If after tuning you still get <500 KB/s, consider:
If you can tell me the (like a printer or graphics card) or the operating system you're using, I can make this review even more precise!
When the JL_SPP driver is missing, outdated, or corrupted, it leads to dropped connections, failed pairings, or that dreaded yellow exclamation mark in Device Manager. Making the isn't just about fixing a missing file; it's about optimizing your system for reliable, high-speed Bluetooth performance. Bottom line: jlspp gives you the speed and
If you are using GRBL (common for CNCs), adjust $1 (idle delay) and $110-112 (axis max rates) to match your new current and cooling setup.
It provides a virtual serial port over a Bluetooth connection, allowing legacy applications to communicate with Bluetooth-enabled hardware. Proprietary USB Communication:
