It would leverage the growing eco-system of Xiao expansion boards and the Grove peripherals and would bring an interesting option for IoT.
On the software side, Seeed would port the standard Arduino and the LoRa SX126X to the new board. This would provide a modern alternative to the Moteino boards based on the SX1231h.
As an application layer on top of LoRa, I’ve already used the MQTT-SN implementation Aquila on this project IoT with Sub-1 GHz Sensor Network
- The clients run the An example of an Aquila 2.0 MQTT-SN client implementation for RFM69.
- The bridge is operated by the MQTT-SN Bridge firmware for RFM69 RF module and is plugged into an USB port of the Raspberry Pi.
- The gateway on the Raspberry Pi, is the MQTT-SN gateway for the Aquila 2.0 platform, which transfers the messages between the MQTT-SN bridge and the MQTT broker. It also acts as a port forwarder between the USB port the MQTT-SN bridge is connected to and the gateway.
