Does the OTA update expire?


Hi all,

I have 20 Hologram dashs in the field that power up twice a day. I individually performed the OTA update from my desk and expected the update to be delivered as described in this post. To my surprise, all of those that were offline when I sent the update did not update later as I expected. So, my question are…

  1. Do the OTA update requests have a time period for which that are good for?
  2. Will they be dropped if the SMS is not delivered in a certain period of time?
  3. If the device receives the SMS and doesn’t successfully update before it is shut down, will it remember to retrieve the update the next time it boots?
  4. Which Dash MCU controls the OTA update process: user or system?
