transmitting through packets from arduino to another arduino

Projects Programming

Hi!
I am working on lifi communication & came across thought that we always use packets of data to transmit while using internet....so I thought that can we make packets by using arduino code in arduino...
I thought I should make 100 bit packet size & send it to reciever.....
Is transmitting through packets possible by arduino?if so how?

Is transmitting through packets possible by arduino?

Yes. The ethernet library does that.

Yes. The ethernet library does that.

the Wire library too.

a basic packet envelope is address and length of data.

plz send a syntax of code for packet size ...

Please use proper spelling and capitalization. YOU define the packet, which then has a size. You measure it.

sender
out.write(l); // send the length
out.write(buff, l); // send the data

reciever
size_t l = in.read(); // read the length
in.readBytes(buff, l); // read the data

i really appreciate ur help...thnx

sender
out.write(l); // send the length
out.write(buff, l); // send the data

reciever
size_t l = in.read(); // read the length
in.readBytes(buff, l); // read the data

so what do u think what exact length & buffer size should be used for sending 100 bits of packet size....
