1544 Feature: LHT65N will wait for ACK for each uplink, If LHT65N doesn't get ACK from the IoT server, it will consider the message doesn't arrive server and store it. LHT65N keeps sending messages in normal periodically. Once LHT65N gets ACK from a server, it will consider the network is ok and start to send the not-arrive message.

1613
1614 LHT65N supports AT Command set.User can use a USB to TTL adapter plus the Program Cable to
1615
1616 connect to LHT65 for using AT command, as below.

1631 In PC, User needs to set serial tool(such as **putty**, SecureCRT) baud rate to **9600** to access to
1632
1633 access serial console for LHT65N. The AT commands are disable by default and need to enter
1634
1635 password (default:**123456**) to active it. Timeout to input AT Command is 5 min, after 5-minute,
1636
1637 user need to input password again. User can use AT+DISAT command to disable AT command
1638
1639 before timeout.
1640
