My Spark has been working with mi issue for several months.  Today I after I turned on the RC it turned green for second but then turned back to red and started beeping.  The sticks would not engage the motor.  I turned on DJI go but the status looked normal.  The app could hook up to the drone with no problem - no problem that I could see. ????

Hi, we're sorry to know about this situation. May we know if your mobile device could still detect the wi-fi of your remote controller? If no, please try to reset the wi-fi of your remote controller by pressing and holding the power button of the remote controller for 9 seconds until hearing a toning sound like "DDD" and the Wi-Fi will be reset. If the mobile device could detect the wi-fi of the RC, kindly check if there will be an error message on the application. Please keep us posted on the latest progress. Thank you for continued support.
