Este proyecto consiste en dos programas para el microcontrolador ESP32 que permiten establecer una comunicación bidireccional con un dispositivo Android mediante Bluetooth clásico (SPP), simulando un ...
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 ...
Industrial controls have evolved from the days of hardwired relay logic-based units to sophisticated internet-connected systems. Legacy-based machine controls’ intelligent processes were configured ...
Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...
This weekend at the Bay Area Maker Faire, Arduino in conjunction with SiFive, a fabless provider of the Open Source RISC-V micros, introduced the Arduino Cinque. This is a board running one of the ...
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 ...
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 ...
Update 3/9/25: After receiving concerns about the use of the term 'backdoor' to refer to these undocumented commands, we have updated our title and story. Our original story can be found here. The ...
