I have a Hubsan X4 Star Pro purchased from The Source recently. My phone is an ACER Liquid Zest Model T06. Android version 6.0 and Bluetooth 4.0.
The Android App works perfectly for the FPV, GPS, Maps, and virtual control of the drone. I am very impressed with this drone package.
The only problem is the HT009 controller won't pair with the phone. I know the phone's bluetooth works because it pairs with numerous other bluetooth devices. I have gone to the settings in the X-Hubsan App, then Controller, scrolled down to Using remote control, it finds the remote's transmitter, I select it and press connect. "bluetooth connection fail" flashes after about 20 seconds. I have tried a factory reset on the phone, and removing and installing the remote's batteries.
Nothing works. Any help would be appreciated.
