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… ...

Besides the obvious advantage of enabling Bluetooth capabilities for your Home Assistant interface, an ESP32-powered proxy allows you to control and automate smart devices over a large area.

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 ...

Lurks in its Bluetooth firmware 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 ...

Tarlogic found hidden Bluetooth HCI commands in the ESP32 that could comprise its security by allowing read/write to the RAM and flash.

Reports of undocumented Bluetooth HCI commands from ESP32 chips are doing the rounds. They open up a security flaw.

Arduino has introduced a Nano shaped board with a Wi-Fi and Bluetooth LE capable Espressif’s ESP32-S3 microcontroller, supporting it with the Arduino IDE and MicroPython. “Beginners can explore in an ...

ESP32-S3 relies on the same 240 MHz LX7 core as ESP32-S2, except it comes with two. Since it’s a dual-core processor and supports both WiFi and Bluetooth LE it’s more comparable with the original ...
