I have an RSSI problem with mbed LoRa Shield boards(SX1276MB1MAS). I’m using Arduino Uno with the Arduino-LMIC library.
This is my settings:
- output power: 14dbm
- BW: 125KHz
- SF: 7
- Channel: 868MHz (HF)
- and an antenna with 1/4 wave length, gain of 0.7dbi
When sending in a room no more than 1 meter apart, I get a RSSI of around 90 dbm.
I’m really confused and expected higher ranges in LoRa.
I would appreciate your assistance with this RSSI problem.
