n the world of IoT (Internet of Things), especially in large-scale LoRaWAN-based deployments, the ability to remotely update firmware is not just a convenience — it’s a necessity. This is where FUOTA (Firmware Update Over The Air) comes into play.
Once thousands of devices are deployed in the field — whether in smart cities, agriculture, or industrial monitoring — retrieving each one for a firmware update is impractical, costly, and time-consuming. In such scenarios, FUOTA becomes the lifeline for maintaining system stability, fixing bugs, and adding new features without on-site intervention.
The Challenges of FUOTA in LoRaWAN
LoRaWAN is known for its low power consumption and long-range communication, but it also comes with constraints:
●Low data rate due to SF (spreading factor) settings
●Maximum payload per packet is limited to 255 bytes
●High packet loss in weak signal environments
These limitations make traditional firmware updates over LoRaWAN inefficient or even impossible without a well-designed solution.
Two Core Bottlenecks of LoRaWAN FUOTA
1Large firmware size leads to low success rate due to packet loss and long transmission time
2Need for packet segmentation and reassembly increases complexity and resource usage
Without a smart and efficient approach, firmware updates can become a major operational burden — especially when dealing with thousands of distributed nodes.
How Manthink Tackles LoRaWAN FUOTA
Since 2017, Manthink has been applying FUOTA at scale in real-world LoRaWAN deployments. Their solution is built on a combination of proprietary technologies:
✅ MPOS Operating System
Manthink’s MPOS is a lightweight, real-time operating system designed with upgradeability in mind. It includes built-in hook mechanisms that allow:
●Updating individual functions
●Adding new tasks or event handlers
●Performing differential upgrades to reduce data size
This modular approach ensures that only the necessary parts of the firmware are updated, not the entire image.
✅ EB Computing Framework
The EB (Embedded Binary) framework enables extreme compression of logic and functionality. Complex features can be represented in just a few hundred or even tens of bytes, making them ideal for low-bandwidth LoRaWAN environments.
✅ Multi-Bin Upgrade Technology
Manthink’s multi-bin technology allows firmware to be split into small segments and reassembled intelligently on the device side. This ensures high reliability, even in unstable or lossy networks.
Manthink Products Supporting FUOTA
All of Manthink’s LoRaWAN products are designed with remote firmware updates in mind:
●OMx22S LoRa Module – supports CJ/T 188, DL/T 645, Modbus, and more
●RDO21 / RDI22 DTU Devices – waterproof and DIN rail-mounted for industrial use
●SE72 Temperature & Humidity Sensor – IP65 rated, 8-year battery life, and remote upgrade support
These devices can be easily managed and upgraded using ThinkLink, Manthink’s LoRaWAN Network Server platform.
ThinkLink: A Free NS Platform for Up to 1,000 Devices
Manthink offers ThinkLink, a fully-featured LoRaWAN Network Server, which supports FUOTA upgrades and is free for up to 1,000 devices. This makes it ideal for small to medium-sized IoT projects looking to get started quickly and efficiently.
Final Thoughts
In any large-scale IoT project, especially those using LoRaWAN, having a reliable FUOTA mechanism is essential. It ensures long-term maintainability, reduces operational costs, and improves user experience.
Manthink’s mature and field-tested FUOTA solution, powered by MPOS, EB framework, and multi-bin technology, is a strong choice for developers and operators looking to deploy and maintain LoRaWAN devices at scale.
