1558 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.

1627
1628 LHT65N supports AT Command set.User can use a USB to TTL adapter plus the Program Cable to
1629
1630 connect to LHT65 for using AT command, as below.
1631

1642
1643 ✓ USB to TTL 3.3V <~-~-> D-
1644
1645 In PC, User needs to set serial tool(such as **putty**, SecureCRT) baud rate to **9600** to access to
1646
1647 access serial console for LHT65N. The AT commands are disable by default and need to enter
1648
1649 password (default:**123456**) to active it. Timeout to input AT Command is 5 min, after 5-minute,
1650
1651 user need to input password again. User can use AT+DISAT command to disable AT command
1652
1653 before timeout.
1654
1655 Input password and ATZ to activate LHT65N,As shown below:
