It's worth mentioning that you can load smartbasic programs over the air and issue certain file management commands over the air. But you can't update the Laird firmware (Nordic soft device+ smartbasic engine).
The RM1xx uses an Nordic nRF51, which has its memory split in two. The first block contains the Nordic soft device and the second block the application. Within that application space, Laird puts the smartbasic engine and creates a filesystem for storage of smartbasic programs, along with some NV storage.
