ESP32 A2DP Sink (BT Classic Receiver) based on ESP-IDF example. Currently tested on ESP32 DevkitC v4 (ESP32-4D0WD) with PCM5102 module. Builds and flashes via VSCODE ESP-IDF extension. Pairs and plays ...

This project demonstrates how to use an ESP32 to receive an integer via Bluetooth from a mobile device and then publish that integer to an MQTT server over a Wi-Fi connection. The project is a simple ...

Using Bluetooth on a desktop computer is now such a seamless process; it’s something built-in and just works. Behind that ubiquity is a protocol layer called HCI, or Host Controller Interface, a set ...

Typically associated with circuitry projects and real-time operating systems, microcontrollers are great for tinkerers who prefer working with embedded devices. But unlike their SBC counterparts, you ...

Transform curiosity into capability. The ESP32 by Example course, paired with the ESP32 by Example Kit (EEK) and Professor Jim Solderitsch’s guidance, teaches you the hardware, code, and systems ...

Security is hard. Just as Espressif Systems announced PSA Level 2 for the ESP32-C6 microcontroller, Spain-based cybersecurity company Tarlogic published their findings about a hidden Bluetooth ...

A recent controversy has emerged around Espressif’s ESP32 microcontroller, following the discovery of undocumented Bluetooth HCI commands by security researchers at Tarlogic Security. Initially ...

Espressif’s popular ESP32 microchip, found in over a billion devices, has been caught with its digital trousers down, thanks to an undocumented "backdoor" lurking in its Bluetooth firmware. For those ...
