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 ?

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.

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.
