The Microchip RN2483 module provides LoRaWAN™ protocol connectivity using a
simple UART interface. This module handles the LoRaWAN Class A and Class C
protocols and provides an optimized text command/response interface to the host
system. This document is intended to describe an implementation of the LoRaWAN
Class A and Class C protocols. LoRaWAN protocol terms are described in more detail
in the LoRaWAN™ Specification V1.0.2 available from the LoRa Alliance
(http://www.lora-alliance.org). Thus, it is recommended to review the LoRaWAN™ Specification V1.0.2 before using the RN2483 module.
The required configuration for accessing a LoRa technology network is minimal and
can be stored in the module’s EEPROM, allowing for factory configuration of these
parameters, lowering the requirements for the host system while also increasing
system security. The module also features GPIO pins that can be configured through
the UART interface.
A simple use case is described in Figure 1-1where an end device, containing a host
MCU which reads a sensor, commands the RN2483 to transmit the sensor reading
over the LoRa network. Data are encrypted by the RN2483 and the radio packet is
received by one or multiple gateways which forward it to the network server. The
network server sends the data to the application server which has the key to decrypt
the application data. Similarly, a development platform may consist of an RN2483
directly connected over UART to a PC which becomes the host system in this case.
Users can then type commands into the module using a terminal program.
The flow of data can be followed as it gets generated by an end device and transported
on the network.
1.2FEATURES
• LoRaWAN Class A and Class C protocol compliance
• Integrated FSK, GFSK and LoRa technology transceiver allowing the user to
transmit custom packets using these protocols
• Globally unique 64-bit identifier (EUI-64™)
• Configurable GPIOs
• Intelligent Low-Power mode with programmable/on-demand wake up
• Bootloader for firmware upgrade
• All configuration and control done over UART using simple ASCII commands
Refer to the RN2483, Low-Power Long-Range LoRa
Data Sheet
(DS50002346)for details on the hardware specifications of the module.

1.3CONFIGURATION
The RN2483 module’s architecture is described in Figure 1-2 from the command
interface point of view. There are three types of commands that can be used, and each
allows access to different module functions:
• LoRaWAN Class A and Class C configuration and control, using the mac group of
commands
• Low-level radio configuration and control, using the radio group of commands
• Other module functions, using the sys group of commands
FIGURE 1-2:RN2483 COMMAND INTERFACE (YELLOW) AND ITS
RELATIONSHIP TO THE MODULE’S INTERNAL
COMPONENTS
The available commands can be used to configure and control the LoRaWAN protocol
layer, the radio driver and some system peripherals.
In order to communicate with a LoRa network, a specific number of parameters need
to be configured. Since two distinctive methods are offered for a device to become part
of the network, each of these requires different parameters:
• Over-the-Air Activation (OTAA), where a device negotiates network encryption
keys at the time it joins the network. For this, the device EUI, application EUI and
application key need to be configured and then the OTAA procedure can start.
• Activation by Personalization (ABP) where the device already contains the
network keys and can directly start communication with the network. Configuring
DS40001784G-page 12 2015-2018 Microchip Technology Inc.
the device address, network session key and application session key is sufficient
for this type of initialization.
For increased security, these parameters can be configured and stored in the module’s
EEPROM during manufacturing of devices requiring LoRaWAN connectivity. Thus, the
keys do not need to be sent over the UART interface by the host system every time the
device powers up.
1.4UART INTERFACE
All of the RN2483 module’s settings and commands are transmitted over UART using
the ASCII interface.
All commands need to be terminated with <CR><LF> and any replies they generate will
also be terminated by the same sequence.
The default settings for the UART interface are 57600 bps, 8 bits, no parity, 1 Stop bit,
no flow control. The baud rate can be changed by triggering the auto-baud detection
sequence of the module. To do this, the host system needs to transmit a Break
condition to the module followed by a 0x55 character at the new baud rate. The
auto-baud detection mechanism can also be triggered during sleep to wake the module
up before the predetermined time has expired.
Note:A break condition is signaled to the module by keeping the UART_RX pin
Introduction
low for longer than the time to transmit a complete character. For example,
at the default baud rate of 57600 bps, keeping the UART_RX pin low for
226 s is a valid 13-bit break condition, whereas at 9600 bps this may be
interpreted as a 0x00 character. Thus, the Break condition needs to be
long enough to still be interpreted as such at the baud rate that is currently
in use. At 9600 bps a valid 13-bit Break condition must need to be 1,350 s.
Break condition calculation is as follows:
T
= Nb/bps
b
Where:
= time required for Break condition
* T
b
* Nb = number of bits required for Break condition
* bps = current bit rate
DS40001784G-page 14 2015-2018 Microchip Technology Inc.
Chapter 2. Command Reference
The RN2483 LoRa technology module supports a variety of commands for
configuration. This section describes these commands in detail and provides
examples.
2.1COMMAND SYNTAX
To issue commands to the RN2483 module, the user sends keywords followed by
optional parameters. Commands (keywords) are case-sensitive, and spaces must not
be used in parameters. Hex input data can be uppercase or lowercase. String text data,
such as OTAA used for the join procedure, can be uppercase or lowercase.
The use of shorthand for parameters is NOT supported.
Depending on the command, the parameter may expect values in either decimal or
hexadecimal form; refer to the command description for the expected form. For
example, when configuring the frequency, the command expects a decimal value in
Hertz such as 868100000 (868.1 MHz). Alternatively, when configuring the LoRaWAN
device address, the hex value is entered into the parameter as aabbccdd. To enter a
number in hex form, use the value directly. For example, the hex value 0xFF would be
entered as FF.

