I have just bought a Sprocket 200 but it doesn't show up in my bluetooth settings.
I have followed the guide 100%, it's fully charged and everything but nothing helps - meaning I can't even update the firmware.
As far as I can understand, many people are experiencing this.
We have tried both on my iPad and my girlfriends' Huawei with no luck.
We bought the device with one purpose - using it at our wedding. Pretty frustrating 😞
