Why the APP shows that the RTK Reference Station is not added during maping?

(1) Confirm whether the RTK Reference Station has been successfully powered on, and the indicator will steady light if the RTK Reference Station is successfully powered on and the signal is good.
(2) If the RTK Reference Station is powered on and the signal is good, scan the code to match the RTK.
