Ex2: Downlink payload: 0x0701 // AT+MQOS=1

3.9 Clock Logging and Historical Records

Sometimes when we deploy lots of end nodes in field. We want all sensors sample data at the same time, and upload these data together for analyze. In such case, we can use clock loging feature.

We can use this command to set the start time of data recording and the time interval to meet the requirements of the specific collection time of data.

AT command: AT+CLOCKLOG=a,b,c,d

a: 0: Disable Clock logging. 1: Enable Clock Logging

b: Specify First sampling start second: range (0 ~~ 3599, 65535) // Note: If parameter b is set to 65535, the log period starts after the node accesses the network and sends packets.

c: Specify the sampling interval: range (0 ~~ 255 minutes)

d: How many entries should be uplink on every TDC (max 32)

📘 Note To disable clock recording, set the following parameters: AT+CLOCKLOG=1,65535,0,0

Example:

AT+CLOCKLOG=1,65535,1,5

After the node sends the first packet, data is recorded to the memory at intervals of 1 minute. For each TDC uplink, the uplink load will include: battery information + the last 5 memory records (payload + timestamp).

📘 Note Users need to synchronize the server time before configuring this command. If the server time is not synchronized before this command is configured, the command takes effect only after the node is reset.

Downlink command: 0x08

Format: Command Code (0x08) followed by 5 bytes.

Example 1: Downlink Payload: 08 01 FFFF 0F 08 // Set SHT record time: AT+CLOCKLOG=1,65535,15,8 Example 2: Downlink Payload: 08 01 04B0 0F 08 // Set SHT record time: AT+CLOCKLOG=1,1200,15,8

Format: Command Code (0x13) followed by 1 byte.

Example: Downlink Payload: 13 0A// AT+CSQTIME=10

3.12 Factory data reset

Two different restore factory Settings configurations.

AT command:

• AT+FDR// Reset Parameters to Factory Default.
• AT+FDR1// Reset parameters to factory default values except for passwords.

3.13 Set CoAP option

This command sets the connection parameters of the COAP.

AT command:

• AT+URI1 // CoAP option name, CoAP option length, "CoAP option value"
• AT+URI2 // CoAP option name, CoAP option length, "CoAP option value"
• AT+URI3 // CoAP option name, CoAP option length, "CoAP option value"
• AT+URI4 // CoAP option name, CoAP option length, "CoAP option value"

Example:

• AT+URI1=11,38,"i/faaa241f-af4a-b780-4468-c671bb574858"

3.14 Example Query saved historical records

• AT command: AT+CDP

This command can be used to search the saved history, recording up to 32 groups of data, each group of historical data contains a maximum of 100 bytes.

3.15 Uplink log query

• AT command: AT+GETLOG

This command can be used to query upstream logs of data packets.

3.16 Add External Sensors

Use AT+WSS=a,b,c:

Parameter	Sensor	Values
a	Wind speed and direction	0: disable; 1: enable
b	Soil sensor, address 1	0: disable; 1: enable
c	Soil sensor, address 2	0: disable; 1: enable

Example: AT+WSS=1,1,1 enables all optional sensors. Soil sensors must use addresses 01 and 02.

Downlink Payload: 20 01 01 01 // AT+WSS=1,1,1

3.17 Wind Speed Acquisition Duration

Feature: Get or set the real time wind speed

AT Command: AT+WINDT

Command Example	Function	Response
AT+WINDT=?	Get the current sample duration	20(unit: second) OK Default 20 seconds
AT+WINDT=10	Set the current sample duration (Max: 255s; Min: 0s)	OK Get the current sample duration to 10 seconds

Downlink Command: 0x21

Format: Command Code (0x21) followed by 1 bytes time value.

If the downlink payload = 2114, this indicates setting the terminal node's wind speed sampling duration to 0x14 = 20 (seconds), with the type code being F1.

• Example 1: Downlink Payload: 2114 // Wind speed sampling duration is set to 20 (seconds)
• Example 2: Downlink Payload: 213C // Wind speed sampling duration is set to 60 (seconds)

3.18 Wiring Method

Note: Since the WSC2-Compact-NS uses the I2C protocol as its default sensor communication protocol, but the wind speed and direction sensor, and soil sensor utilize the RS485 protocol, an additional DR-F6C-4 cable must be added to the existing setup.

3.19 Set the downlink debugging mode

Feature: Enable or disable downlink debugging mode. (Since TE platform update, the platform version selection is no longer needed; only downlink debugging can be toggled.)

AT command: AT+DOWNTE

Command Example	Function/Parameters	Response/Explanation
AT+DOWNTE=?	Get current Settings	0,0 (default) OK
AT+DOWNTE=0,a	a: Enable/Disable downlink debugging	0: Disable downlink debugging mode. 1: Enable downlink debugging mode (users can view original downlink messages).

(Note: The first parameter is fixed to 0 and only the second parameter is configurable.)

Example:

• AT+DOWNTE=0,1 → Enable downlink debugging mode.
• AT+DOWNTE=0,0 → Disable downlink debugging mode.

Downlink Command:

No downlink commands for feature

3.20 Domain name resolution settings

Feature: Set static DNS resolution IP address.

AT command: AT+BKDNS

Command Example	Function/Parameters	Response/Explanation
AT+BKDNS=?	Get current Settings	1,0,NULL (default) OK
AT+BKDNS=a,b,c	a: Enable/Disable static DNS resolution.	0: Disable static DNS resolution 1: Enable static DNS resolution. The ip address will be saved after the domain name is resolved, if the next domain name resolution fails, the last saved ip address will be used.
	b: Meaningless.	Set to 0.
	c: Set the IP address manually.	The format is the same as AT+SERVADDR. If domain name resolution fails, this ip address will be used directly, if domain name resolution succeeds, parameter c will be updated to the successfully resolved IP address.

Example:

• AT+BKDNS=0,0,NULL //Disable static DNS resolution.
• AT+BKDNS=1,0,NULL // Enable static DNS resolution.
• AT+BKDNS=1,0,3.69.98.183,1883 //Enable static DNS resolution, if domain name resolution succeeds, the node uses the ip address successfully resolved and saves it to parameter c. If the domain name resolution fails, use the manually set ip address: 3.69.98.183 for communication.

Downlink Command:

No downlink commands for feature.
