STM32WL55_local_network_scaling_upto_30sensors

[mohansv]

Hi,

In this example,  https://wiki.stmicroelectronics.cn/stm32mcu/wiki/STM32CubeMonitor:How_to_start_with_STM32_Wireless_Long_Range_demo

there is a demo of one concentrator, and up to 15 sensors. How to perform the communication between one concentrator and up to 30 sensors in a local LoRa network concentrator setup, without LoRaWAN like the example shown in the link? What changes are to be done in the STM32WL55 local concentrator example code ? Please suggest. Thank you.

Hello @mohansv and welcome to the ST Community :smiling_face_with_smiling_eyes:.

What I suggest you is to use the available Sub_GHz examples on this STM32CubeWL. Then, you can configure one node as a concentrator and the other 30 as Clients. Then configure the communication as follow:

• The concentrator sends a message for the initiation of communication.
• All sensors receive the Message.
• After a specific delay. For example 3s for the sensor 1, 6s for the sensor 2, 9s for the sensor 3, ...
• After each delay, the sensor send data that will be received by the concentrator.

Best Regards.
