Lora recently looking at some of the data, and she is DIY the two small board, send and receive the lora function, want to make a multicast transceiver based on this, also is the star network, we call center gateway nodes,
Terminal side and gateway side intends to use the same module, because there are multiple needs and terminal connected to the gateway, unable to understand the following problems:
1. LORA network principle, whether the same time should be the one and only one terminal can nodes and even? Other nodes cannot be connected to the node,
2. If 1 is true, the other terminals are connected to the node implementations how? Let lora before connection terminal into sleep mode?
3. If you press 2, end up, how to implement each terminal can be connected to a node? Because each terminal bad wake up of time control,

Colleagues in the research of LORA, please help solve, thank you very much,

Connection is the concept of software, read the agreement how to design, from wireless point can be launched at a moment when there is only one, or it will conflict, usually by means of carrier sense, when the channel is busy, wait for a random time again hair,
