1542 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.

1611
1612 LHT65N supports AT Command set.User can use a USB to TTL adapter plus the Program Cable to
1613
1614 connect to LHT65 for using AT command, as below.

1629 In PC, User needs to set serial tool(such as **putty**, SecureCRT) baud rate to **9600** to access to
1630
1631 access serial console for LHT65N. The AT commands are disable by default and need to enter
1632
1633 password (default:**123456**) to active it. Timeout to input AT Command is 5 min, after 5-minute,
1634
1635 user need to input password again. User can use AT+DISAT command to disable AT command
1636
1637 before timeout.
1638
1639 Input password and ATZ to activate LHT65N,As shown below:
