Configurations

Several Kconfig options in Kconfig.cloud control this module’s behavior. The following configuration parameters are associated with this module:

• CONFIG_APP_CLOUD_SHELL: Enables shell support for cloud operations.

• CONFIG_APP_CLOUD_PAYLOAD_BUFFER_MAX_SIZE: Defines the maximum size for JSON payloads sent to the cloud.

• CONFIG_APP_CLOUD_SHADOW_RESPONSE_BUFFER_MAX_SIZE: Sets the maximum buffer size for receiving shadow data.

• CONFIG_APP_CLOUD_CONFIRMABLE_MESSAGES: Uses confirmable CoAP messages for reliability.

• CONFIG_APP_CLOUD_BACKOFF_INITIAL_SECONDS: Starting delay (in seconds) before reconnect attempts.

• CONFIG_APP_CLOUD_BACKOFF_TYPE: Specifies backoff strategy (none, linear, or exponential).

• CONFIG_APP_CLOUD_BACKOFF_TYPE_EXPONENTIAL: Use exponential backoff time. The backoff time is doubled after each failed attempt until the maximum backoff time is reached.

• CONFIG_APP_CLOUD_BACKOFF_TYPE_LINEAR: Use linear backoff time. The backoff time is incremented by a fixed amount after each failed attempt until the maximum backoff time is reached.

• CONFIG_APP_CLOUD_BACKOFF_LINEAR_INCREMENT_SECONDS: If using linear backoff, defines how much time to add after each failed attempt.

• CONFIG_APP_CLOUD_BACKOFF_MAX_SECONDS: Maximum reconnect backoff limit.

• CONFIG_APP_CLOUD_HANDLE_WRONG_SAMPLE_TIMESTAMPS_DROP: Drops samples with invalid timestamps when sending data to the cloud.

• CONFIG_APP_CLOUD_HANDLE_WRONG_SAMPLE_TIMESTAMPS_KEEP: Sends samples with invalid timestamps to the cloud without modification.

• CONFIG_APP_CLOUD_HANDLE_WRONG_SAMPLE_TIMESTAMPS_NOW: Replaces invalid timestamps with the current time before sending to the cloud.

• CONFIG_APP_CLOUD_HANDLE_WRONG_SAMPLE_TIMESTAMPS_NO_TIMESTAMP: Sends samples with invalid timestamps to the cloud with NRF_CLOUD_NO_TIMESTAMP, which makes nRF Cloud assign the timestamp upon reception.

• CONFIG_APP_CLOUD_THREAD_STACK_SIZE: Stack size for the cloud module’s main thread.

• CONFIG_APP_CLOUD_MESSAGE_QUEUE_SIZE: Zbus message queue size.

• CONFIG_APP_CLOUD_WATCHDOG_TIMEOUT_SECONDS: Watchdog timeout for the module’s thread. Must be larger than the message processing timeout.

• CONFIG_APP_CLOUD_MSG_PROCESSING_TIMEOUT_SECONDS: Maximum time allowed for processing a single incoming message.
