I've searched a lot for a good simulator software to teaching IoT structure to students.
I need a software which has a lot of features for testing like "IoT Gateway", "Broker", "Smartphones or clients" etc.
Also, it's important that they could work with MQTT, Lorawan, LPwan, etc.
Cisco Packet Tracer is a great device for teaching the backbone of network and internet. I need something like this.
If it could, we could cooperate to create this kind of software.
Any insight and ideas would be appreciated.
