Protocols
Single point firmware is controlled and configured using AT
Commands. Standard multipoint firmware uses a simple packet based
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.
