The following Kconfig options set in the prj.conf file control sampling and
transmission frequency:
CONFIG_APP_SAMPLING_INTERVAL_SECONDS=600 # Default: 10 minutes
CONFIG_APP_STORAGE_INITIAL_THRESHOLD=1 # Default: 1 item
Sensors and location are sampled and stored at the interval set by the
CONFIG_APP_SAMPLING_INTERVAL_SECONDS Kconfig option. Buffered data is sent to the cloud
when the number of stored items reaches
CONFIG_APP_STORAGE_INITIAL_THRESHOLD.
You can adjust these values at runtime using the nRF Cloud device shadow. See the Configuration guide for details.
Impact: Using longer intervals between operations and increasing the storage threshold results in fewer network connections and leads to lower power consumption.
Ensure that the PSM Periodic TAU interval is set reasonably longer than the
expected cloud upload cadence (sampling interval * storage threshold) to avoid waking the modem up too often for
network maintenance.
