80 If T68DL is under the coverage of this LoRaWAN network. T68DL can join the LoRaWAN network automatically. After successfully joining, T68DL will start to measure environment temperature, and start to transmit sensor data to the LoRaWAN server. The default period for each uplink is 20 minutes.

374
375
376 There are two methods:
377
378 (% style="color:blue" %)**Method 1:** (%%)IoT Server sends a downlink LoRaWAN command to [[poll the value>>||anchor="H2.6.4Pollsensorvalue"]] for specified time range.
379
380
381 (% style="color:blue" %)**Method 2: **(%%)Set [[PNACKMD=1>>||anchor="H4.13AutoSendNone-ACKmessages"]], T68DL will wait for ACK for every uplink, when there is no LoRaWAN network, T68DL 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.
382
383
384 (% style="color:red" %)**Note for method 2:**
385
386 * a) T68DL will do an ACK check for data records sending to make sure every data arrive server.
387 * b) T68DL will send data in **CONFIRMED Mode** when PNACKMD=1, but T68DL 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 T68DL gets a ACK, T68DL will consider there is a network connection and resend all NONE-ACK Message.
388
389 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)
