wtf is chimerable?

ChimeraBLE is a tool for exploring and testing Bluetooth Low Energy, or BLE, devices using an ESP32 microcontroller board. It can act in three roles at once. It can scan and connect to nearby BLE devices the way a phone would, it can pretend to be a BLE device itself so it can copy or imitate one, and it can sit between a real device and whatever it normally talks to, watching and recording the traffic that passes between them. Once connected to a device, ChimeraBLE can list every feature the device exposes, read and write its data, and listen for updates as they arrive. It can also decode information broadcast by nearby devices without even connecting to them, and it will often guess what a device is, such as a fitness tracker, a pair of headphones, or a smart appliance, based on patterns in the signals it gives off. It can read keyboard and remote control style devices and work out which buttons are being pressed. A direction finding mode lets someone walk around with the board and watch a signal strength indicator grow stronger while approaching a device, which helps with physically locating it. The project runs on a handful of small hardware boards, including one with its own screen and keyboard so it can be used on its own, and others that are controlled by typing commands over a serial connection from a computer. Getting it running involves building and flashing the firmware with a tool called PlatformIO, then typing commands to scan, connect to, and inspect devices. Because it can copy other devices, intercept their traffic, and pretend to be them, the project states plainly that it should only be used on devices someone owns or has clear permission to test, and that whoever uses it is responsible for following the laws that apply where they are.
