Hi all,
I have a friend who has asked me to design a radio link for simple on/off control at 868MHz.
Now I've never even looked at this before so I'm unsure as to a simple solution.
I've seen data transceivers on ebay, but what would be best, I assume a simple data stream would be adequate.
If anyone has any idea of a suitable pair of +10dbm modules please post the details. I'm somewhat confused by the choice, with some as rs232 others mentioning uart etc.
The idea is to send to a remote location a signal to turn on/off an output. That's it, nothing fancy.
In software I guess a unique ID then a code to select the action. I also considered as I was considering a transcever pair, a signal back to confirm output selected.
