1531 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.

1600
1601 LHT65N supports AT Command set.User can use a USB to TTL adapter plus the Program Cable to
1602
1603 connect to LHT65 for using AT command, as below.
1604

1618 In PC, User needs to set serial tool(such as **putty**, SecureCRT) baud rate to **9600** to access to
1619
1620 access serial console for LHT65N. The AT commands are disable by default and need to enter
1621
1622 password (default:**123456**) to active it. Timeout to input AT Command is 5 min, after 5-minute,
1623
1624 user need to input password again. User can use AT+DISAT command to disable AT command
1625
1626 before timeout.
1627
1628 Input password and ATZ to activate LHT65N,As shown below:
