In the world of the Internet of Things (IoT), regularly updating firmware is crucial for device security, functionality, and longevity. LoRaWAN® provides an efficient method for distributing firmware updates wirelessly and simultaneously to multiple devices via Firmware Update Over-The-Air (FUOTA).

With the LoRaWAN® Application Protocols Module from STACKFORCE, implementing FUOTA becomes even easier and more flexible. This module is stack-independent and is easy to integrate, making it ideal for a wide range of IoT applications.

What is FUOTA?

FUOTA enables firmware updates to be distributed over the LoRaWAN® network without physical access to the devices. This is especially beneficial for devices deployed in remote or hard-to-reach locations, or in large numbers.

Benefits of FUOTA:

  • Scalability: Simultaneous updates to many devices.
  • Efficiency: Reduced energy consumption through multicast transmissions.
  • Security: Authentication and integrity checks for firmware files.
  • Cost Savings: Less need for on-site maintenance.

6 Steps to Successful FUOTA

  1. Device Identification: Select the devices to be updated and group them into multicast groups.
  2. Firmware Generation: Create the new firmware file for the target devices.
  3. Distribution: Transfer the firmware to the multicast group.
  4. Authentication: Each device verifies the firmware signature.
  5. Installation: Devices install the new firmware.
  6. Status Reporting: Devices report whether the update was successful or not.

Core Components of the FUOTA Process

  • Clock Synchronization
    Synchronizes the internal clocks of the devices with the network to enable coordinated reception times for multicast messages.
  • Remote Multicast Setup
    Allows the creation and management of multicast groups, including the definition of sessions and assignment of devices.
  • Fragmented Data Block Transport
    Splits the firmware into smaller fragments and implements error correction mechanisms to ensure reliable transmission.
