3.5.4 Data Retransmission
LEO-S552-THG0 sensor supports data retransmission to ensure network server can get all
data even if network is down for some times. There are two ways to get the lost data:
⚫ Network server sends downlink commands to to enquire the historical data for specifying
time range, see section 5.4;
⚫ When network is down if no response from LinkCheckReq MAC packets for a period of
time, the device will record the network disconnected time and re-transmit the lost data
after device re-connects the network.
Here are the steps for data retransmission:
1. Ensure the device time is correct (see section 3.4);
2. Enable data storage feature and data retransmission feature;
3. Go to Device > Setting > General Settings to enable rejoin mode feature and set the
number of packets sent. Take below as example, the device will send LinkCheckReq MAC
packets to the network server at least every 30 minutes to check if the network is disconnected;
if there is no response for 8 times (8 * 30 mins = 240 mins =4 hours), the device will record a
data lost time point (disconnected time minus 4 hours).
