589 +1. Set [[PNACKMD=1>>||anchor="H4.13AutoSendNone-ACKmessages"]], LHT65N will wait for ACK for every uplink, when there is no LoRaWAN network, LHT65N will store the sensor data, and it will send all messages after the network recovery.

763 -* a) LHT65N will do an ACK check for data records sending to make sure every data arrive server.
764 -* b) LHT65N will send data in **CONFIRMED Mode** when PNACKMD=1, but LHT65N won't re-transmit the packet if it doesn't get ACK, it will just mark it as a NONE-ACK message. In a future uplink if LHT65N gets a ACK, LHT65N will consider there is a network connection and resend all NONE-ACK Message.
