in the **Peripherals** tab is optional.
4. Click **Next**. A window will be displayed showing the following:
- Serial Number: Read from device
- Target Interface: JTAG
- Speed: 4MHz
- Host Interface: USB
- One Product in the **Emulators connected via USB** tab
5. Select the Product shown in the **Emulators connected via USB** tab and click **Next**.
6. Click the detected **Silicon Labs device** that gets displayed and click **Next**.
7. Click the three dots (`...`) on that tab, select **Browse** and choose the `*.out` image you wish to flash and run. Click **Next**.
> **Note**: The image you select will be the one built using the instructions on the [Building a Matter Wi-Fi End Device page](./SW_SETUP.md).
8. Make sure the next screen has **Initial PC** selected as `Read from Base Address Vector Table` and click **Finish**.
9. A Diagnostics Warning may be displayed about FreeRTOS being detected. Click **Continue**.
10. Select **Download and Reset Program** in the dropdown next to the **Power** button on the top-left hand corner of the page.
11. The SiWx917 SoC device will be erased and programmed.
12. Click **Reset Program to main (F4)** next to the **Play/Pause** button on the top-left hand corner of the page.
> **Note**: This will reset the MCU after flashing the application.
13. Run the image by clicking the **Resume/Halt** button on the top-left hand corner of the page (or press the **F5** key).
> **Note:**
> 1. The output of the SiWX917 SoC application will be displayed on the Ozone terminal or J-Link RTT Client.
> 2. The RTT Client is provided with Ozone and does not have to be downloaded separately.
## Demo Execution - Commissioning a SiWx917 SoC Device using chip-tool for Linux
> **Note**: Commissioning can be done using chip-tool running either on Linux or Raspberry Pi.
1. Get the SSID and PSK of the Wi-Fi network (WPA2 - Security) you are connected to.
2. Run the following:
```shell
$ cd $MATTER_WORKDIR/matter
```
### Commissioning Command:
```shell
$ out/standalone/chip-tool pairing ble-wifi 1122 $SSID $PSK 20202021 3840
```
> **Note:**
> 1. The Node ID used here is `1122`. This will be used in future commands.
> 2. The below given steps (3, 4, 5) are for Lighting-app, use app specific commands if you are using any other application.
3. To turn **on** the LED on the SiWx917:
```shell
$ out/standalone/chip-tool onoff on 1122 1
```
4. To turn **off** the LED on the SiWx917:
```shell
$ out/standalone/chip-tool onoff off 1122 1
```
5. The updated **on/off** state may be verified with the following command:
```shell
$ out/standalone/chip-tool onoff read on-off 1122 1
```
If you are having difficulty getting the chip-tool to commission the device
successfully, refer to the troubleshooting information on the
[Running the Matter Demos over Wi-Fi on EFR32 hosts page](./RUN_DEMO.md).
As the device remembers the Access Point credentials given for commissioning, if
you want to run the demo multiple times, do a [Factory Reset](./SiWx917SoC_Factory_Reset.md).
The commissioning command mentioned above does the following:
- chip-tool scans BLE and locates the Silicon Labs device that uses the specified discriminator
- Sends the Wi-Fi SSID and Passkey
- The Silicon Labs device will join the Wi-Fi network and get an IP address.
It then starts providing mDNS records on IPv4 and IPv6
- chip-tool then locates the device over Wi-Fi and establishes operational certificates
- Future communications (tests) will then happen over Wi-Fi
