2) The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange
value, the device reports according to MinTime interval. If the data variation is not greater than the last data reported,
the device reports according to MaxTime interval.
3) We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the device wakes up
frequently and the battery will be drained soon.
4) Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime interval,
another cycle of MinTime/MaxTime calculation is started.
6. Restore to Factory Setting
The device saves data including network key information, configuration information, etc. To restore
to factory setting, users need to execute below operations.
1. Press and hold both keys for 5 seconds till the green indicator flashes and then release; LED
flashes quickly 20 times.
2. The device will enter off mode by default setting after restoring to factory setting. Press function
key to turn on and join a new LoRa network.
Note: The device operation of turning off is the same as the device restore factory settings.
7. Sleeping Mode
The device is designed to enter sleeping mode for power-saving in some situations:
(A) While the device is in the network → the sleeping period is one hour. (During this period,
if the reportchange is larger than setting value, it will wake up and send a data report).
(B) When it is not in the network → The device will enter sleeping mode and wake up every
15 seconds to search a network to join in the first two minutes. After two minutes, it will wake
up every 15 minutes to request to join the network.
If it’s at (B) status, to prevent this unwanted power consumption, we recommend that users remove
the batteries to power off the device.
Note:
Min Interval for the following single programming is subject to real order.
8. Low Voltage Alarming
The operating voltage threshold is 2.4V. If the voltage is lower than 2.4 V, RA02C will send a
low-power report to the Lora network.
