A driver is a small piece of software that acts as a translator between your computer's operating system and your physical hardware.

The provides the software required to fix missing "Other Devices" errors and stabilize connections between Windows computers and Bluetooth hardware built on JieLi (JL) microchips. When users notice a yellow exclamation mark or a grey question mark next to JL_SPP in the Windows Device Manager, it means the operating system is missing the virtual serial port profile required to communicate with a connected Bluetooth device, such as budget wireless earbuds, speakers, or development boards.

Open Device Manager , expand the Ports (COM & LPT) section, right-click the JLSPP port, and select Properties . Under Port Settings , click Advanced and change the COM Port Number to an unused slot (e.g., COM3 or COM4). Immediate Disconnections (Dropouts)
