WTS Temperature sensor 28 / 32
 Commands special design for WTS
These commands only valid for WTS, as below:
3.1 SetTransmit Interval Time
Feature: Change LoRaWAN End Node Transmit Interval.
AT Command: AT+TDC
Command Example Function Response
AT+TDC? Show current transmit Interval
30000
OK
the interval is 30000ms = 30s
AT+TDC=60000 Set Transmit Interval
OK
Set transmit interval to 60000ms =
60 seconds
Downlink Command: 0x01
Format: Command Code (0x01) followed by 3 bytes time value.
If the downlink payload=0100003C, it means set the END Node’s Transmit Interval to
0x00003C=60(S), while type code is 01.
 Example 1: Downlink Payload: 0100001E // Set Transmit Interval (TDC) = 30 seconds
 Example 2: Downlink Payload: 0100003C // Set Transmit Interval (TDC) = 60 seconds
3.2 SetExternal Sensor Mode
Feature: Change External Sensor Mode.
AT Command: AT+EXT
Command Example Function Response
AT+EXT=1 Set the working mode to TMP117
AT+EXT=2 Set the working mode to TMP117 and PT100
AT+EXT=3
Set the working mode to photoresistor
photoresistor works: If the sensor goes from black to light, and at the
same time exceeds the set time in the bright area, it will send a packet.
Downlink Command: 0xA2
Total bytes: 2 ~3 bytes
Example:
 0xA201: Set model to TMP117
 0XA202: Set model to TMP117 and PT100
