LocalNetwork Concentrator-Sensor Connection issue

[JeffSm]

Hi, I tried the LocalNetwork demonstration in which one NUCLEO board acts as a concentrator and other NUCLEO boards act as sensor unit. Its available in STM32Cube_FW_WL_V1.0.0/Projects/NUCLEO-WL55JC/Demonstrations/LocalNetwork

I loaded and ran one NUCLEO board with LocalNetwork_Concentrator and one NUCLEO board with LocalNetwork_Sensor code. But my sensor NUCLEO board is not able to receive the beacon sent by the concentrator. I am not sure why this is happening. I have also attached the terminal image. Can you please guide why is the sensor not receiving the beacon?

Hi,

The LoRaWAN_End_Node application is LoRaWan compliant project application.

Therefore, it follows the LoraWan Alliance specification in particular the Regional Parameter specification.

The Preamble format is defined in this document and hence its length is frozen.

For example for Europe it is defined as:

and is defined the same way for all regions

hope it answers your question.

Hi, Thanks for the reply.

Can you please share the document?

Also, is there any way to change the preamble time of a transmission from end node to receiver? Or the preamble time is also fixed?

Hi,

you can download the documentation from https://lora-alliance.org/
