Can I access cloud data from my firmware?

ESP RainMaker is primarily designed for cloud-to-device communication. However, you can:

  1. Use Command-Response: Send requests to the cloud and receive responses:

    esp_rmaker_cmd_resp_enable();

    See Command-Response Usage.

  2. Subscribe to MQTT topics: For advanced use cases, subscribe to specific MQTT topics for custom data exchange.

  3. Use REST APIs: Your device can make HTTP requests to RainMaker's REST APIs (requires authentication).
