Ota Broadcast Bootloader Common#
Set of types defined for ota-broadcast-bootloader.
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.

OTA Broadcast Bootloader return status codes.
| Enumerator | |
|---|---|
| EMBER_OTA_BROADCAST_BOOTLOADER_STATUS_SUCCESS | The generic "no error" message. |
| EMBER_OTA_BROADCAST_BOOTLOADER_STATUS_INVALID_CALL | Indicates that some parameters are invalid, or the OTA server/client is not in the expected state for the call |
| EMBER_OTA_BROADCAST_BOOTLOADER_STATUS_BUSY | Indicates that the OTA server is busy performing another OTA task |
| EMBER_OTA_BROADCAST_BOOTLOADER_STATUS_NO_BUFFERS | Indicates that the OTA server couldn't allocate memory from the heap (See Memory Buffer for details). |
| EMBER_OTA_BROADCAST_BOOTLOADER_STATUS_DATA_UNDERFLOW | Indicates that the application did not provided the requested data to the OTA server |
| EMBER_OTA_BROADCAST_BOOTLOADER_STATUS_STACK_ERROR | Indicates that the Connect stack returned an error to the OTA client/server. |
| EMBER_OTA_BROADCAST_BOOTLOADER_STATUS_TIMEOUT | Indicates that the OTA image download is timed out during missing segment requests. |
| EMBER_OTA_BROADCAST_BOOTLOADER_STATUS_FAILED | Indicates that the OTA image download is failed during the broadcast phase. |
| EMBER_OTA_BROADCAST_BOOTLOADER_STATUS_ABORTED | Indicates that the application aborted the OTA process. |

EmberAfOtaBootloaderTargetStatus
OTA Broadcast Bootloader target status codes, returned by emberAfPluginBootloaderServerGetTargetStatus().
| Enumerator | |
|---|---|
| EMBER_OTA_BROADCAST_BOOTLOADER_TARGET_STATUS_INVALID | The passed node ID does not appear in the current server target list of the current ongoing process or there is no current ongoing process. |
| EMBER_OTA_BROADCAST_BOOTLOADER_TARGET_STATUS_UNREACHABLE | The target has not responded to any of the server's unicast messages. |
| EMBER_OTA_BROADCAST_BOOTLOADER_TARGET_STATUS_DISTRIBUTION_COMPLETED | The server is currently performing an image distribution process and the target confirmed that it received the full image. |
| EMBER_OTA_BROADCAST_BOOTLOADER_TARGET_STATUS_DISTRIBUTION_ONGOING | The server is currently performing an image distribution process and the target has partially received the image and distribution is continuing. |
| EMBER_OTA_BROADCAST_BOOTLOADER_TARGET_STATUS_DISTRIBUTION_FAILED | The server is currently performing an image distribution process and the target reported that an error was encountered. |
| EMBER_OTA_BROADCAST_BOOTLOADER_TARGET_STATUS_DISTRIBUTION_REFUSED | The target has refused the current image. |
| EMBER_OTA_BROADCAST_BOOTLOADER_TARGET_STATUS_DISTRIBUTION_ABORTED | The server is currently performing an image distribution process and the target decided to abort the image download process. In this case, the client also reports an application status. |
| EMBER_OTA_BROADCAST_BOOTLOADER_TARGET_STATUS_STATUS_REQUEST_COMPLETED | The server is currently performing a target status request process and the target has responded to the server's inquiry. In this case, the client also reports an application status. |
| EMBER_OTA_BROADCAST_BOOTLOADER_TARGET_STATUS_STATUS_REQUEST_ONGOING | The server is currently performing a target status request process and the target is not yet queried by the server. |
| EMBER_OTA_BROADCAST_BOOTLOADER_TARGET_STATUS_BOOTLOAD_REQUEST_ACCEPTED | The server is currently performing a bootload request process and the target has accepted to perform the requested image bootload. |
| EMBER_OTA_BROADCAST_BOOTLOADER_TARGET_STATUS_BOOTLOAD_REQUEST_ONGOING | The server is currently performing a bootload request process and the target is not yet reached by the server. |
| EMBER_OTA_BROADCAST_BOOTLOADER_TARGET_STATUS_BOOTLOAD_REQUEST_REFUSED | The server is currently performing a bootload request process and the target has refused to perform the requested image bootload. |
