How to use LoRaWAN Gateway LG1301-SE

LG1301-SE is the LoRaWAN gateway. It works with LoRaWAN node LN610 only. It integrates Standard LoRaWAN protocol V1.0 Class C.  

NiceRF: How to use LoRaWAN Gateway LG1301-SE

1. Power on of LoRaWAN Gateway

After powered on, the power led will light on to indicate, the LoRaWan gateway start the initialization. After 15s, the Tx LED will blink once to indicate the Linux system is ready, and then 5s later , the status LED will blink once per second which indicate the whole system is ready. Then it enters the normal working mode.

2. Normal Working Mode of LoRaWAN Gateway

In normal working mode, when payload is inputted to LN610, LN610 will transmit the packet to LG1301-SE automatically. After LG1301-SE received the data, it will output the payload in uplink format by serial interface.

When payloads with downlink format are inputted to LoRaWan gateway LG1301-SE.

LG1301-SE will transmit the packet automatically. LN610 will compare its Device Addr with the received packet. If the Device Addr is match, it will output the payload by serial interface.

Uplink/downlink format (All the data are in HEX format)

Uplink format:  ( Data from the node to the gateway )

Header ( 5 bytes) + Length ( 1 byte) + Device Addr ( 4 bytes) + Payload + Frame end (2 bytes)

Header: fixed to “$lora”;

Length: payload length + 4

Device Addr: MSB, Target Device Addr, only the product with this Device Addr will receive the message when send downlink packet.

Frame end : fixed to 0x0d 0x0a

Example:  

LN610 input hex data:

AA BB CC DD EE FF

LG1301-SE output hex data:

24 6C 6F 72 61 0A 01 B9 EC DC AA BB CC DD EE FF 0D 0A

Parse:

24 6C 6F 72 61 --------------------- Header

0A   --------------------- Length

01 B9 EC DC   --------------------- Device Addr

AA BB CC DD EE FF --------------------- Payload

0D 0A --------------------- Frame end

Downlink format : (Data from the gateway to the node)

Format:  Device Addr ( 4 bytes) + payload

Example:

LG1301-SE input hex data:

01 B9 EC DC 11 22 33 44 55 66

LN610 output hex data:

11 22 33 44 55 66

Parse:

01 B9 EC DC   --------------------- Device Addr

11 22 33 44 55 66   --------------------- Payload

Note:

The LN610 must join the network before communicate with LG1301-SE.

3. Setting mode of LoRaWAN Gateway

In normal working mode, press SET key to enter setting mode. The status LED will be turned on to indicate. Press SET key again to exit setting mode and back to normal working mode, the status LED will blink once per second to indicate.

User can use our specified PC software to configure LoRaWan gateway LG1301-SE.

Below is the PC software interface.

In setting mode , the gateway supports three operation on node.

• Add node into the network

User input the Device Addr、NwkSKey and AppSKey of node. Click [Add Node] button , then the node will be added into the network.

Note: The Device Addr、NwkSKey and AppSKey of node can be read out in PC software of node.

• Delete node from the network

Input Device Addr in block ”Delete node”，and click [delete] button，then the node with this Device Addr will be deleted from the network.  

Once the node is deleted from the network, the gateway will ignore all the information from the node and won’t send message to the deleted node.

• Read out the node list of the network

Click [ Read ] button can read out the node list.

When PC software opened, the node list will be read out automatically.

4. Parameters for LoRaWAN Gateway 

UART : 115200, 8, N, 1

Tx power : 23dBm

Tx frequency and Data Rate:

Receive Frequency channel :

Note:

The Tx rate of LG1301-SE is fixed as the Rx rate of LN610, the Rx data rate of LG1301-SE is not fixed which match to the LN610’s Tx rate automatically.

The Tx frequency of LG1301-SE is fixed, but it can receive the data from all the 8 channel simultaneously.

The maximum MACPayload size length (M) of LG1301-SE is 51bytes, the minimal Tx time interval is 2s.
