2. Configure AIS01-LB to connect to LoRaWAN network

2.1 How it works

The AIS01-LB is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the AIS01-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

2.2 ​Quick guide to connect to LoRaWAN server (OTAA)

Following is an example for how to join the TTN v3 LoRaWAN Network. Below is the network structure; we use the LPS8v2  as a LoRaWAN gateway in this example. 

The LPS8v2 is already set to connected to TTN network , so what we need to now is configure the TTN server.

Step 1: Create a device in TTN with the OTAA keys from AIS01-LB.

Each AIS01-LB is shipped with a sticker with the default device EUI as below:

You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

Register the device

Add APP EUI and DEV EUI

Add APP EUI in the application

Add APP KEY

Step 2: Activate AIS01-LB

Press the button for 5 seconds to activate the AIS01-LB.

Green led will fast blink 5 times, device will enter OTA mode for 3 seconds. And then start to JOIN LoRaWAN network. Green led will solidly turn on for 5 seconds after joined in network.

After join success, it will start to upload messages to TTN and you can see the messages in the panel.

2.3 ​Uplink Payload

2.3.1 Device Status, FPORT=5

Users can use the downlink command(0x26 01) to ask AIS01-LB to send device configure detail, include device configure status. AIS01-LB will uplink a payload via FPort=5 to server.

The Payload format is as below.

Example parse in TTNv3

Battery Info:

Check the battery voltage.

Ex1: 0x0B45 = 2885mV

Ex2: 0x0B49 = 2889mV

2.3.2 Timing upload the identified number and time FPORT=2

The uplink payload includes totally 15 bytes. Uplink packets use FPORT=2 and every 20 minutes send one uplink by default. 

Payload Example(FPort=2):0E 1C 66 B5 C1 B0 00 00 7A 15 00 06 BF 6F 01

2.3.2.1 BAT- Battery information

These two bytes of BAT include the battery state and the actual voltage.

Ex：0x0E1C = 3612mV

2.3.2.2 SysTime Current

These four bytes contain the year, month, day, hour, minute, and second of the time.

AI Sensor use Unix TimeStamp format based on:

Users can get this time from the link:  https://www.epochconverter.com/ :

Below is the converter example.

Ex：66B5C1B0=2024-08-09 07:13:52

So, we can use AT+TIMESTAMP=1723187632 or downlink 66B5C1B0 to set the current time 2024 – August -- 9 Friday 07:13:52

2.3.2.3 Integer

These four bytes display the integers in the digital wheel face.

Read table integer：0x00007A15=31253

2.3.2.4 Decimal

These four bytes display decimals on the digital wheel.

Read table decimals：0x0006VF6F/1000000= 0.442223

2.3.2.4 Detection mark

The last byte indicates the camera detection flag. 01 indicates that the camera is connected, and 00 indicates that the camera is not connected.

2.3.3 Image upload function FPORT=3

Because Image is very big , around 3K Bytes per image. To send an image, the AIS01-LB has to use highest DR which support more than 210 bytes for each uplink. AIS01-LB will not auto send the Image in periodically, server can send a downlink command 0x0B 01 to AIS01-LB. When AIS01 get this command , it will starts sending the picture data packets. Each Image will be splited in different packets. System need to combine these packets together to get the final Image.

Example of the first payload(FPort=3):

2.3.3.6 Combined image

Combine each data packet obtained from the platform (note: the first 8 bytes of each data packet need to be deleted before combining)
Then use winhex software to convert to get the image, specific tutorial: Combined image

Below is the text of the integrated data and the image of the converted data:

2.3.4 Clock logging function FPORT=4

FPORT 4 is somewhat similar to FPORT 2 in that how many packets you will receive depends on your CLOCKLOG Settings.

For example:
The AT + CLOCKLOG = 1,65535,1,5
AT+TDC=30000
Five minutes after AIS01-LB is connected to the network, You will receive a payload containing a battery, five times and five meter readings corresponding to the time.

