report data on Timing Mode.

3.5 Advanced Settings
3.5.1 Threshold Settings Geofence:
When GNSS positioning is enabled, AT101 supports to set a round geofence range. AT101 will detect whether the location is within the radius range of preset coordinates. If the device is out of the range, it will upload threshold alarm packets; if it returns back to the range, it will upload a threshold alarm dismiss packet.
Note: after Geofence is enabled, it only works after next positioning.

Note: The alarm is activated when the device is located 10 meters further than the set radius value; the alarm is dismiss when the device is located 10 meters closer than the set radius value.
Alarm Reporting Interval| After the threshold is triggered, the device will locate according to this
reporting interval to detect if the threshold is still triggered.
Alarm Reporting Times| Alarm packet reporting times if the threshold is still triggered.

Tilt Threshold:
When the offset angle of any axis is more than 20° based on initial surface, the device will upload a tilt alarm packet; when offset angle of all 3 axis is within 20° based on initial surface, the device will upload an alarm dismiss packet.

packets.
Setting| Click to set current position of device as initial position.
Clear| Change the initial position back to (0.00°, 0.00°, -90.00°)

Note: after writing Setting or Clear configuration, click Read to read the device to check if the initial position changes successfully.

3.5.2 Data Storage
AT101 sensor supports storing 1,300 data records locally and export data via ToolBox App. The device will record the GNSS data according to reporting interval even not joining to network. It will not record Wi-Fi scanning data locally.

1. Go to Device > Status of ToolBox App to click Sync to sync the device time.
   

2. Go to Device > Setting > General Settings of ToolBox App to enable data storage feature.

3. Go to Device > Maintenance of ToolBox App, click Export, then select the data time period and click Confirm to export data. The maximum export data period on ToolBox App is 14 days.
   

4. Click Data Cleaning to clear all stored data inside the device.

3.5.3 Data Retransmission
AT101 sensor supports data retransmission to ensure the network server can get all data even if network is down for some times. There are two ways to get the lost data:

• Network server sends downlink commands to enquire the historical data for specifying time range, refer to section 5.3.
• When network is down if no response from LinkCheckReq MAC packets for a period of time, the device will record the network disconnected time and re-transmit the lost data after device re-connects the network.

Here are the steps for retransmission:

1. Go to Device > Setting > General Settings to enable data storage and data retransmission feature.

2. Go to Device > Settings > LoRaWAN Settings to enable rejoin mode feature and set the number of packets sent. Take below as example, the device will send LinkCheckReq MAC
   packets to the network server regularly to check if the network is disconnected; if there is no response for 8+1 times, the join status will change to de-active and the device will record a data lost time point(the time to join the network).

3. After the network connected back, the device will send the lost data from the point in time when the data was lost according to the data re-transmission reporting interval.
   Note:

1. If the device is reboot or re-powered when data retransmission is not completed, the device will re-send all retransmission data again after device is reconnected to the network.
2. If the network is disconnected again during data retransmission, it will only send the latest disconnection data.
3. The retransmission data format is started with “20ce”, please refer to section 5.3.
4. Data retransmission will increase the uplinks and shorten the battery life.

5.3 Historical Data Enquiry
AT101 supports sending downlink commands to enquire historical data for specified time point or time range. Before that, ensure the device time is correct and data storage feature was enabled to store the data.
Command format:

bytes), Unix timestamp
fd| 6d (Stop query data report)| ff
ff| 6a (Report Interval)| 3 Bytes, Byte 1: 01
Byte 2: interval time, unit: s,
range: 30~1200s (60s by default)

Reply format:

01: time point or time range invalid
02: no data in this time or time range
20| ce (Historical Data)| Data time stamp (4 Bytes) + Longitude (4
Bytes)+ Latitude (4 Bytes)

Note:

1. The device only uploads no more than 300 data records per range enquiry.
2. When enquiring the data in time point, it will upload the data which is the closest to the search point within the reporting interval range. For example, if the device’s reporting interval is 10 minutes and users send command to search for 17:00’s data, if the device find there is data stored in 17:00, it will upload these data. If not, it will search for data between 16:50 to 17:10 and upload the data which is the closest to 17:00.

Example:

1. Enquire historical data between 2023/6/15 15:45:00 to 2023/6/15 15:55:00.
   fd6c 7cc18a64 d4c38a64

   Channel| Type| Value
   fd| 6c (Enquire data in time range)| Start time: 7cc18a64=> 648ac17c =
