The is a compact USB Bluetooth adapter. It typically utilizes Bluetooth versions ranging from 5.0 to 5.4 depending on the specific sub-model iteration. It boasts features like an extended transmission range (typically up to 20 meters), higher transfer speeds (up to 3 Mbps), and lower power consumption. Key features include:
This guide covers identification, driver sources, installation, troubleshooting, configuration, firmware, and development details for devices identified as “bm05e-v2 01” (BM05/BM05E family Bluetooth modules and their Windows/Linux/macOS drivers). It assumes the BM05E is a USB-attached Bluetooth adapter or USB-serial adapter built around common CSR/Realtek/ameba-like chipsets or a module flashed into USB-serial mode. If your hardware differs (e.g., integrated SoC on a development board), the recommendations still apply but map chip-specific steps as noted below.
There is a 90% chance this device uses one of the following three chipsets:
