Hello, I buy two https://www.sparkfun.com/products/18572, connected everything according to the instructions https://github.com/chandrawi/LoRaRF-Arduino the antennas are at a distance of 20 cm and the RSSI indicator is -96

Photos would be helpful. What antenna are you using? What’s the rssi when they are 20 or 100 meters apart with line of sight?
At 20 cm, the receiver input is probably overloaded.
