MOTE USER’S GUIDE
Chapter 2. Getting Started
2.1 INTRODUCTION
This LoRa® Mote User’s Guide is designed to be used in conjunction with the LoRa
Technology Command Reference User’s Guide for the on-board LoRa module. This
chapter describes the hardware requirements for the LoRa Mote board, and also
provides descriptions of the different communication modes.
The module accepts commands via UART interface. Communication with the module
is achieved through two methods of operation, USB and Battery.
This chapter discusses the following topics:
• Operation Methods
• Communication to the Module
• Hardware Description
2.2 METHODS OF OPERATION
2.2.1 USB
When the Mote board is connected to the host via USB, the device will operate
automatically in USB mode. The on-board PIC18LF45K50 MCU will become a
USB-to-UART bridge device. The host can run a simple terminal emulator application
to issue commands directly to the module.
When in CDC Command mode, it is possible to operate in Battery mode by pressing
either push button. The Mote will only forward Serial commands to the RN module
when in CDC Command mode. If running in Battery mode with the USB cable
connected; disconnecting and reconnecting the USB cable is required to return to
normal USB mode for CDC serial command parsing emulation.
Supply voltage is provided via USB, and is regulated from 5V to the nominal 3.3V using
the on-board LDO (U1).
2.2.2 Battery
When no USB cable is attached, and the board is powered by (2) AAA batteries (B1),
the Mote is operating in Battery mode.
In Battery Operation mode, the Microchip PIC18LF45K50 PIC® MCU on the Mote unit
can run custom functions and directly issue ASCII commands to the attached LoRa
module via the UART interface.
The on-board MCU influences UART communications specific to operation states.
Additional resources exist on the MCU, allowing further custom development by the
user.

DS40001808B-page 14 2015-2016 Microchip Technology Inc.
2.3 HARDWARE DESCRIPTION
The RF signal paths are connected to the SMA edge connector and the designated via
through-hole point. The high-frequency (868/915 MHz band) RF signal is transmitted
through the RFH (J3) SMA connector. The low-frequency (433 MHz) RF signal is
transmitted via the through-hole point (RFL), this allows connection of a user-supplied
wire antenna.
The on-board PIC18LF45K50 MCU is programmable via ICSP™ through connector J2.
In addition, the PIC18LF45K50 MCU application program is capable of being updated
via the bootloader utility.
The Mote board will power-on automatically when a USB cable is connected. When
powered by AAA batteries, power-on/off is controlled using the (S3) switch
.
Mote environment data is measured by a light sensor (U4) and by a temperature sensor
(U5). There are two on-board push buttons (S2, S3) used for menu navigation and
selection. In addition, there are four LEDs. Two LEDs (D3-Orange, D4-Green) are
connected to the module’s GPIO10 and GPIO11 I/O’s. Two LEDs (D5-Red, D6-Green)
are connected to and controlled by the PIC18LF45K50 device.
Table 2-2 shows the LoRa® Mote PIC18LF45K50 connections:
Note: The North-American (915 MHz) module does not support the ability to
transmit a (433 MHz) low-frequency signal.

The populated module (U7) is re-programmable via the ICSP™ press pin pad
programming connector point (J5). In addition, the populated LoRa module is capable
of being updated via the LoRa® bootloader GUI, as described in the RN2483 LoRa®
Technology Module Command Reference User’s Guide (DS40001784),
RN2903 LoRa® Technology Module Command Reference User’s Guide
(DS40001811), or LoRa® Technology Evaluation Suite User’s Guide (DS40001847).
All the pins of the module can be accessed via surface-mount pads located on both
sides of the (U7) connection point. The user can mount two 1.27 mm pitched socket
headers if desired. Sockets can connect the module pins to a custom board, whereas
the Mote board is capable of providing power. The sockets are broken into two header
breakout groupings used in supplying connection points to the module’s power, ground
and additional GPIO/UART pins.

