BKK Hardware

BKK currently manufactures two pieces of hardware with bluetooth capabilities.

BKK Cup

The BKK Cup is a onahole style stroker/masturbator with an accelerometer and buttons built in. There is no output or haptic actuation in the toy, it is only used as a controller for either games or movies.

BKK Bracelet

Note: BKK Bracelet implementation here is speculation taken from ad copy on the product website, we do not actually have a BKK Bracelet on hand at the time of this writing.

The BKK Bracelet is most likely the same circuitry as the BKK Cup, except in “bracelet” form. It probably contains the same accelerometer and button setup, allowing users to attach it to the onahole of their choice.

Chipset and Implementation Details

Due to the service IDs and identification of the BKK Cup, it is assumed that this is a TI CC2540 Reference Kit Design. In fact, it may using a reference keyfob implementation available on github. This is apparently a common reference design to copy, as it has also been found in lightbulbs.
