  There are two methods:
--1.  IoT Server sends a downlink LoRaWAN command to [[poll the value>>||anchor="H2.6.4Pollsensorvalue"]] for specifying time range.
--1.  Set [[PNACKMD=1>>||anchor="H4.13AutoSendNone-ACKmessages"]], LHT65N will wait for ACK for every uplink, when there is no LoRaWAN network, LHT65N will mark these records with non-ack message and store the sensor data, and it will send all messages (10s interval) after the network recovery. note: a) LHT65N will do ack check for data records sending to make sure every data arrive server. b) LHT65N will send data in CONFIRMED Mode when PNACKMD=1, but it won't re-transmit the same packet , it will just mark it as NONE-ACK and resend after network is detected.
