RTK station after firmware 1.16.1.2: a blinking blue light and "RTK Reference Station Is Not Ready"

Owners who updated the RTK reference station to 1.16.1.2 in September 2026 saw its light blink blue or go out, and the app report the station not ready. Cutting the station's power for a few minutes brought it back for most of them.

What to do next

  1. Power the mower down, then cut the power to the RTK station for a few minutes and plug it back in. Watch the station's light: owners saw it blink green and then settle on solid green within a few minutes.

    Applies when: the station updated to 1.16.1.2 and its light now blinks blue or stays off, or the app says the RTK reference station is not ready.

  2. Restart the mower and the RTK station. Then re-enter the station's LoRa number in the app, even if the app already shows the right number. A Mammotion account suggested re-pairing it, and an owner says someone else had success doing that.

    Applies when: the light is back but the app or the mower still shows the wrong positioning mode, or the station is still not ready.

    Worked if: the mower and the station pair again and the positioning mode switches as it should.

  3. Contact Mammotion support with the station's firmware version (1.16.1.2). Say what the light is doing, and add the app's log.

    Applies when: neither a power cut nor re-pairing brought the station back.

    Worked if: support has the version and the symptom together, which is what decides the next step.

  4. Tell us your mower and station model, the station's firmware version, and what brought it back.

Before you start: if your RTK station updated to 1.16.1.2 and its light now blinks blue or stays off, power the mower down and cut the station's power for a few minutes. That brought the station back for most owners here.

What owners report

  • A YUKA 1500 (2024) was prompted on September 21 to update its RTK station to 1.16.1.2. After the update and a restart the app showed "RTK Reference Station Is Not Ready" in orange, the station's light blinked blue, and the mower logged a poor positioning signal (error 1300). Powering the mower down and cutting the station's power brought it back1.
  • A YUKA 2024 with an RTK2 station had the exact same error. The same owner says their YUKA mini mowers, with RTK3 stations, updated without errors1. That is one owner's account of which stations are affected.
  • A station updated to 1.16.1.2 on September 22 blinked blue. After a restart it blinked green and then went dark, while the app still showed it connected with 28 satellites. After another restart, and turning off the "no work time" option, the light came back on and the mower's position was fine2.
  • Two more owners in that thread got theirs back with a power cut. One left it off for a few minutes. The other unplugged the charging station, which in that owner's setup also powers the RTK station, waited five minutes, and watched the light blink green and settle on solid green three minutes later2.

What Mammotion says

A Mammotion account told one of these owners that restarting the mower and the RTK unit is often a helpful step after a firmware update1. It told another to restart the robot and the RTK unit, then re-pair the LoRa number in the app2.

If the light is normal but positioning is still poor, the station's placement is the next thing to check: see RTK base station placement. For the station's official firmware tool, see RTK reference station: official manual firmware tool.
