Hi @carywin Which library is good for any network you want to build rfm69, RadioHead ? Does it make any difference in code?

When ever i am sending data using serial port from one to another. Data gets printed on serial port 2 to 3 times. I am using arduino uno. I am referring https://learn.sparkfun.com/tutorials/rfm69hcw-hookup-guide/all#res code.Here for Node 1 same code and for Npde 2 just swap value of MYNODEID and TONODEID.Here i am using 868MHz that i have already changed in my code.

Hi @mfalkvidd,
If you don't mind ,could you share your tree topology code?

Hi @mfalkvidd,
how can i make a simple mesh network which directly sends message to the concerned node and that node acknowledge to the main node from which that message has been received with or without a gateway ?

@mfalkvidd
Thanks for the reply. Not at all.I do not have any problem with this.

I am new to RFM69. I want to make a mesh network using RFM69 and Arduino. Is it possible to make this without using a gateway? Help me in the programming of this.
