1575 == 6.1 How to use AT Command? ==
1576
1577 LHT65N supports AT Command set.User can use a USB to TTL adapter plus the Program Cable to
1578
1579 connect to LHT65 for using AT command, as below.
1580
1581 [[image:image-20220530085651-1.png]]
1582
1583
1584 Connection:
1585
1586 ✓ USB to TTL GND <~-~->GND
1587
1588 ✓ USB to TTL RXD <~-~-> D+
1589
1590 ✓ USB to TTL TXD <~-~-> A11
1591
1592 ✓ USB to TTL 3.3V <~-~-> D-
1593
1594 In PC, User needs to set serial tool(such as **putty**, SecureCRT) baud rate to **9600** to access to
1595
1596 access serial console for LHT65N. The AT commands are disable by default and need to enter
1597
1598 password (default:**123456**) to active it. Timeout to input AT Command is 5 min, after 5-minute,
1599
1600 user need to input password again. User can use AT+DISAT command to disable AT command
1601
1602 before timeout.
1603
1604 Input password and ATZ to activate LHT65N,As shown below:
