1561 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.

1630
1631 LHT65N supports AT Command set.User can use a USB to TTL adapter plus the Program Cable to
1632
1633 connect to LHT65 for using AT command, as below.

1648 In PC, User needs to set serial tool(such as **putty**, SecureCRT) baud rate to **9600** to access to
1649
1650 access serial console for LHT65N. The AT commands are disable by default and need to enter
1651
1652 password (default:**123456**) to active it. Timeout to input AT Command is 5 min, after 5-minute,
1653
1654 user need to input password again. User can use AT+DISAT command to disable AT command
1655
1656 before timeout.
1657
1658 Input password and ATZ to activate LHT65N,As shown below:
