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…
- Do the OTA update requests have a time period for which that are good for?
- Will they be dropped if the SMS is not delivered in a certain period of time?
- 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?
- Which Dash MCU controls the OTA update process: user or system?
