As I was upgrading my SEMs last night and comparing the two methods (Using Local file or Check for Updates), I realised that with local file I would download the file once and use it multiple times to upgrade multiple SEMs, while with the second option, I guess the upgrade file is downloaded multiple times.
How about an option to upgrade ALL same generation SEMs in one go?
It is not possible to upgrade every one at the same time
Each upgrade needs many commands and data to be sent to the module, and the software must monitor that the commands are successful and there are no errors, and if there is an error, the software needs to handle.
hence only one can be upgraded at a time
The new upgrade method makes is very easy to upgrade firmware compared to before
