5.5.5 Data Retransmission
WT201 supports data retransmission to ensure that the network server can receive all data even
if the network is down for some time. There are two ways to receive the lost data:
Network server sends downlink commands to enquire the historical data for a specified
time range, refer to WT201 Communication Protocol;
When network is down and the device receives no response of LinkCheckReq MAC packets
for a period of time, the device will record during the disconnection period and retransmit
the lost data after the device is reconnected to the network.
Here are the steps of data retransmission:
1. Enable the data storage feature and data retransmission feature.
2. Enable rejoin mode feature and set the number of packets sent in LoRaWAN® settings. For
example, the device will send LinkCheckReq MAC packets to the network server regularly to
check any network disconnection; if there is no response for 8+1 times, the join status will
change to de-active and the device will record a data lost time point (the time it reconnected to
the network).