2.2COMMAND ORGANIZATION
There are three general command categories, as shown in Table 2-1.
TABLE 2-1:COMMAND TYPES
Command TypeKeywordDescription
System<sys>Issues system level behavior actions, gathers status
LoRaWAN™ Class A

Transceiver commands <radio> Issues radio specific configurations, directly accessing
information on the firmware and hardware version, or
accesses the module user EEPROM memory.
<mac>Issues LoRaWAN Class A and Class C protocols
network communication behaviors, actions and
configuration commands.
After configuring the LoRaWAN protocol settings, the user must save them to
EEPROM with the mac save command. Once the settings have been saved, they will
be retained after a reboot or Reset.
Note: Upon successful reception a command, based on the specific command,
the module will respond with one of the following:
•ok
•busy
•fram_counter_err_rejoin_needed
•invalid_class
•invalid_data_len
•invalid_param
•keys_not_init
•mac_paused
•multicast_keys_not_set
•no_free_ch
•not_joined
•silent
•err
Note:To facilitate the sharing of the radio between user custom applications and
the LoRaWAN MAC, refer to the mac pause and mac resume commands.
Since no sharing exists between sys and other types of commands, there
is no need for additional pause commands.
2.3SYSTEM COMMANDS
System commands begin with the system keyword <sys> and include the categories
shown in Ta b le 2 - 2, Ta bl e 2 - 3 and Table 2-4.

This command puts the system to sleep for the specified number of milliseconds. The
module can be forced to exit from sleep by sending the UART a Break condition
followed by a 0x55 character. Forcing the module from sleep in the manner also
triggers the UART auto baud detection. The module will adjust the UART baud rate to
match the baud rate at which the 0x55 character was sent. Refer to the note box in
1.4 “UART Interface”.
Example: sys sleep 120 // Puts the system to sleep for 120 ms.
2.3.2sys reset

