--

--Set PNACKMD=1, DS20L will wait for ACK for every uplink, when there is no LoRaWAN network, DS20L will mark these records with non-ack messages and store the sensor data, and it will send all messages (10s interval) after the network recovery.

--a) DS20L will do an ACK check for data records sending to make sure every data arrive server.

--b) DS20L will send data in **CONFIRMED Mode** when PNACKMD=1, but DS20L 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 DS20L gets a ACK, DS20L will consider there is a network connection and resend all NONE-ACK messages.

If server doesn't support this command, it will through away uplink packet with this command, so user will lose the packet with time request for TTN V3 v2 if SYNCMOD=1.**
