I have two XBP24-BZ7WIT for Point to Point Connection and configured them accordingly. The problem is that the range test in XCTU shows a low signal strenght when the modules are less than 1m away from each other (about -70dbm). With greater Distance (>5m) the connection gets completly lost.
I uses these breakoutboards to connect to the modules:https://www.sparkfun.com/products/8687
One is connected directly to the computer, while the other is mounted on a PCB, which is driven by an arduino. This should not have such a big impact on the signal quality, should it?
What can I do to get a good connection over a range from 10 to 1000m?
Is it possibly that a bad power supply causes that problem?
Thank you in advance
