      How to increase the power of the telemetry module

      In order to increase the output power of the telemetry module, and therefore the range of your WingtraOne, please use these instructions.

      Use these instructions only if instructed by Wingtra support!

      Before starting the procedure, check which telemetry frequency (868 or 900 Mhz) your WingtraOne uses, and use the appropriate parameters. If you are not sure on which frequency the drone is, contact Wingtra support.

      The procedure for 900 Mhz units is only possible if an older version of the tablet (Samsung Galaxy Tab A) is used.

      Caution:

      • Deviating from the described procedure can lead to damage to WingtraOne’s electronics
      • If the procedure fails, it is very difficult to restore the correct configuration remotely
      • If the procedure fails WingtraOne will not take off

      Required equipment:

      • WingtraOne
      • Flight battery pair
      • Samsung Galaxy Tab Active 2 or Samsung Galaxy Tab A tablet (charged) with internet connection over Wifi
      • Telemetry antenna with cable to connect to the tablet
      • The following instructions

      Step-by-step procedure

          CAUTION - IT'S VERY IMPORTANT TO KEEP THE EXACT COMMAND AND ORDER of the following commands. (Note: the results of the commands are visible in the main interface of the program.)
          1. Type the command RTI5 and press send
            1. It should print out an entire list with 18 lines
          2. Type the following commands based on your unit:
            1. For 868 Mhz units
              1. RTS4=27 and press send
              2. ATS4=27 and press send
            2. For 900 Mhz units
              1. RTS4=30 and press send
              2. ATS4=30 and press send
          3. Confirm the settings
            1. Type the command RTI5 and press send. The value for parameter S4 should be:
              [0] S4: TXPOWER=27 (for 868 Mhz units) or TXPOWER=30 (for 900 Mhz units)
            2. Type the command ATI5 and press send. The value for parameter S4 should be:
              [0] S4: TXPOWER=27 (for 868 Mhz units) or TXPOWER=30 (for 900 Mhz units)
            3. BOTH replies should contain the very same parameter on S4!
          4. ONLY IF BOTH replies are the same, proceed with step 12.  If they are not the same for RTI5 and ATI5 then repeat from step 11b.
        12. Store settings permanently:
          1. Type the command RT&W and press send
          2. Type the command AT&W and press send
          3. Type the command RTZ and press send
          4. Type the command ATZ and press send
        13. You should observe incoming scrolling green characters
          1. IF NOT please inform support on wingtra.com/support
          2. IF YES proceed
        14. Close the connection to the telemetry module in the Serial USB Terminal app by clicking the connection button in the top right (next to the bin)
        15. Disconnect the telemetry antenna cable from the tablet
