Overview
Description
A typical BT840 module provides:
- A Bluetooth radio (Classic and/or BLE)
- A host interface (usually UART; some variants offer SPI/I2C)
- Onboard MCU/firmware for basic processing
It’s used to connect microcontrollers to other Bluetooth devices for data, sensors, audio, HID, etc., and usually supports pairing, security features, and common profiles (e.g., SPP, GATT).
Power: designed for low-voltage operation with sleep/low-power modes for battery apps.
Configuration: often via AT commands or an SDK; firmware updates are usually possible over UART or a dedicated DFU mechanism.
For a precise introduction, please specify the exact BT840 model and vendor (or share a datasheet/link).
Features
- Bluetooth type: Classic, BLE, or both; supported profiles vary (e.g., SPP, HID, A2DP, AVRCP, HFP for Classic; BLE GATT for BLE)
- Version: depends on variant (e.g., BT 2.x/4.x/5.x)
- Interfaces: UART (AT commands), plus SPI or I2C; GPIOs; PWM
- Power: typical 3.3V supply (some variants support 1.8–3.6V); sleep/low-power modes; current consumption varies
- Range: Class 2 (~10 m) or Class 1 (~100 m), depending on module
- Development: AT command set or SDK/API; firmware updates available on many models
- Memory: on-board flash/RAM (size varies by variant)
- Security: pairing/bonding, encryption options
- Certifications: CE/FCC/IC (and RoHS) depending on variant
- Optional: audio features (A2DP/AVRCP, mic/line-in) and MCU GPIO expansion on some versions
