 # ota-requestor-app (Linux)
 
 This is a reference application that is both a server for the OTA Requestor
-Cluster, as well as a client of the OTA Provider Cluster. It should initiate a
-Software Update with a given OTA Provider node, and download a file.
+Cluster, as well as a client of the OTA Provider Cluster. It can initiate a
+software update with a given OTA Provider node, and download a file.
+
+## Building
+
+Suggest doing the following:
+
+```
+scripts/examples/gn_build_example.sh examples/ota-requestor-app/linux out/debug chip_config_network_layer_ble=false
+```
 
 ## Usage
 
-In order to use this reference application to connect to a device running OTA
-Provider server and download a software image, these commands should be called
-in the following order:
+In addition to the general options available to all Linux applications, the
+following command line options are available for the OTA Requestor application.
+
+| Directory                               | Description                                                                                                                                                                       |

-In terminal 1:
+## Software Image Header
+
+All Matter software images must contain a header as defined in section 11.21.1
+of the specification. The
+[ota_image_tool](https://github.com/project-chip/connectedhomeip/blob/master/src/app/ota_image_tool.py)
+is available for generating the required header on a software image. Any
+software images that the OTA Requestor application receives must contain the
+required header. If the header is missing, the software download will not
+succeed.
+
+## Example
+
+One way to use this reference application to connect to a device running OTA
+Provider server and download a software image is to issue an AnnounceOTAProvider
+command. This will trigger a QueryImage command and start the OTA process. To
+test using this method, the following steps should be followed:
+
+### In terminal 1:
+
+**Build the OTA Provider application**
+
+Follow instructions
+[here](https://github.com/project-chip/connectedhomeip/tree/master/examples/ota-provider-app/linux#building)
+
+**Run the OTA Provider application**
 
 ```
-./chip-ota-provider-app -f ${SW_IMAGE_FILE}
+./chip-ota-provider-app --discriminator ${REQUESTOR_LONG_DISCRIMINATOR} --secured-device-port ${REQUESTOR_UDP_PORT} --KVS ${KVS_STORE_LOCATION} --filepath ${SW_IMAGE_FILE}
 ```
 
+-   `{PROVIDER_LONG_DISCRIMINATOR}` is the long discriminator specified for the
+    OTA Provider application for commissioning discovery. If none is supplied,
+    the default is 3840. This must be different from the value used by the OTA
+    Requestor application.
+-   `{PROVIDER_UDP_PORT}` is the UDP port that the OTA Provider application
+    listens on for secure connections. If none is supplied, the default is 5540.
+    This must be different from the value used by the OTA Requestor application.
+-   `{KVS_STORE_LOCATION}` is a location where the KVS items will be stored. If
+    none is supplied, the default is /tmp/chip_kvs. This must be different from
+    the value used by the OTA Requestor application.
 -   `${SW_IMAGE_FILE}` is the file representing a software image to be served.
+    This file must include a header as defined in the specification.
 
-In terminal 2:
+### In terminal 2:
 
-```
-./chip-tool pairing onnetwork ${NODE_ID_TO_ASSIGN_PROVIDER} 20202021
-```
+**Build the OTA Requestor application**
 
--   `${NODE_ID_TO_ASSIGN_PROVIDER}` is the node id to assign to the
-    ota-provider-app running in terminal 1.
+Follow instructions
+[here](https://github.com/project-chip/connectedhomeip/tree/master/examples/ota-requestor-app/linux#building)
 
-In terminal 3:
+**Run the OTA Requestor application:**
 
 ```
-./chip-ota-requestor-app -d ${REQUESTOR_LONG_DISCRIMINATOR} -u ${REQUESTOR_UDP_PORT} -n ${PROVIDER_NODE_ID} -f ${PROVIDER_FABRIC_INDEX} -q ${DELAY_QUERY_SECONDS}
+./chip-ota-requestor-app --discriminator ${REQUESTOR_LONG_DISCRIMINATOR} --secured-device-port ${REQUESTOR_UDP_PORT} --KVS ${KVS_STORE_LOCATION}
 ```
 
