SX868 Range Problems

Hi,

This day i tested two SX868 Modules (Ref XB8X-DMUS-001).

Configuration :

  • 32mW Tx Power
  • 10kbps rate

Hardware :

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.

Adrien

Adrien,

What you are referring to is Visual LOS where by Digi is referring to RF LOS. To get a better idea of what Digi means, please go to https://www.digi.com/support/knowledge-base/maximizing-range and read the attached file.

Hi,

I have 4 modules of sx868 (XB8X-DMRS-001), I did a range test with it and I got only a 1-meter range. I don’t know why.

Tested with xctu tool.

Please, suggest if I can check anything. I have tested by reading the user manual.
