OTA Messages
Create and manage over-the-air messages to select sentinels.
OTA Overview
Filters: Set of filters available to filter through existing over-the-air messages.
Download CSV: Download the table of over-the-air messages as a CSV.
Create New OTA Message: Open the modal to create an over-the-air message to a single or multiple devices.
Message ID: The unique id associated with the over-the-air message.
Message Type: The message type id associated with the over-the-air message. More information on message types can be found below.
Message Index: The index associated with the over-the-air message. Only used for OTA messages that are broken into multiple messages due to their size (like firmware updates).
Device ID: The device ID of the sentinel that the message is sent to.
Device Name: The device name of the sentinel that the message is sent to.
Message Provider: The id of the message provider used by the sentinel (currently only Blues Cellular).
Status: The status of the over-the-air message:
sent: The message has been sent, but has not been processed by the sentinel.
success: The message has been processed correctly by the sentinel.
failed_on_device: The message has been processed, but encountered some issue on the sentinel. This is often caused by: requesting a higher res image that no longer exists on the device or attempting to change the model on the device to a model that does not exist on the device.
failed_to_send: The message encountered an issues with the message provider that prevented it from being sent. Attempt to send the message again. If it still fails, contact the sentinel support.
Created At: The UTC date associated with when the over-the-air message was created.
Message: The contents of the message sent to the sentinel. For large messages (example firmware update), no message is displayed.
More "triple dot" options: Set which columns to display in the table.
Message Type - update_state
Updates the cycle time and trigger number on the device IDs requested.
Message Type - update_model_settings
Updates the release ID on the device IDs requested. The release ID is associated with an algorithm release that contains all configurations associated with a set of models on the device. Due to the size of the model files, only the configurations can be changed. If new model files need to be loaded on the device, bring the sentinel into WiFi range and use a device update. Contact sentinel support for more information.
Message Type - reset_device
Deletes all images in the backlog folder, removes the on-device database, and removes any temp directories on device. All images in raw and results are saved.
Message Type - firmware_update
Updates the firmware on the device to the firmware version specified (currently only alpha). This over-the-air message can take multiple device cycles to complete.
Message Type - request_higher_res_image
Located on the Insights tab, the insights modal contains a "Request Higher Resolution Image" button that will send an over-the-air message to the device to retrieve a higher resolution image for the selected insight. The new image will be the complete image with a red box highlighting the area of interest for the insight.
To open the insights modal, click on any insight within the insights table.
