BT keyboards = key loggers delight. Another possible security exploit. Wonderful thing for a critical device where you type your life.
Yeah, they can just keylog my vulgar history. Cmbucket, cream pie, turtle p0n0s, milk, etc.
Or you can easily make Faraday's cage for your working space.
I assume with your security concern, you don't type critical part your life in a cafe or public area don't you? Unless being a hipster, bringing TKL keyboard everywhere.
Joking aside, they can use
this instead, a sure method to get your life. Probably they can just tap router as well.
==================================
I wonder if someone already got and undress this baby.
I'm curious about the nrf51882 they're using.
This module they're using is more open than Broadcom's so it has higher chance to make your own layout or cannibalize to make your own BT keyboard.
