Chapter 1 – Product Overview
Overview
The MultiConnect xDot (MTXDOT) is a LoRaWAN
TM
, low-power RF device, capable of two way communication over
long distances, deep into buildings, or within noisy environments
*
using the unlicensed ISM bands in North
America, Europe and worldwide. The xDot is a compact surface-mount device with an mbed enabled processor and
enhanced security. The xDot features an integrated ARM
®
Cortex
®
-M3 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 3.1
The new release includes the following changes:
xDot Bootloader
Power Optimization
Other Enhancements
xDot Bootloader
The xDot bootloader allows firmware upgrades via ymodem over either the command or debug serial ports. For
details, refer to
Updating Firmware Using the xDot Bootloader .
Power Optimization
To reduce power consumption during Class A transactions, Version 3.1 firmware includes a new auto sleep feature.
When enabled, the microcontroller automatically goes into a stop sleep mode after an uplink transmit ends and in
between two receive windows. In the stop sleep mode, RAM and register contents are retained, but all peripheral
clocks are gated, so timers will not count during these intervals. Refer to the microcontroller datasheet for
information regarding microcontroller sleep mode states.
New AT Command: +AS - Auto Sleep
Other Enhancements
Adaptive Data Rate (ADR) is now enabled by default.
Public Network command, +PN, has been updated to include an MTS network in addition to the LoRaWAN
public or private network options. This includes changes to parameter values. Refer to the +PN command in
S000643 DOT Series AT Command Reference Guide for details.
