how i can make wireless communication between multiple Arduino without ip ?

i have a project and i need to connect multiple Arduino wireless in specific range without ip so please give me an idea that can help me :confused:

search this forum for NRF24L01 to see if it matches your requirements.

Thank you but nrf24l01 need ip address.

The nRF24L01+ modules do not use WiFi or the Internet Protocol so they do not need IP addresses.

Have a look at this Simple nRF24L01+ Tutorial

If that does not meet your needs then you need to explain in more detail what you are trying to create.


i have many car and i need to make communication between cars in exact rang but i dont know its number so i dos not need to ip and all car send and receive the data .

Looks like we have an X-Y Problem here.

Are these real cars?
What is this specific range, yards or miles?

It looks like what you are trying to do is to emulate a cell phone, so why not use a cell phone, it will be much cheaper.

do you know v2v technology
