Dev Lab - CircuitPython Bluetooth Find Me - Silicon Labs
This project-based Dev Lab steps through the creation of a Bluetooth Find Me device using CircuitPython on the Silicon Labs EFR32MG24 secure, connected, microcontroller. The completed software operates as a key finder type device playing alert tunes using a passive piezo buzzer when activated. Activation can be triggered from a mobile phone using the EFR Connect application, now called Simplicity Connect, or by pressing a button on another Find Me device. The device operates in both target and locator modes as defined by the Bluetooth SIG Find Me Profile.
