3.2.13 Configure Network Category to be Searched for under LTE RAT.

Note

By default, the NB-IoT network is turned off, and only the LTE-M network is enabled. If a user needs to use the NB-IoT network, they must enable it themselves.

AT command: AT+IOTMOD=a,b,c

a: 0: Disable eMTC; 1: Enable eMTC

b: 0: Disable NB-IoT; 1: Enable NB-IoT

c: Priority: If both network categories are enabled simultaneously (a=1 and b=1), the device will give priority to the configured category.

• 0: No specific priority. The module will automatically select the network based on local signal quality and availability (e.g., it will camp on LTE-M if the signal is better).
• 1: Give priority to the eMTC (LTE-M) network.
• 2: Give priority to the NB-IoT network.

Examples:

• Ext1: AT+IOTMOD=1,1,2 ----> Both eMTC and NB-IoT are enabled, with priority given to the NB-IoT network.
• Ext2: AT+IOTMOD=1,1,0 ----> Both eMTC and NB-IoT are enabled, with no specific priority. The module automatically selects the network based on signal quality.

5. Clock logging

When deploying multiple end nodes in the field, users may want them to sample data at the same time and upload the samples together for analysis. The clock logging feature can be used for this purpose.

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)

Example:

AT+CLOCKLOG=1,65535,1,8

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 8 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.

AIS01-FB uses the nRF9151-NGFF module. Access to modem AT commands depends on the interface supported by the installed firmware.

See NRF9151-NGFF AT Command set

9.2 General Manual for -FB , -FS models

Users can follow the instructions in this link to see how to configure to connect to different servers.

9.3 Why is there no LED response when I press the button on the solar panel model?

Note: This section applies only to the related AIS01-FS solar-powered model, not the battery-powered AIS01-FB.

If the LED does not light up when you press the button, it may be because the battery has entered protection mode.

Solution: To reactivate the battery, simply expose the solar panel to direct sunlight.

For more details, please refer to: Battery Protection State (Apply to Solar Panel + Li-ion battery)

9.4 Does this device support GPS positioning?

Yes. This device supports GPS function and can report latitude and longitude coordinates in the uplink payload.

If your camera is running a firmware version earlier than 1.3.4, please check the camera firmware update instructions for the appropriate "Original firmware." For specific update steps, please refer to Update Firmware for the AI Sensors

9.6 Appendix I: Field Installation Photo

Step1:

Find a water meter, install the AIS Sensor on the water meter fixture and install it on the water meter

The following is a comparison of before and after installation:

Note: When the ambient brightness is too high, you can use a cover (such as cardboard) to block other light sources (such as the sun, electric lights) to prevent light reflections from causing the AIS sensor to read inaccurate values.

Step2:

Calibrate the AIS Sensor so that it can accurately read the water meter value.

Step3:

Choose a suitable location to install AIS01-FB. The overall installation is shown below.

Get image data