2.4 MOTE APPLICATION DESCRIPTION
This section describes the basic operation of the LoRa Mote application program.
The default LoRa Mote application comes with three methods of operation:
• USB CDC-Serial Communication
• Mobile Mote Sensor Emulation
• Application Update via Bootloader
2.4.1 USB CDC-Serial
When a USB Mini-B is connected to the LoRa Mote, it will power-on, regardless of the
power switch S3. If the LoRa Mote is already in operation, the USB connection will take
pre-emptive control and act only as a serial emulation device. After being connected to
a host PC, the LoRa Mote will enumerate. In this operation mode, the user can enter
the required LoRaWAN™ credentials for joining an existing LoRaWAN network.
There is a wide range of third-party serial communication programs which can be used
to communicate with the module populated on the LoRa Mote. Refer to the RN2483
LoRa® Technology Module Command Reference User’s Guide (DS40001784) for
additional information on parsing commands directly into the RN module for LoRa
communications.
2.4.2 Mobile Mote Sensor Emulation
When powered using (2) AAA batteries, the LoRa Mote will act in Mobile Mote mode.
This application is best used to demonstrate a real working Internet of Things (IoT)
sensor design.
After power-on, the LoRa Mote will attempt a LoRaWAN network first through either
Activation-By-Personalization (ABP) [S2], or Over-The-Air-Activation (OTAA) [S3];
depending upon the type requested. If the proper keys necessary to join the requested
process (ABP, OTAA), the LoRa Mote will display the message “Valid Keys Required”.
The user will then have to enter the required keys of the module through USB
CDC-Serial mode, and store them using the ‘mac save’ command. The minimal
required credentials for each join process are indicated below:
•OTAA
-DevEUI
-AppEUI
-AppKey
•ABP
- DevAddr

If the proper credentials are entered, the LoRa Mote will automatically join the system.
After joining, the LoRa Mote will enter Running mode.
When running, the LoRa Mote acts as a demonstration device. It is capable of key
LoRa communication events, such as manual uplink packets, automatic periodic uplink
packets, and displaying last received downlink data.
Menu navigation is handled by using S2 for navigation and S3 for selection.
Note: MPCOMMS is required to be installed for USB enumeration. This is
installed automatically together with MPLAB® X.

Table 2-4 shows the menus with operation descriptions:
2.4.3 Bootloader Behavior
The PIC18LF45K50 is pre-programmed with a bootloader application. Bootloader
mode is initiated by holding either S2/S3 or both push buttons upon power-up.
The bootloader applications are based off the HID bootloader – PIC18 Non-J; the
project is supplied with the Microchip Libraries for Applications (MLA) that can be found
at www.microchip.com/mla.
In addition, the utility supplied with the MLA is used to handle all Mote PIC® MCU
application bootloading behaviors.
TABLE 2-4: DESCRIPTION OF MENU OPERATION
Menu Description
Sensor Display Displays Light and Temperature Sensor Data
Issue uplink (S2) issues a confirmed uplink message with sensor data
payload.
(S3) issues an unconfirmed uplink message with sensor data
payload.(1)
View downlink When the red LED (D5) is lit, a downlink message is ready for
viewing.
This menu will display the received downlink payload.
Menu Timeout Configures/Disables the Sleep time-out features of the Mote.
Disabling this feature will prevent the Mote to automatically enter
sleeping if inactive. If not disabled, the Menu time out contains
varying options in length. Menu time-out length is represented in
seconds.
Perform Periodic
Sleep Uplinks Configures/Disables the ability for the Mote to issue Uplink
Transmissions when asleep. Configures the rate at which the
Mote is periodically woken from Sleep through use of the
Watchdog Timer. Periodic Uplink Transmission lengths are
represented in minutes.
Select Data Rate Configures the working Data Rate for the RN module. Available
Data Rate options are dependent upon the populated RN module
type. Selection of Adaptive Data Rate (ADR) is also available.
Upon exiting the menu will issue configuration commands to the
RN module where parameter value is “saved”.
Sleep Control The LoRa® Mote will automatically enter Sleep if no buttons are
pressed for 30 seconds. The LoRa Mote can be placed into Sleep
manually by selecting the Sleep option in the menus.
Wake-Up events include:
• Pressing either S2 or S3 push buttons
• A USB plug-in
• Periodic WDT (Watchdog Timer) ticks
• Module message reception
Note 1: The port number used for Mote uplink messages is randomly selected
between 1-223.
Note: Additionally, the module contains its own bootloader application which can
be accessed/updated as discussed in the RN2483 LoRa® Technology
Module Command Reference User’s Guide (DS40001784)

2.4.4 Application Updates
• If powered by USB cable, the red LED (D3) and the green LED (D4) will begin to
alternate ON/OFF.
• If the device is in Battery Operation mode and the Bootloader mode is entered,
the red LED (D3) will stay ON, the green LED (D4) will remain OFF. Once the USB
cable is plugged-in, the green/red LED will alternate.
The application firmware can be updated by launching the HID bootloader GUI application
included with the Microchip Libraries for Applications (MLA) at www.microchip.com/mla.
DIR:
\\mla\v2014_07_22\apps\usb\device\bootloaders\utilities\bin\win\HIDBootloader.exe
Note: If Bootloader mode is entered unintentionally, power cycling the board will
re-enter the LoRa® Mote default application.
