1565 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.

1634
1635 LHT65N supports AT Command set.User can use a USB to TTL adapter plus the Program Cable to
1636
1637 connect to LHT65 for using AT command, as below.

1652 In PC, User needs to set serial tool(such as **putty**, SecureCRT) baud rate to **9600** to access to
1653
1654 access serial console for LHT65N. The AT commands are disable by default and need to enter
1655
1656 password (default:**123456**) to active it. Timeout to input AT Command is 5 min, after 5-minute,
1657
1658 user need to input password again. User can use AT+DISAT command to disable AT command
1659
1660 before timeout.
1661
1662 Input password and ATZ to activate LHT65N,As shown below:
