Multiple LoRa RA-02 sensors sending to one aggregator

Hello, Can I program multiple Arduinos connected with Lora RA-02 sending to one Arduino connected with a Lora RA-02 that acts as aggregator?

Yes.

srnet:
Yes.

How? Because the example code of Lora library is only for one receiver and one transmitter every time...

Well, if you provide details of what you actually want to do, as in describing your project, you might get some suggestions.

I have 2 Arduino pro minis connected with temperature sensors and Lora RA-02 and I want these measurements to send them on an aggregator which also use RA-02...

When you send the sensor data, have the first byte, of the buffer\payload represent the sensor number.

What exactly does the 'aggregator' it do with the data it receives ?

It is connected to the laptop through the Serial to get the measurements.
