1547 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.

1616
1617 LHT65N supports AT Command set.User can use a USB to TTL adapter plus the Program Cable to
1618
1619 connect to LHT65 for using AT command, as below.

1634 In PC, User needs to set serial tool(such as **putty**, SecureCRT) baud rate to **9600** to access to
1635
1636 access serial console for LHT65N. The AT commands are disable by default and need to enter
1637
1638 password (default:**123456**) to active it. Timeout to input AT Command is 5 min, after 5-minute,
1639
1640 user need to input password again. User can use AT+DISAT command to disable AT command
1641
1642 before timeout.
1643
1644 Input password and ATZ to activate LHT65N,As shown below:
