Im beginner, i have new dji spark (without remote control), at the first time i can connect the drone using ssid (i use android, LG q6+), i think after update firmware or something i cant connect to drone anymore, please help

Hi,

We apologize for the inconvenience. To reset the wifi, hold the power button for 9 seconds until you hear the aircraft beep three times. Please check the attachment for compatible devices of your spark.

To prompt detection, press and hold the power button for six seconds until you hear the aircraft beep twice. This indicates that Spark’s Wi-Fi is now detectable on your mobile device.

This will help too -
