Chapter 1 – Product Overview
Overview
The MultiConnect mDot is a programmable, long-range RF module that provides encrypted data connectivity to
sensors, industrial equipment, and remote appliances. By using LoRa
™
Long Range Spread Spectrum technology, bi-
directional data communication can be maintained for distances up to 5 miles/8 km line of sight, deep into
buildings, or within noisy environments
*
using unlicensed ISM bands. mDot simplifies local connectivity for Internet
of Things (IoT) applications.
The mDot features an integrated ARM
®
Cortex
®
-M4 processor and mbed
TM
compatible software library for
developers to control, monitor and bring edge intelligence to their Internet of Things (IoT) applications.
*
Actual distance depends on conditions, configuration, antennas, desired throughput, and usage frequency. In
dense urban environments, a typical range is 1-2 miles.
What's New in Firmware Version 4.0
The new release includes the following changes:
Configuration Persistence
Sleep
FOTA Enhancements
New and updated AT Commands
Configuration Persistence
To safeguard your configuration, the device offers configuration persistence in the form of configuration
redundancy and wear leveling.
Note: These features change the configuration storage and make the firmware update a one way process. The
configuration is not backward compatible to any version less than 4.0.x. Once a device is flashed with 4.0.x
firmware, the configuration is converted to a new format. Any versions earlier than 4.0.x cannot parse this new
format.
mDot Sleep
MDot sleep will use the provided wake mode when executed from application code. Previously it would use the
value in the configuration.
FOTA Enhancements
Bootloader Update
Bootloader can install firmware upgrades from regular files, compressed files, or patch files. Firmware upgrade
images cannot contain a bootloader (application only). Use mbed tools to merge bootloader with application
firmware.
Firmware image manifest
Firmware file manifests allow full images, compressed images, and differential updates.
