Lora Multiple Nodes

Hai, I am using Lora Ra 01 ISM803-930Mhz , planning to using single receiver and multiple transmitters, If I start all the transmitters at a time the receiver receiving only one transmitter data, and also need a continuous transaction, Over all concept is sending single sensor data from different location, I am not using duplex, Help me

Thanks in Advance

Perhaps explain what the project is, its purpose, where it is etc.

You need to provide details on what you mean by 'continuous transaction' as the forum does not know, how much data, how often, how fast, how many nodes etc.