parameters. Everything set prior to this command will lose its set value.
<type>:string representing the uplink payload type, either cnf or uncnf (cnf –
confirmed, uncnf – unconfirmed)
<portno>: decimal number representing the port number, from 1 to 223
<data>:hexadecimal value. The length of <data> bytes capable of being
transmitted are dependent upon the set data rate (for further details, refer
to the LoRaWAN™ Specification V1.0.2).
Response: this command may reply with two responses. The first response will be
received immediately after entering the command. In case the command is
valid (ok reply received), a second reply will be received after the end of the
uplink transmission. For further details, refer to the LoRaWAN™ Specification V1.0.2.
Response after entering the command:
• ok – if parameters and configurations are valid and the packet was forwarded to
the radio transceiver for transmission
• invalid_param – if parameters (<type><portno><data>) are not valid
• not_joined – if the network is not joined
• no_free_ch – if all channels are busy
• silent – if the module is in a Silent Immediately state
• frame_counter_err_rejoin_needed – if the frame counter rolled over
• busy – if MAC state is not in an Idle state
• mac_paused – if MAC was paused and not resumed back
• invalid_data_len if application payload length is greater than the maximum
application payload length corresponding to the current data rate
Response after the first uplink transmission attempt:
• mac_tx_ok if uplink transmission was successful and no downlink data was
received back from the server;
• mac_rx <portno> <data> if transmission was successful, <portno>: port
number, from 1 to 223; <data>: hexadecimal value that was received from the
server;
• mac_err if transmission was unsuccessful, ACK not received back from the
server
• invalid_data_len if application payload length is greater than the maximum
application payload length corresponding to the current data rate. This can occur
after an earlier uplink attempt if retransmission back-off has reduced the data rate.
A confirmed message will expect an acknowledgment from the server; otherwise, the
message will be retransmitted by the number indicated by the command mac set retx <value>, whereas an unconfirmed message will not expect any
acknowledgment back from the server. For further details, refer to the LoRaWAN™ Specification V1.0.2.
The port number allows multiplexing multiple data streams on the same link. For
example, the end device can send measurements on one port number and
configuration data on another. The server application can then distinguish the two types
of data based on the port number.
Example: mac tx cnf 4 5A5B5B // Sends a confirmed frame on port 4 with
application payload 5A5B5B.

Command Reference
If the automatic reply feature is enabled and the server sets the Frame Pending bit or
initiates downlink confirmed transmissions, multiple responses will be displayed after
each downlink packet is received by the module. A typical scenario for this case would
be (prerequisites: free LoRaWAN channels available and automatic reply enabled):
• The module sends a packet on port 4 with application payload 0xAB
• Radio transmission is successful and the module will display the first response:
ok
• The server needs to send two separate downlink confirmed packets back on port
1 with the following data: 0xAC, then 0xAF. First it will transmit the first one (0xAC)
and will set the Frame Pending bit. The module will display the second response
mac_rx 1 AC
• The module will initiate an automatic uplink unconfirmed transmission with no
application payload on the first free channel because the Frame Pending bit was
set in the downlink transmission
• The server will send back the second confirmed packet (0xAF). The module will
display a third response mac_rx 1 AF
• The module will initiate an automatic unconfirmed transmission with no application
payload on the first free channel because the last downlink transmission was
confirmed, so the server needs an ACK
• If no reply is received back from the server, the module will display the fourth
response after the end of the second Receive window: mac_tx_ok
• After this scenario, the user is allowed to send packets when at least one enabled
channel is free
Based on this scenario, the following responses will be displayed by the module:
<mode>:string representing the join procedure type (case-insensitive), either otaa
or abp (otaa – over-the-air activation, abp – activation by
personalization).
Response: this command may reply with two responses. The first response will be
received immediately after entering the command. In case the command is
valid (ok reply received) a second reply will be received after the end of the
join procedure. For further details, refer to the LoRaWAN™ Specification V1.0.2.
Response after entering the command:
• ok – if parameters and configurations are valid and the join request packet was
forwarded to the radio transceiver for transmission
• invalid_param – if <mode> is not valid
• keys_not_init – if the keys corresponding to the Join mode (otaa or abp)
were not configured
• no_free_ch – if all channels are busy
• silent – if the device is in a Silent Immediately state
• busy – if MAC state is not in an Idle state
• mac_paused – if MAC was paused and not resumed back
Response after the join procedure:
• denied if the join procedure was unsuccessful (the module attempted to join the
network, but was rejected);
• accepted if the join procedure was successful;
This command informs the RN2483 module it should attempt to join the configured
network. Module activation type is selected with <mode>. Parameter values can be
otaa (over-the-air activation) or abp (activation by personalization). The <mode>
parameter is not case sensitive. Before joining the network, the specific parameters for
each activation type should be configured (for over the air activation: device EUI,
application EUI, application key; for activation by personalization: device address,
network session key, application session key).
Example: mac join otaa// Attempts to join the network using
over-the-air activation.

