# Optional auto reprovisioning mode
# ------------------------------------

# This property specifies the conditions under which the device attempts to
# automatically reprovision with the cloud. It is ignored if the device has
# been provisioned manually. One of the following values can be set:
# Dynamic:          Reprovision when the device detects that it may have
#                   been moved from one IoT Hub to another. This is the default.
# AlwaysOnStartup:  Reprovision when the device is rebooted or a crash causes
#                   the daemon(s) to restart.
# OnErrorOnly:      Never trigger device reprovisioning automatically.
#                   Device reprovisioning only occurs as fallback, if the device
#                   is unable to connect to IoT Hub during identity provisioning
#                   due to connectivity errors. This fallback behavior is implicit
#                   in Dynamic and AlwaysOnStartup modes as well.

# Cloud Timeout and Retry Behavior
# ==============================================================================
#
# These settings control the timeout and retries for cloud operations, such as
# communication with DPS during provisioning or IoT Hub for module identity creation.
#
# cloud_timeout_sec is the deadline (in seconds) for a network request (such as
# an HTTP request) to the aforementioned cloud services. A response from the cloud
# must be received before this deadline, or the request will fail as timed out.
#
# cloud_retries controls how many times a request may be retried should it fail.
# The client will always send at least one attempt, so its value will be the number
# of retries after the first attempt should that fail (i.e. cloud_retries = 2
# means that the client will make a total of 3 attempts).
#
# cloud_timeout_sec = 10
# cloud_retries = 1
