4.5 Advanced Settings
4.5.1 Calibration Settings
ToolBox supports numerical calibration for all items. Go to Device > Settings

Calibration Settings to type the calibration value and save, the device will add the calibration value to raw value, then display and upload the final value.

Besides numerical calibration, ToolBox provides more CO2 calibration methods for AM103(L): Manual Calibration: Put the device in an open outdoor environment for more than 10 minutes and click this button to calibrate the CO2 value.
Restore Factory Calibration: Clean the manual calibration and turn back to factory calibration.
Auto Background Calibration: When enabled, keep the device work in a well- ventilated environment for 7 days, then disable the calibration.

4.5.2 Threshold Settings
Go to Device > Settings > Threshold Settings to enable and configure the temperature and CO2 threshold settings.
Temperature threshold: it will upload the current data once instantly when temperature is over or below the threshold. Note that when you change the temperature unit, please re-configure the threshold.

CO2 threshold: it supports defining Excellent, Polluted and Bad threshold for traffic light and screen alarms. Besides, when it exceeds the Bad threshold, AM103(L) will upload the current data once instantly.

4.5.3 Data Storage
AM103(L) supports storing 640 data records and AM102(L) supports storing 1280 data records locally and exports data via ToolBox App. The device will record the data according to reporting interval even not joining network.

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

2.  Go to Device > Maintenance to click Export, then select the data time range and click Confirm to export data. ToolBox App can export last 14 days’ data at most.

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

4.5.4 Data Retransmission
AM100(L) series supports data retransmission to ensure 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, see section 6.4;
• 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 data retransmission:

1. Ensure the device time is correct (see section 4.3);

2. Enable data storage feature and data retransmission feature;

3. 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  isconnected; 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).

4. 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 reporting interval.

Note:

1. If the device is rebooted 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 see section 6.4.
4. Data retransmission will increase the uplinks and shorten the battery life.

4.6 Maintenance
4.6.1 Upgrade

1. Download firmware from Milesight official website to your smartphone.
2. Open ToolBox App and click “Browse” to import firmware and upgrade the device.

Backup is allowed only for devices with the same model and LoRaWAN® frequency band.

1. Go to Template page on the App and save current settings as a template. You can also edit the template file.
2. Select one template file that saved in the smartphone and click Write, then attach it to another device to write configuration.

Note: Slide the template item to the left to edit or delete it. Click the template to edit the configurations.

4.6.3 Reset to Factory Default
Please select one of following methods to reset device:
Via Hardware: Hold on power button for more than 10s.
Via ToolBox App: Go to Device > Maintenance to click Reset, then attach smart phone with NFC area to device to complete reset.

Installation

6.4 Historical Data Enquiry
AM100(L) series sensors support 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 2-3: 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

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 closest to the search point within the reporting interval range. For example, if the device 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 this data; if not, it will search for data between 16:50 to 17:10 and upload the data which is closest to 17:00.

Example:

1. Enquire historical data between 2023/02/15 10:00:54 to 2023/02/15 11:45:40.
