OTA update of non-C3 Octavo card software

[andrewgreenberg]

We need the ability to update software on non-C3 Ocatvo cards, like the star tracker, GPS, DxWiFi, and CFC.

The steps are something like this:

• Create software update file and test extensively on flatsat
• Upload software update file to the C3
• Confirm with the ground that the file was uploaded
• Turn on the Octavo card and transfer the file to it
• Confirm with the ground that the file was transferred to the card
• Trigger the software update on the Octavo card
• Get the status of the update back to the ground: maybe back to the C3, through a status file, or through beaconing a version string, or both
