Does the Dash need to be powered on for an OTA user program (Arduino sketch) to be successfully uploaded?
Background: I’ve been testing the OTA capability via Mac / Arduino IDE 1.6.7. The OTA works wonderfully – it is an AMAZING feature! In my (admittedly limited) testing, it seems to only operate when the Dash is powered on and online. Pushing an OTA update with the Dash powered down seems to dump the OTA into the ocean, as it were – OTA updates pushed when the Dash is powered off don’t seem to take. (Sequence: Dash OFF. Push OTA sketch. Wait 5 minutes. Power on Dash for 10 minutes. Result: Old sketch still loaded) As long as the Dash is on, OTA works super swell, and never seem to take more than a minute or two before the update process begins (progress is handily observable via serial monitor). Awesomesauce.
Are there thoughts / plans to “store” an OTA update in the ether when the Dash is powered down, then have it auto update when re-powererd? Not a necessity by any means, but would like to know your thoughts regarding OTA “best practices and procedures.” Thanks!
