RSSI Setup Dragon Link

Posted by Kevin Garland on March 25, 2015 at 8:59pm

Ok I have the pixhawk and dragon link installed on my aircraft. What is the best way going to program my RSSI. I am getting a read out of 65 on my PFD and when I unplug the cable for RSSI I get 32. 

Dragon Link suggested putting the plane about 50-60 feet away on High setting and set it so it reads around 99. Then put the dragon link in range test mode and set the low. Do I adjust the RSSI Voltage parameter on Mission Planner? I played with it some on the high in and got it to show 99, but not sure how to adjust the lower end. Or is this even right?

    Hi I may found a way to help you:

    1. Connect DragonLink RSSI analog out, Pin8 to Pixhawk SBUS (SB).
    2. Connect the Pixhawk on your PC, open Mission Planner in  Full Parameter List and find the RSSI options PIN and RANGE to set the values below:
      1. RSSI_ANA_PIN: 103
      2. RSSI_TYPE: 1
      3. RSSI_PIN-HIGH: 3.3

    Dragonlink uses 3.3V RSSI.  Make sure you select that on your Pixhawk to get the proper range.

    WIth current firmware ("Next gen" from June or 2014 or later) the Dragonlink RSSI goes from 0-3.3V over the useable range.

    Dragonlink will be working fine with an RSSI as low as 10% or so which requires you to be many 10s of kilometers away with the stock antennas.

    I tweak the 100% value using the settings in the MinimOSD-extra firmware.
