Complete Example

Built on the MicroPython environment of the Cassia M2000 gateway, this demo covers three common capabilities — BLE, MQTT, and HTTP — providing a complete reference that developers can use as a starting point for their own APPs.

• BLE: scan advertisements, connect to devices and perform GATT read/write and notification subscription with the cassiablue API.

• MQTT: connect to an MQTT broker asynchronously with micropython-mqtt, subscribe to command topics and publish data.

• HTTP client / server: issue HTTP client requests with aiohttp and expose a local HTTP service (RESTful API and static pages) with microdot.
