Creating a LoraWAN server on an stm32 chip

I am making a device that is to take pulse outputs which have been converted to wireless LoRaWAN signals, and convert it back again into a hardwire pulse output. For the receiving device, I intend to use a modem board PN 109990166 connected to an STM32L476RG. Is it possible to make a simple LoRaWAN server on the stm32F4 whose primary purpose is to take the wireless data and convert it to pulse output? If not, what other wireless protocols would be good for this application? The transmitter doesn't have to be LoRaWAN.

LoRaWAN or LoRaP2P ?

Definitely had LRWAN library running on L4 and F4 parts.

Not really a Gateway, as that uses a SX130x part, which has multiple receive channels, to capture different nodes/bands. Software wasn't open.  https://www.st.com/en/evaluation-tools/p-nucleo-lrwan3.html

To create a board that can receiver LoRa radio signals, and generate pulse output, or servo PWM, something simple/singular like this would suffice.

The Ping-Pong example shows point-to-point communication, and that can be cut down to make one a transmitter, and one a receiver, without any gateway or server

Sorry, I meant to say stm32L4, not stm32F4

There's a 'V' icon to the upper right of the post, gives you a drop-down menu with an Edit option.

Nice, man! I am unfamiliar with the different kinds of LoRa options, and it looks like the LoRaP2P & this dev kit seems to be exactly what I need. Thank you!
