Multipoint to point communication

[AHakk.1]

Hi everyone, I want to use 50 sensor device and 1 base station. I look stm32wl topics and I can't find the way. I watch hands on tutorial MOOC - STM32WL workshop - 4 Point to point Phy layer application lab. He really well explained for beginners (I am). I want to send these sensor nodes to the internet so my base station needs internet connection too. What is the proper way to do it. Is there any other examples ?

Hello @AHakk.1​ and welcome to ST Community,

Have you checked this video ?

Hi @Sarra.S​ and thank you. I checked that video but it requires lorawan network. I don't want to use lorawan network (LORIOT,The Things Network etc.). I want my base station send datas to my http server (which requires http client).

I ordered 3 NUCLEO-WL55JC1 board and I can communicate 1 base to 2 sensor devices with linked video on question.

Hello AHakk.1  I also am wanting to use the WL33 for point to point comms without LoRaWan or Sigfox. Can you share how you did it?

Thank you!

The Ping-Pong example is one that demonstrates point-to-point (P2P), it's a relatively short walk to make a listener node, and ones that periodically sends.

Everything in range on a radio network can hear the transmissions of other stations, ie inherently multi-to-multi

Thank you Tesla, I found it. I'm a bit confused though. WL55 / WL33.  In the WL55 do you use only the M0+ then port to a WL33?

Sorry the thread was on the LoRa part, not the STM32WL33 which is a new one. I'd anticipate one could find the transmits and receive functions, as they won't be occurring concurrently, and transmit your own payloads, and use your own protocol.

Did you get the solution?
If you did, is it possible to share?

The Ping-Pong example suggested by Tesla will work. I am now waiting for ST to release the WL33 nucleo board along with a CubeWL33 firmware package. Its release is scheduled for q4 of this year I think.