Example: Payload:

0A8C 663C66C6 02000000 3CAE0100 663C65D6 02000000 7A0F0200 663C6612 02000000 3CAE0100 663C664E 02000000 3CAE0100 663C668A 02000000 3CAE0100

2.3.4.1 BAT- Battery information

These two bytes of BAT include the battery state and the actual voltage.

Ex: 0x0A8C= 2700 mv

2.3.4.2 SysTime Current

Because this is data from five different times being combined together, it needs to be distinguished.

Ex:

0x663C66C6E="2024-05-09 06:01:42",

0x663C65D6= "2024-05-09 05:57:42",

0x663C6612="2024-05-09 05:58:42",

0x663C664E="2024-05-09 05:59:42",

0x663C668A="2024-05-09 06:00:42"

2.3.4.3 Integer

The five data points of Integer are: 02 00 00 00

Notice that the packet order is reversed here.

Ex：0x02000000=0x00000002=2

2.3.4.4 Decimal

Notice that the packet order is reversed here.

Ex:

0x3CAE0100=0x0001AE3C=11014

0x7A0F0200=0x00020F7A=135034

0x3CAE0100=0x0001AE3C=11014

0x3CAE0100=0x0001AE3C=11014

0x3CAE0100=0x0001AE3C=11014

2.3.5 Datalog FPORT=6

After turning on the ACK function, AIS01-LB will store every piece of data. When AIS01-LB is unable to upload data to the platform at the set time due to network fluctuations at certain times, AIS01-LB will store the collected data into flash. When AIS01-LB joins the network, the data will be packaged and sent to the platform.

FPORT 6 is somewhat similar to FPORT 4 with only two bytes less data about the battery.

Example of Device Status: 664809FC000000020006BF6F 66480A38000000020007A120

2.3.5.1 SysTimeCurrent

These four bytes contain the year, month, day, hour, minute, and second of the time.

AI Sensor use Unix TimeStamp format based on.

Users can get this time from the link:  https://www.epochconverter.com/ :

0x66482503="2024-05-18 01:53:00"

0x6648253F="2024-05-18 01:54:00"

2.3.5.2 Integer

The two data points of Integer are: 00000002

Ex：0x02000000=0x00000002=2

2.3.5.3 Decimal

These four bytes display decimals on the digital wheel.

Read table decimals：0x0007A120/1000000= 0.5

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

3.3.2 Get Device Status

Send a LoRaWAN downlink to ask the device to send its status.

Downlink Payload: 0x26 01

Sensor will upload Device Status via FPORT=5. See payload section for detail.

3.3.3 Set Interrupt Mode

Feature, Set Interrupt mode for GPIO_EXIT.

AT Command: AT+INTMOD1,AT+INTMOD2

Downlink Command: 0x06

Format: Command Code (0x06) followed by 3 bytes.

This means that the interrupt mode of the end node is set to 0x000003=3 (rising edge trigger), and the type code is 06.

• Example 1: Downlink Payload: 06000000      --->  AT+INTMOD1=0
• Example 2: Downlink Payload: 06000003      --->  AT+INTMOD1=3
• Example 3: Downlink Payload: 06000102      --->  AT+INTMOD2=2

3.3.4 Request the server to send an ACK

AT Command: AT+PNACKMD

  Downlink Command: 0x34

0X34 01    // Same As AT+PNACKMD=1

0x34 00    // Same As AT+PNACKMD=0

3.3.5 Print data entries base on page

Feature: Print the sector data from start page to stop page (max is 416 pages).

AT Command: AT+PDTA

Downlink Command:

No downlink commands for feature

3.3.6 Clear Flash Record

Feature: Clear flash storage for data log feature.

AT Command: AT+CLRDTA

Downlink Command: 

No downlink commands for feature

3.3.7 Clock logging

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)

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.

7. FAQ

7.1 Why does AIS01 automatically restart at every hour?

Please update the firmware, this issue is fixed in version 1.0.2.

7.2 Why is FPORT = 2 only 14 bytes?

Because this is the most primitive firmware version without the fifteenth byte, the fifteenth byte of the new version is used to detect whether the camera is connected correctly.
