I'm almost done with my project but everything is fine as long as they are in the same room.
I am using radio frequency 868.
However, I have noticed that putting the Tx in a different room the signal drops drastically, if I put it on the lower floor it is really difficult to communicate.
Is there a way to increase the range?
I use LAUNCHXL antennas, radio frequency 868 with 50kbps.
Thank you
