+#CHIP EFR32 OTA Requestor Example
+
+An example showing the use of the Matter OTA Requestor functionality on the
+Silicon Labs EFR32 MG12.
+
+<a name="intro"></a>
+
+## Introduction
+
+The EFR32 OTA Requestor example provides a baseline demonstration the Matter OTA
+Requestor functionality built with the Silicon Labs gecko SDK. It can be
+controlled by a Chip controller over Openthread network..
+
+<a name="building"></a>
+
+## Building
+
+For initial setup steps please see the CHIP EFR32 Lighting Example README at
+examples/lighting-app/efr32/README.md
+
+-   Supported hardware:
+
+    MG12 boards:
+
+    -   BRD4161A / SLWSTK6000B / Wireless Starter Kit / 2.4GHz@19dBm
+    -   BRD4164A / SLWSTK6000B / Wireless Starter Kit / 2.4GHz@19dBm
+    -   BRD4166A / SLTB004A / Thunderboard Sense 2 / 2.4GHz@10dBm
+    -   BRD4170A / SLWSTK6000B / Multiband Wireless Starter Kit / 2.4GHz@19dBm,
+        915MHz@19dBm
+    -   BRD4304A / SLWSTK6000B / MGM12P Module / 2.4GHz@19dBm
+
+    MG21 boards: Currently not supported due to RAM limitation.
+
+    -   BRD4180A / SLWSTK6006A / Wireless Starter Kit / 2.4GHz@20dBm
+
+    MG24 boards :
+
+    -   BRD4186A / SLWSTK6006A / Wireless Starter Kit / 2.4GHz@10dBm
+    -   BRD4187A / SLWSTK6006A / Wireless Starter Kit / 2.4GHz@20dBm
+
+*   Build the example application:
+
+          cd ~/connectedhomeip
+          ./scripts/examples/gn_efr32_example.sh  ./examples/ota-requestor-app/efr32/ ./out/ota-requestor-app BRD4161A
+
+-   To delete generated executable, libraries and object files use:
+
+          $ cd ~/connectedhomeip
+          $ rm -rf ./out/
+
+## Flashing the Application
+
+-   On the command line:
+
+          $ cd ~/connectedhomeip/out/ota-requestor-app/BRD4161A
+          $ python3 chip-efr32-ota-requestor-example.flash.py
+
+-   Or with the Ozone debugger, just load the .out file.
+
+<a name="view-logging"></a>
+
+## Viewing Logging Output
+
+See examples/lighting-app/efr32/README.md
+
+## Running the OTA Download scenario
+
+-   Bring up the Open Thread Border Router as discussed in
+    examples/lighting-app/efr32/README.md and get its operational dataset.
+
+-   On a Linux or Darwin platform build the chip-tool and the ota-provider-app
+    as follows:
+
+           scripts/examples/gn_build_example.sh examples/chip-tool out/
+           scripts/examples/gn_build_example.sh examples/ota-provider-app/linux out/debug chip_config_network_layer_ble=false
+
+-   In a terminal start the provider app passing to it the path to the image
+    file that the Requestor is supposed to download (for example /tmp/ota.out):
+
+                ./out/debug/chip-ota-provider-app -f /tmp/ota.out
+
+-   In a separate terminal run the chip-tool commands to provision the Provider:
+
+             rm -r /tmp/chip_*
+             ./out/chip-tool pairing onnetwork 1 20202021
+
+-   If the Requestor had been previously commissioned hold Button 0 for six
+    seconds to factory-reset the device.
+
+-   In the chip-tool terminal enter:
+
+            ./out/chip-tool pairing ble-thread 2 hex:<operationalDataset> 73141520   3840
+
+where operationalDataset is obtained from the Open Thread Border Router.
+
+-   Once the commissioning process completes enter:
+
+            ./out/chip-tool otasoftwareupdaterequestor announce-ota-provider 1 0 0 0 2 0
+
+-   The Requestor will connect to the Provider and start the image download.
