546 += Configure LHT65N via AT Command or LoRaWAN Downlink =
547 +
548 +Use can configure LHT65N via AT Command or LoRaWAN Downlink.
549 +
550 +* AT Command Connection: See [[FAQ>>path:#AT_COMMAND]].
551 +* LoRaWAN Downlink instruction for different platforms:
552 +
553 +[[http:~~/~~/wiki.dragino.com/index.php?title=Main_Page#Use_Note_for_Server>>url:http://wiki.dragino.com/index.php?title=Main_Page#Use_Note_for_Server]]
554 +
555 +
556 +There are two kinds of commands to configure LHT65N, they are:
557 +
558 +* **General Commands**.
559 +
560 +These commands are to configure:
561 +
562 +* General system settings like: uplink interval.
563 +* LoRaWAN protocol & radio-related commands.
564 +
565 +They are the same for all Dragino Devices which supports DLWS-005 LoRaWAN Stack(Note~*~*). These commands can be found on the wiki:
566 +
567 +[[http:~~/~~/wiki.dragino.com/index.php?title=End_Device_Downlink_Command>>url:http://wiki.dragino.com/index.php?title=End_Device_Downlink_Command]]
568 +
569 +
570 +
571 +* **Commands special design for LHT65N**
572 +
573 +These commands are only valid for LHT65N, as below:
574 +
575 +
576 +== Set Transmit Interval Time ==
577 +
578 +Feature: Change LoRaWAN End Node Transmit Interval.
579 +
580 +**AT Command: AT+TDC**

582 +|**Command Example**|**Function**|**Response**
583 +|AT+TDC?|Show current transmit Interval|(((
584 +30000
585 +
586 +OK
587 +
588 +the interval is 30000ms = 30s
589 +)))
590 +|AT+TDC=60000|Set Transmit Interval|(((
591 +OK
592 +
593 +Set transmit interval to 60000ms = 60 seconds
594 +)))
595 +
596 +**Downlink Command: 0x01**
597 +
598 +Format: Command Code (0x01) followed by 3 bytes time value.
599 +
600 +If the downlink payload=0100003C, it means set the END Node’s Transmit Interval to 0x00003C=60(S), while type code is 01.
601 +
602 +* Example 1: Downlink Payload: 0100001E ~/~/ Set Transmit Interval (TDC) = 30 seconds
603 +* Example 2: Downlink Payload: 0100003C ~/~/ Set Transmit Interval (TDC) = 60 seconds
