Btlejack provides everything you need to sniff, jam and hijack Bluetooth Low Energy devices. It relies on one or more BBC Micro:Bit. devices running a dedicated firmware. You may also want to use an Adafruit’s Bluefruit LE sniffer or a nRF51822 Eval Kit, as we added support for these devices.
Current version of this tool (2.0) supports BLE 4.x and 5.x. The BLE 5.x support is limited, as it does only support the 1Mbps Uncoded PHY and does not support channel map updates.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
