EdgeBus is a low power event driven virtual machine framework designed by Manthink for IoT edge devices operating on resource constrained MCUs. It provides a unified mechanism for data acquisition, protocol parsing, data encapsulation, uplink transmission and firmware upgrade over LPWAN networks such as LoRaWAN. EdgeBus solves essential system challenges including version management, remote FUOTA, network collision avoidance and field maintenance. At its core, EdgeBus introduces a dual event mechanism consisting of periodic Query Events and LoraUp Events, enabling an automated pipeline from sensor data collection to reliable long range wireless transmission. With structured development tools, local ADR, maintenance features and FUOTA optimization, EdgeBus offers a scalable and maintainable solution for large scale IoT deployments with strict power and reliability requirements.
- Overview and Core Concepts
EdgeBus is a lightweight virtual machine running on low power MCUs. Its design goal is to standardize how IoT edge devices collect sensor data, process protocols and transmit uplinks while maintaining extremely low power consumption required by LPWAN applications.
Its core is an event driven architecture, consisting of:
1 Query Event
Periodically interacts with sub devices such as RS 485 / Modbus meters
Performs CRC validation, parsing, byte order handling
Wakes up the MCU only when necessary, minimizing energy consumption
2 LoraUp Event
Periodically assembles processed data and uploads via LoRaWAN
Supports packet segmentation, data streaming and Class A / C switching
Ensures reliable uplink under constrained network conditions
This dual event mechanism builds a highly efficient and fully automated workflow inside a low power IoT terminal.
