MQTT-based Device Connection¶
EnOS Cloud provides a device side SDK for MQTT protocol-based device-side development.
If the provided MQTT SDK cannot meet your needs, you can develop a custom device-side SDK according to EnOS device protocol provided for you in this section to establish an MQTT-protocol-based data transfer channel between the device and EnOS.
