Bluetooth sniff mode interval
WebFeb 11, 2024 · Either device is allowed to exit sniff mode at any time. This is part of how classic Bluetooth is defined. I'm guessing that your target device's controller has a policy to automatically resume active mode at a certain data size payload. If you want a persistent connection with sniff characteristics, I suggest implementing a low energy ACL. Share.
