The BL12A3 is a Bluetooth 5.0 module designed for low-power, low-cost applications. It's based on the Nordic Semiconductor nRF52832 microcontroller, which provides a robust and reliable platform for wireless communication. The module supports a wide range of Bluetooth profiles, including SPP (Serial Port Profile), HID (Human Interface Device), and BLE (Bluetooth Low Energy).
Based on technical documentation for smart home and audio accessories, is the Bluetooth device name used for integrated speakers in luxury furniture items like LED mirrors from manufacturers such as Artforma . Connection Instructions
Q: What is the power consumption of the BL12A3 module in sleep mode? A: The power consumption of the BL12A3 module in sleep mode is <100μA.
For engineers and hobbyists: Purchase a with a 3.3V regulator and pin headers. Connect it to an Arduino or USB-to-UART adapter (e.g., CP2102). Send AT commands via a serial terminal at 9600 baud. Within minutes, you can establish a wireless serial link to your phone using a Bluetooth terminal app.
: If you receive a phone call during music playback, the module automatically pauses the music and switches to the phone; it resumes playback once the call ends. Standard Pairing
(Warm, Natural, Cool) with adjustable brightness via touch sensors on the mirror's surface. Connectivity
