--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.

++* a) LHT65N will do an 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 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.