Command Reference
2.4.4mac save
Response: ok
The mac save command must be issued after configuration parameters have been
appropriately entered from the mac set <cmd> commands. This command will save
LoRaWAN Class A protocol configuration parameters to the user EEPROM. When the
next sys reset command is issued, the LoRaWAN Class A protocol configuration will
be initialized with the last saved parameters.
The LoRaWAN protocol configuration savable parameters are:
• adr: ADR state
• appeui: Application Identifier
• appkey: Application Key
• appskey: Application Session key
• ch: All Channel Parameters
- drrange: Data Rate Range
- status: Status
• class: LoRaWAN operating Class
• devaddr: End-Device Address
• deveui: End-Device Identifier
• dnctr: Downlink Frame Counter
• dr:Data Rate
• join flags: Join parameter flags
- appeui: Application Identifier set
- appmultiskey: Application Multicast Session Key set
- appskey: Application Key set
- devaddr: End-Device Address set
- deveui: End-Device Identifer set
- devmultiskey: End-Device Multicast Session Key set
- nwkmultiskey: Network Multicast Session Key set
- nwkskey: Network Session Key set
• mcast: Multicast State
• mcastappskey: Multicast Application Session Key
• mcastdevaddr: Multicast End Device Address
• mcastnwkskey: Multicast Network Session Key
• nwkskey: Network Session Key
• rx2 parameters: RX Window 2 parameters
- freq: Frequency
- status: Status
• upctr: Uplink Frame Counter
Example: mac save// Saves the LoRaWAN Class A protocol
Response: ok
The network can issue a certain command (Duty Cycle Request frame with parameter
255) that would require the RN2483 module to go silent immediately. This mechanism
disables any further communication of the module, effectively isolating it from the
network. Using mac forceENABLE after this network command has been received
restores the module’s connectivity by allowing it to send data.
Example: mac forceENABLE// Disables the Silent Immediately state.
Note:The silent immediately status bit of the MAC status register
indicates the device has been silenced by the network. Refer to Figure
2-1: “MAC Status bit-Mapped Register (1)”.
2.4.6mac pause
Response: 0 – 4294967295 (decimal number representing the number of milliseconds
the mac can be paused)
This command pauses the LoRaWAN stack functionality to allow transceiver (radio)
configuration. Through the use of mac pause, radio commands can be generated
between a LoRaWAN Class A protocol uplink application (mac tx command), and the
LoRaWAN Class A protocol Receive windows (second response for the mac tx
command). This command will reply with the time interval in milliseconds that the
transceiver can be used without affecting the LoRaWAN functionality. The maximum
value (4294967295) is returned whenever the LoRaWAN stack functionality is in Idle
state and the transceiver can be used without restrictions. ‘0’ is returned when the
LoRaWAN stack functionality cannot be paused.
For example, when operating in LoRaWAN Class C mode, the receiver is continuously
in receive. The mac pause command will return ‘0’ indicating that the LoraWAN stack
cannot be paused.
After the radio configuration is complete, the mac resume command must be used to
return to LoRaWAN protocol commands.
Example: mac pause// Pauses the LoRaWAN stack
functionality if the response is different
from 0.
Note:If already joined to a network, this command MUST be called BEFORE
configuring the radio parameters, initiating radio reception, or transmission.
2.4.7mac resume
Response: ok
This command resumes LoRaWAN stack functionality, in order to continue normal
functionality after being paused.
Example: mac resume// Resumes the LoRaWAN stack functionality.
Note:This command MUST be called AFTER all radio commands have been
issued and all the corresponding asynchronous messages have been
replied.

