One LoRa modem can communicate with multiple LoRa IO modulesAbout CWT LoRa device wireless communication1.Open air communication distance is about 3KM, distance will be affected by obstructions2.Communication in building, the distance through the wall is about 5-6 layers of wall3.Can setup LoRa communication parameters by config toolCWT-M5-LoRa Features1 Basic Feature2 Technical Specification3 Size4 Package listModule×1, antenna×1, USB cable×1
This is a serial to Ethernet server, used for data transparent transmission.
User can apply it to device networking communication.
Support DHCP, automatically obtain an IP address and query IP address through serial setting protocol, Support DNS function, Set parameters through webpage, Upgrade firmware via network.
User-defined registration package mechanism, check connection status and use as custom packet header.
Across the gateway, switches, routers, Can work in LAN, also can work in the Internet (external network).
