G-NiceRF LORAWAN System test -LORAWAN gateway and multiple LoRaWAN nodes transmit and receive simultaneously   


 

1-Test Objective 


 Verify if the LoRaWAN gateway can receive the data from the 8 LoRaWAN node simultaneously. 


2-Test flow diagram 


3-Test principle



PC1 transfer the data to RF module (LoRa6100) via UART.And LoRa6100 transmit the data to 8pcs RF receiver module transparently. And the 8pcs RF receiver send the data to 8pcs LoRaWAN node (LN610) separately which connected to RF receiver.It means the 8pcs LoRaWAN node receive the data at same time and transmit the data to LoRaWAN gateway simultaneously.And display on PC2.



Test method 


A, Connect one LoRa6100(as RF transmitter) to computer via serial port and using the Accessport software .LoRa6100 send out the data from computer via RF.                              

 




 B,Set 8pcs  LoRaWAN node(LN610) in different channel . And connect the 8pcs LN610 to 8pc LoRa6100 separately.LoRa6100 do the job of RF to UART.And LN610 get the data from UART,and send out  the data under LoRaWAN protocol 


C, Connect the LoRaWAN gateway (LG1301_SE) to computer. And log on the LoRaWAN device using putty.exe,and run lora_gw_start.sh(It can display the data that  LoRaWAN gateway get from the node)


 D, Transmit the data via Accesprot software.When the RX module get the data,the Blue LED will flash.And when the LoRaWAN node transmit data ,the red LED will flash.


E, If the LoRaWAN gateway(LG1301_SE) receive the data succesful,you can see the data from the 8 different channle on putty.exe


 

 


4-Test conclusion .


On the normal working environment ,set 8 LoRaWAN node on different channel,the LoRaWAN gateway can receive the data from the 8 LoRaWAN node simultaneously
