• RN2483 EU v1.06 RC4 source code (LoRaWAN specification 1.0.2)
• RN2483 EU v1.06 RC3 source code (LoRaWAN specification 1.0.2)
• RN2903 NA v1.06 RC8 source code (LoRaWAN specification 1.0.2)
• RN2903 NA v1.06 RC7 source code (LoRaWAN specification 1.0.2)
• RN2903 NA v1.06 RC6 source code (LoRaWAN specification 1.0.2)
• RN2903 AS923 v1.06 source code (LoRaWAN specification 1.0.2)
• RN2903 AS923-2 v1.06 source code (LoRaWAN specification 1.0.2)
• RN2903 AS923-3 v1.06 source code (LoRaWAN specification 1.0.2)
• RN2903 AU v1.03 source code (LoRaWAN specification 1.0.1)

It also contains, the following legacy versions of firmware:

• RN2483 EU v1.03 source code (LoRaWAN specification 1.0.1)
• RN2483 EU v1.04 source code (LoRaWAN specification 1.0.1)
• RN2483 EU v1.05 source code (LoRaWAN specification 1.0.2)
• RN2903 NA v1.03 source code (LoRaWAN specification 1.0.1)
• RN2903 NA v1.05 source code (LoRaWAN specification 1.0.2)

And it contains sample cert. applications for the PIC18LF25K50 Host microcontroller:

• Host MCU software used for LoRaWAN Alliance Cert 1.0.1 for the RN2483-pictail/mote
• Host MCU software used for LoRaWAN Alliance Cert 1.0.1 for the RN2903-pictail/mote

• MPLAB X IDE v5.15
• XC8 compiler PRO v1.45 (requires Software License)

Checkout the archive page.

• Open MPLAB X IDE
• Make sure required XC8 compiler is selected by default in Tools -> Options -> Embedded

• Open the requested LoRaWAN project from File -> Open Project (e.g. RN2903NA_1.0.6_RC6\Source)
• Open the project properties from File -> Project Properties
• Apply the requested XC8 compiler version for all the configurations (default, offset, combined)

• For all the 3 configurations (default, offset, combined), make sure XC8 Compiler optimizations options are set for:
  • Favor optimization for: Space
  • Operation mode: PRO

• Select between offset or combined from the selection box

Offset configuration is configuring the project in order to compile the project without the bootloader code Combined configuration is configuring the project in order to compile both the project and the bootloader code

• For combined configuration, the HEX file generated RN2xx3_Parser.production.unified.hex is located into dist/combined/production

• For offset configuration, the HEX file generated RN2xx3_Parser.production.hex is located into dist/offset/production

In addition to the LoRa Transceiver, the RN2xx3 modules integrate a PIC18LF46K22 microcontroller which come with 64kB of Flash and 4kB of RAM. The LoRaWAN Firmware resides into the memory of the PIC18LF46K22 microcontroller.

Requires Programming tool such as MPLAB ICD4 or MPLAB PICkit4

Connect the programming tool to ICSP pins (PCG_INT, PGD_INT, RESET, GND, VCC) as shown in the datasheet.

• Open MPLAB X IPE
• Select PIC18LF46K22 target device
• Select the programming tool
• Click Apply
• Click Connect

• Browse for the required HEX file RN2xx3_Parser.production.unified.hex located into dist/combined/production

• Program the device
• Click Disconnect
• Remove the programming tool connection

To update the RN2483/RN2903 firmware using Bootloader with a Computer Host or with an Embedded Host checkout the Chapter 3. Bootloader Usage of the User Guide

Make sure to use the HEX file RN2xx3_Parser.production.hex located into dist/offset/production
