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
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.
