This day i tested two SX868 Modules (Ref XB8X-DMUS-001).
- 32mW Tx Power
- 10kbps rate
- SX868 PC Module with 2dBi Antenna
- SX868 Autonomous Module with 6.2 dBi Antenna
I performed a range test but after a range of 300m+, my reception is very poor (<5%).
The trials were performed on a flat environment (on water) with XCTU software.
One SX868 is 5m above the water surface.
One SX868 is 0.5m above the water surface (no swell)
In your doc, i found a THEORETICAL LINE-OF-SIGHT RANGE Up to 14.5 km w/ 2.1 dBi antenna
I don't understand why my range is reduced like that.
Thank's for you help.