2.4.8.3mac set ar <state><state>: string value representing the state, either on or off.
Response: ok if state is valid
invalid_param if state is not valid
This command sets the state of the automatic reply. By enabling the automatic reply,
the module will transmit a packet without a payload immediately after a confirmed
downlink is received, or when the Frame Pending bit has been set by the server. If set
to OFF, no automatic reply will be transmitted.
Example: mac set ar on// Enables the automatic reply process
inside the module.
Note:The RN2483 module implementation will initiate automatic transmissions
with no application payload if the automatic reply feature is enabled and the
server sets the Frame Pending bit or initiates a confirmed downlink
transmission. In this case, if all enabled channels are busy due to duty cycle
limitations, the stack will wait for the first channel that will become free to
transmit. The user will not be able to initiate uplink transmissions until the
automatic transmissions are done.
2.4.8.4mac set bat <level><level>: decimal number representing the level of the battery, from 0 to 255. ‘0’
means external power, ‘1’ means low level, 254 means high level, 255

2.5.1radio rx <rxWindowSize>
<rxWindowSize>: decimal number representing the number of symbols (for LoRa
modulation) or time-out (in milliseconds, for FSK modulation) that
the receiver will be opened, from 0 to 65535. Set
<rxWindowSize> to ‘0’ in order to enable the Continuous
Reception mode. Continuous Reception mode will be exited once
a valid packet is received.
Response: this command may reply with two responses. The first response will be
received immediately after entering the command. If the command is valid
(ok reply received), a second reply will be received after the reception of a
packet or after the time-out occurred.
Response after entering the command:
• ok – if parameter is valid and the transceiver is configured in Receive mode
• invalid_param – if parameter is not valid
• busy – if the transceiver is currently busy
Response after the receive process:
• radio_rx <data> – if reception was successful, <data>: hexadecimal value
that was received;
• radio_err – if reception was not successful, reception time-out occurred
Example: radio rx 0// Puts the radio into continuous Receive mode.
Ensure the radio Watchdog Timer time-out is higher than the Receive window size.
Note:The mac pause command must be called before any radio transmission
or reception, even if no MAC operations have been initiated before.
Note:When transmitting FSK packets, the payload and the 2-byte CRC is
whitened by being XORed with a pseudorandom sequence generated by
an LFSR with the polynomial X
reverted on reception so that it is transparent to the user.

2.5.2radio tx <data>
<data>: hexadecimal value representing the data to be transmitted, from 0 to 255
bytes for LoRa modulation and from 0 to 64 bytes for FSK modulation.
Response: this command may reply with two responses. The first response will be
received immediately after entering the command. If the command is valid
(ok reply received), a second reply will be received after the effective
transmission.
Response after entering the command:
• ok – if parameter is valid and the transceiver is configured in Transmit mode
• invalid_param – if parameter is not valid
• busy – if the transceiver is currently busy
Response after the effective transmission:
• radio_tx_ok – if transmission was successful
• radio_err – if transmission was unsuccessful (interrupted by radio Watchdog
Example: radio tx 48656c6C6F // Transmits a packet of
[0x48][0x65][0x6c][0x6C][0x6F];
Hello.
Note:In order to meet ETSI regulations in the given frequency bands, the radio
has to use either Listen Before Talk (LBT) + Adaptive Frequency Agility
(AFA) or duty cycle limitations. By issuing the radio tx <data>
command the module does not perform LBT before transmission, thus the
user has to make sure that duty cycle limits are not violated. For more
information on duty cycle limits please check the EN 300 220-2 v2.4.1
standard.
Note:The mac pause command must be called before any radio transmission
or reception, even if no MAC operations have been initiated before.

