Ota Broadcast Bootloader Server Plugin#
Set of APIs for ota-broadcast-bootloader-server.
OTA bootloading plugins are usable to send firmware images Over The Air when the application is running. When the firmware is downloaded to a device, a bootloader can be started to replace the application in the flash to the one just downloaded.
All Connect bootloader-related code relies on the Gecko Bootloader for bootloading and it must be installed on the device for these plugins to work. For details on the Gecko Bootloader, see UG266.
The Broadcast OTA plugins implement the OTA download operation in broadcast, so the same image can be sent to many devices at the same time. The server however requires to know the clients downloading the image, because it implements error handling by querying all clients for missing segments, and then the server will re-broadcast those segments.
Communication relies on standard broadcast data messages, which means routing is not available, and only clients that are in the range of the server can download. However, the same device can be both client and server, i.e. after downloading the image, a client can configure itself to be a server, and provide the image to another part of the network.
Sleepy end devices cannot be addressed in broadcast, but a sleepy end device can reconnect as a normal end device while the OTA is active.
Broadcast OTA uses a plugin configurable endpoint, which is 14 by default.
Security can be also enabled as plugin configuration on the server, as well as the interval of the messages. The client has a timeout plugin configuration after which it stops the OTA session with an error.
See UG235.06 for further details.
Note
OTA Broadcast Bootloading plugins are not available in MAC mode due to the lack of endpoints.
See ota-broadcast-bootloader-server.h and ota-broadcast-bootloader-server.c for source code.
Callbacks#
A callback invoked on the OTA Bootloader Server during an image distribution process to retrieve a contiguous segment of the image being distributed.
A callback invoked on the OTA Bootloader Server when the image distribution process is terminated. The application can use the emberAfPluginBootloaderServerGetTargetStatus() API to retrieve the status reported by each target device.
A callback invoked on the OTA Bootloader Server when bootload request process has completed. Within this callback, the application should use the emberAfPluginBootloaderServerGetTargetStatus() API to retrieve the status and application status reported by each target.
A callback invoked on the OTA Bootloader Server when a bootload request process has completed. Within this callback, the application should use the emberAfPluginBootloaderServerGetTargetStatus() API to retrieve the status and the application status reported by each target.
Functions#
Initiate the image distribution process. The application can use the emberAfPluginBootloaderServerGetTargetStatus() API at any time during the image distribution process to check the status of each target.
Initiate the process to request the status of a set of target devices. The application can use the emberAfPluginBootloaderServerGetTargetStatus() API at any time during the target status request process to check the status of each target.
Start the process where a server requests a set of target devices to initiate the bootload of a received image at some point in the future. The application can use the emberAfPluginBootloaderServerGetTargetStatus() API at any time during the bootload request process to check the status of each target.
Retrieve the locally stored status of an individual target in the distribution list. The locally stored status can be updated by calling emberAfPluginBootloaderServerInitiateRequestTargetsStatus().
Abort the ongoing process (image distribution, status request or bootload request). Note that aborting a bootload request process likely results in some targets performing the bootload while some others do not.
Macros#
The number of consecutive stack message submission errors or stack-related errors, such as CSMA failures, after which the plugin gives up.
The number of consecutive unicast attempts after which a target is declared unreachable. Legal values for this are in the [0,7] range.
The time in milliseconds after which the server gives up waiting for a response from a client.
The maximum number of image broadcast rounds the server performs before declaring an image distribution process failed.
Callbacks Documentation#
emberAfPluginOtaBootloaderServerGetImageSegmentCallback#
bool emberAfPluginOtaBootloaderServerGetImageSegmentCallback (uint32_t startIndex, uint32_t endIndex, uint8_t imageTag, uint8_t * imageSegment)
A callback invoked on the OTA Bootloader Server during an image distribution process to retrieve a contiguous segment of the image being distributed.
