Right-click the Start button and select Device Manager .
Even if you have not intentionally paired any device, your computer's Bluetooth radio might be scanning for nearby discoverable devices. If a neighbor or a nearby colleague has a Jieli-based device (like a pair of earphones) with its Bluetooth active and in a pairing or discoverable mode, your computer could detect its unique identifier and prompt for its driver, even though you never intended to connect to it.
Whether you are programming an AC692 for a custom IoT sensor, troubleshooting a barcode scanner, or simply trying to get a cheap Bluetooth module to talk to your laptop, understanding this driver will save you hours of frustration. Bookmark this guide, keep a verified driver file handy, and you will master the JL-SPP driver in no time. Until these chips fully transition to USB-CDC or
Do not use shady, third-party "driver scanner" websites to hunt down isolated JL_SPP.sys files. Doing so risks malware infections. Instead, download the authentic parent radio stack directly from your PC manufacturer's official deployment channel. What is this JP_SPP driver? - Acer Community
