Développement d'une plateforme IoT: Un convertisseur LoRaWAN-TCP pour une efficacité multipliée par 3

Convertisseur LoRaWAN/TCP

The major challenge for the system is to aggregate large data chunks and swiftly send them to the host and master devices. LoRaWAN network type won’t allow sending files heavier than 50 bytes, so that information should be accumulated somewhere else before being sent further, while the M-Bus protocol will slow down the data flow. To exclude these two factors from the equation, our engineers have redesigned an IoT network architecture and created a custom LoRaWAN-TCP protocol bridge that allows transmitting data sent through LoRaWAN to TCP networks that are much faster and capable of delivering heavy files. Every segment of the system is united via such converters. They gather data from the IoT devices related to them and transfer it further via TCP networks by the MQTT protocol. When the data reaches the master devices and the host, it’s operated by high-level software designed for working with MQTT messages.
