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 ...

This project enables audio streaming to the PYNQ Z2 board via Bluetooth using the ESP32. The ESP32 connects to the PYNQ Z2 board via the PMOD connector, and audio is sent through I2S to the ADAU1761 ...

The project's main goal is to offer the user the possibility to stream music over Bluetooth to ESP32 which will forward the received music to a DAC (Digital-to-Analog Converter). Thus, this project ...

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 ...

Recently there was a panicked scrambling after the announcement by [Tarlogic] of a ‘backdoor’ found in Espressif’s popular ESP32 MCUs. Specifically a backdoor on the Bluetooth side that would give a ...

The cheap WLAN and Bluetooth chips from the manufacturer Espressif, ESP32, contain undocumented commands in the Bluetooth hardware communication in current firmware versions. This opens up a security ...
