android 链接蓝牙不稳定的解决建议

My workaround

I scan BLE for a short period of time 3-4 seconds then I turn scan OFF for 3-4 seconds. Then ON again.

• Obviously I always turn BLE scan OFF when I'm connecting to a BLE device.
• When I disconnect from a device I restart BLE (turn adapter OFF and then ON) to reset the stack before starting scan again.
• I also reset BLE when discovering services or characteristics fails.
• When I get advertisement data from a device that the app should connect to (lets say 500 times without being able to connect - thats about 5-10 seconds of advertising) I reset BLE again.
