Hi Jim. Thanks for the description.
What the ‘ini’ reader does is read a file on the Mayfly microSD card called ms_cfg.ini – in that file is all the configuration information that is specific to a particular node “station” as when the MMW sensor UUIDs are created.
What this does is allow your .ino file to be compiled once to a .HEX, with no custom UUIDs. All the node specific MMW UUIDs are then put in the individual “Stations” Mayfly microSD files.
The Mayfly’s mega1284 is a small 8bit microprocessor, and there is very limited networking capability – not like a linux system that has a lot of generic networking. So no there is no capability to push a UUID back onto the Mayfly.
On MMW I couldn’t find a way of searching for Sites GMI_* it needs the Organization to be first specified.