Response: ok if state is valid
invalid_param if state is not valid
This command will enable or disable the CW mode on the module. CW mode allows
the user to put the transceiver into Transmission mode to observe the generated signal.
By altering the settings for the radio the user can observe the changes in transmissions
levels.
Example: radio cw on
Note:Please note that using radio cw off resets the module, this command
being semantically identical to sys reset.

Chapter 3. Bootloader Usage
This chapter describes the operation of the bootloader on the RN2483 LoRa modules.
The bootloader can be used to upgrade the firmware in the field without requiring the
use of a hardware programming tool.
3.1BOOTLOADER HOSTS
The bootloader requires a host computer to control the bootloader operations and provide the firmware file to be programmed into the RN2483 module. The host computer
can either be the embedded host microcontroller in the end product, or a PC can be
used. If the product's embedded microcontroller will be used with the bootloader, the
user must implement the bootloader protocol described later in this section. If a PC is
being used as a host for the RN2483 module, for example during development,
Microchip has a bootloader host application that can be used.
The bootloader on the RN2483 module is based on the Microchip's standard 8-bit
UART bootloader. This document describes the specifics of the RN2483 bootloader
implementation.
The RN2483 module bootloader is invoked automatically when the firmware becomes
corrupted, or if the firmware is erased.
To invoke the RN2483 bootloader to update the firmware, the RN2483 system command to erase the firmware needs to be executed. For more information, refer to
2.3.3 “sys eraseFW”.
RN2483 LoRa TECHNOLOGY MODULE
COMMAND REFERENCE USER’S GUIDE
Note:Once the sys eraseFW command is executed, the RN2483 module
becomes unresponsive to all Microchip LoRa Stack commands. The
RN2483 module will be in Bootloader mode, and will remain in Bootloader
mode until new firmware is successfully installed. The RN2483 firmware
must be programmed into the module using the bootloader, or a hardware
programming tool.
For additional information on bootloader usage, refer to 3.5 “Bootloader Usage
The RN2483 bootloader is similar to other Microchip bootloaders. This section
describes the specifics of RN2483 bootloader protocol. Ta bl e 3 -1 provides the list of
commands required to update the RN2483 module firmware.The Microchip standard

8-bit UART bootloader has a common command protocol for all commands.
There are two multi-byte fields common to all commands. These are the Length field,
and the Address field. These values are sent in little-endian format. This means that
the low-order byte (Least Significant Byte) is sent first, and the high-order byte (Most
Significant Byte) is sent last.
Write Operations
When an Erase or Write command is issued, the two key fields must be supplied with
correct values. For read operations, they key fields are not used. The values of the keys
are always:
• Key1 = 0x55
• Key2 = 0xaa
General Differences from 8-Bit Bootloader
• Module bootloader only uses the first-length byte and ignores the second-length
byte in all commands. The protocol still requires that the second length-byte be
sent, but the bootloader ignores this value.
• Each command is preceded by 0x55 (ASCII ‘U’); this is used for auto-baud
detection.
3.3RN MODULE BOOTLOADER COMMANDS
The command format has an initial byte of 0x55, and the second byte of the length field
(MSB) is always 0x00.
DS40001784G-page 56 2015-2018 Microchip Technology Inc.
Bootloader Usage
The typical bootloader response to commands starts with repeating back the command
and follows with a command specific response. Exceptions to this format are described
in the commands in which they occur.
This command writes data into the Flash memory. The length field can range from 0 to
255. This determines the number of bytes written to Flash. The Write Flash command
does not erase any Flash memory before writing data; therefore, this command should
be preceded by an Erase Flash command for proper operation.
Response:
<write flash command><Status>
Status is either a ‘0’ indicating that the command failed, or a ‘1’ indicating the
command was successful.
Note:The data bytes are not returned in the command response. Only the write
This command erases one or more blocks of Flash memory, starting at address
Address. The Blocks field can range from 0 to 255. The 1-255 value of the Blocks field
represents the number of blocks to erase. If the Blocks field is ‘0’, the bootloader will
erase 256 blocks.
Response:
<erase flash command><Status>
Status is either a ‘0’ indicating that the command failed, or a ‘1’ indicating the
This command returns the checksum calculated over the Flash memory range
beginning at Address for a length of Len bytes. If Len is odd, 1 is added to make Len
even.
The checksum algorithm treats the Flash memory as an array of 16-bit values during
the calculation, which is not performed byte by byte. In MPLAB X, this is known as
Checksum Algorithm 2.
Response:
<calculate and ret urn checksum command (modified)><CSumLSB>
<CSumMSB>
Note:The Len field in the returned calculate and return checksum com-
mand is set to 0x00 in the reply.
Status is either a ‘0’ indicating that the command failed, or a ‘1’ indicating the
command was successful.
This command does not generate a response and immediately performs a software
reset of the module. If the firmware update was successful, the RN2483 firmware will
execute after the reset. If the firmware was not updated or the update failed, the bootloader will execute after the reset.

