I have been trying to make something like this picture
Multiple MKRWAN 1300 devices will send sensor values to the gateway device and it will be shown in server. (I mean on Website or something similar). And user might want to change something in MKRWAN 1300 devices (end node), so end nodes had to receive function. So my question is how to specify that connection between gateway device and end nodes. I thought that gateway device will broadcast the data to end nodes and each end nodes will only connect to the gateway device. How to specify that. Is there any useful video or article about this problem?
Also can I use MKRWAN 1300 as a gateway device. Like now I can send data from one end node to another. So?
