First, we have to decode the name. "SPP" typically stands for or a variation of treated paper cone technology. In a world obsessed with rigid metal cones and ceramic drivers, the JL-SPP doubles down on the oldest material in the book: paper.

For developers and engineers who want to implement SPP functionality on JieLi hardware, the process involves:
This is the most common question users ask, and the answer is simpler than you might think: .

An Acer user noticed a "JL_SPP device" in the "Other devices" category. The device was "started" and showed no error, but the user was concerned whether it was a valid driver or a Trojan. USB Type-C and Controller Bus Freezes First, we
This technical background explains why a generic Windows driver cannot work with such devices: each JieLi implementation may use custom UUIDs, proprietary data formats, or specialized command sets.
A legacy yet highly reliable Bluetooth profile that replaces physical RS-232 serial data cables with a wireless connection.
As of 2025, Jieli has begun migrating many of its newer chips (e.g., AC700 series) to standards, which are natively supported by Windows without extra drivers. However, hundreds of millions of legacy devices (smart speakers, kids' toys, Bluetooth dongles) still require the classic jl-spp driver.
This is normal behavior. The JL_SPP entry may appear and disappear based on what Bluetooth devices are within range and advertising their SPP services.