 -   `{REQUESTOR_LONG_DISCRIMINATOR}` is the long discriminator specified for the
-    ota-requestor-app for commissioning discovery
--   `{REQUESTOR_UDP_PORT}` is the UDP port that the ota-requestor-app listens on
-    for secure connections
--   `${PROVIDER_IP_ADDRESS}` is the IP address of the ota-provider-app that has
-    been resolved manually
--   `${PROVIDER_NODE_ID}` is the node ID of the ota-provider-app; this is a Test
-    Mode parameter and should not be used in most scenarios
--   `${PROVIDER_FABRIC_INDEX}` is the fabric index of the ota-provider-app; this
-    is a Test Mode parameter and should not be used in most scenarios
--   `${DELAY_QUERY_SECONDS}` is the amount of time in seconds to wait before
-    initiating secure session establishment and query for software image

-```
+### In terminal 3:
 
--   `${NODE_ID_TO_ASSIGN_REQUESTOR}` is the node id to assign to the
-    ota-requestor-app running in terminal 3
--   `${REQUESTOR_LONG_DISCRIMINATOR}` is the long discriminator of the
-    ota-requestor-app specified in terminal 3 above
+**Commission the OTA Provider application**
 
 ```
-./chip-tool otasoftwareupdaterequestor announce-ota-provider ${PROVIDER_NODE_ID} 0 0 0 ${REQUESTOR_NODE_ID} 0
+./chip-tool pairing onnetwork-long ${PROVIDER_NODE_ID} 20202021 ${PROVIDER_LONG_DISCRIMINATOR}
 ```
 
--   `${PROVIDER_NODE_ID}` is the node ID of the ota-provider-app assigned to it
-    during the pairing step above
--   `${REQUESTOR_NODE_ID}` is the node ID of the ota-requestor-app assigned to
-    it during the pairing step above
-
-## Note
-
-When the Provider, Requestor and chip-tool are run on the same Linux node the
-user must issue `rm -r /tmp/chip_*` before starting the Provider and
-`rm /tmp/chip_kvs` before starting the Requestor. These commands reset the
-shared Key Value Store to a consistent state.
+-   `${PROVIDER_NODE_ID}` is the node id to assign to the OTA Provider
+    application running in terminal 1
+-   `${PROVIDER_LONG_DISCRIMINATOR}` is the long discriminator of the OTA
+    Provider application specified in terminal 1 above
 
-## Example
-
-Building:
+**Commission the OTA Requestor application**
 
 ```
-scripts/examples/gn_build_example.sh examples/chip-tool out/ chip_config_network_layer_ble=false && scripts/examples/gn_build_example.sh examples/ota-provider-app/linux out/debug chip_config_network_layer_ble=false  && scripts/examples/gn_build_example.sh examples/ota-requestor-app/linux out/debug chip_config_network_layer_ble=false
+./chip-tool pairing onnetwork-long ${REQUESTOR_NODE_ID} 20202021 ${REQUESTOR_LONG_DISCRIMINATOR}
 ```
 
-Running (in separate terminals as described above):
+-   `${REQUESTOR_NODE_ID}` is the node id to assign to the OTA Requestor
+    application running in terminal 2
+-   `${REQUESTOR_LONG_DISCRIMINATOR}` is the long discriminator of the OTA
+    Requestor application specified in terminal 2 above
+
+**Issue the AnnounceOTAProvider command**
 
 ```
-rm -r /tmp/chip_*
-./out/debug/chip-ota-provider-app -f /tmp/ota.txt
-./out/chip-tool pairing onnetwork 1 20202021
-rm /tmp/chip_kvs

--   Code for running a full BDX download exists in BDX
--   Sends QueryImage command
--   Downloads a file over BDX served by an OTA Provider server
