Field upgradeable

Over UART

Single point firmware is controlled and configured using AT

Commands. Standard multipoint firmware uses a simple packet based

Protocols

protocol and requires a host to enable the module to function

effectively.

Single point only allows a point to point connection whereas multipoint

allows more than one simultaneous connection.
