1562 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.

1631
1632 LHT65N supports AT Command set.User can use a USB to TTL adapter plus the Program Cable to
1633
1634 connect to LHT65 for using AT command, as below.

1649 In PC, User needs to set serial tool(such as **putty**, SecureCRT) baud rate to **9600** to access to
1650
1651 access serial console for LHT65N. The AT commands are disable by default and need to enter
1652
1653 password (default:**123456**) to active it. Timeout to input AT Command is 5 min, after 5-minute,
1654
1655 user need to input password again. User can use AT+DISAT command to disable AT command
1656
1657 before timeout.
1658
1659 Input password and ATZ to activate LHT65N,As shown below:
