I am just starting with a few RFM69's. Thanks to the nice library for it, it was no problem to get some signals through the air. But, I have a few questions:
- do you need a vertical wire antenna? Or are there other good options? Maybe even a specific pattern for pcb? Without antenna the signal doesn't even get across the table.
- the examples are called node and gateway. But there is nothing special about the gateway I think? All nodes can communicate with each other without the need for a gateway as far as I understand it now.
- are these devices usable for driving something like an rc car? Or more interesting, a swarm of vehicles? There is probably a correct word for it, but I guess it comes down to respons time. Is it possible to send control signals continuously? Or will there always be a delay or dropped messages?