3.5BOOTLOADER USAGE EXAMPLES
3.5.1Using Bootloader with an Embedded Host
This section provides an overview of the requirements to use an embedded host microcontroller to control the bootloader.
The end user is responsible for implementing application software for an embedded
bootloader host. The bootloader communication protocol is described in
3.2 “Protocol”.
The following is a list of the suggested steps that the bootloader host application should
perform:
Erasing the RN2483 firmware:
• Check the existing firmware version
- sys get ver (2.3.6.1)
• Erase the existing firmware
- sys eraseFW (2.3.3)
The RN2483 module will automatically reset, and execute the bootloader.
Installing new firmware using the bootloader:
• Check the bootloader firmware version
- Get Version Info (Table 3-4)
• Erase all of the Flash from address 0x300 to 0xFFFF
- Erase Flash (Ta ble 3 -7) – The erase command must be issued (4)
times to erase all the blocks of Flash program memory
• Write the new blocks of firmware. Repeat until all blocks have been written
- Write Flash (Ta b le 3 - 6)
• Request the firmware checksum from the bootloader. Compare to the value
calculated by the host application
- Calculate and return Flash checksum (Ta b le 3 -8 )
• Reset the device (Ta b le 3 - 9)
Bootloader Usage
3.5.2Using Bootloader with a PC Host
This section describes using the Microchip LoRa Development Utility software
application on a PC to update the firmware of the RN2483 module.
As of this writing, the current version of the Microchip LoRa Development Utility application for the PC is “LoRaDevUtility.jar” version 1.0.1. This can be found in the
LoRa Development Suite Software on the Microchip website (www.microchip.com).
Connect the UART on the RN2483 to a COM port on the PC. For example, the Microchip MCP2221 USB to Serial Breakout Module (ADM00559) can be used. For information on connecting the UART on the RN2483 module, refer to the RN2483, Low-Power
Long-Range LoRa
Note:The LoRaDevUtility supports other Microchip products and was intended
for other purposes beyond the bootloader functionality. This document only
describes the bootloader for Device Firmware Update (DFU) function as
used by the RN2483 modules.
3.5.2.1UPDATE RN2483 MODULE FIRMWARE USING LORADEVUTILITY
1. Launch the LoRaDevUtility.jar application.
2. The LoraDevUtility probes all the available serial ports on the PC. The left win-
dow pane lists all of the Microchip LoRaWAN devices found.

operation may take 20 seconds or more depending on the speed of the
connection.
Note:Sometimes the communication link may be disconnected after the
sys eraseFW command, and before the bootloading operation completes.
If the messages Device: COMn Bootloading started, or Device: COMn Bootloading Successful do not appear, additional steps must
be performed. The RN2483 module is in Bootloader mode and will remain
in Bootloader mode until new firmware is successfully installed. If the bootloading process does not complete, follow the steps in
3.5.2.2 “LoRaDevUtility - Boot Load Recover” to complete the
bootloading operation.
