This method won't install a named driver, but it can successfully install the necessary Bluetooth Enumerator to clear the error.

Scan any suspect driver with VirusTotal before execution.

The interface should be a simple, standalone window or a tab within the main software.

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.

Check if the driver has created multiple "Copy 1" versions in your settings. Delete the extras and set the original as "Default." jlspp driver link

Many laptop brands bundle the underlying Bluetooth stack fixes that resolve the JL_SPP error. If you are using a branded laptop, navigate directly to your manufacturer's support layout: JL_SPP Driver for ASUSTeK - X455YA - DriverIdentifier

Use this if this is an obscure Chinese or generic device (common for Arduino clones, USB adapters, or thermal printers).

When you pair one of these chips with a Windows PC, the device requests two protocols: an audio pathway ( JL_A2DP or JL_HFP ) and a data/programming pathway ( JL_SPP ). Windows natively manages the audio pathway smoothly, but often lacks a default proprietary data driver for the serial port profile, marking JL_SPP as an unconfigured "Bluetooth Peripheral Device". Why Is the JL_SPP Driver Malfunctioning? This method won't install a named driver, but
