I make a lorawan simulator on this git : GitHub - UniCT-ARSLab/LWN-Simulator: A LoRaWAN nodes' and network simulator that works with a real LoRaWAN environment (such as Chirpstack) and equipped with a web interface for real-time interaction.
and also make chirpstack on this git : GitHub - chirpstack/chirpstack-docker: Setup ChirpStack using Docker Compose

but after make the device and gate way on simulator

and make device and gate way on chirpstack with same mac address but the gate way and device is not active
