What's the ideal scan window and scan interval of mobile phone for BLE device tracking and community searching?

[jonny0415]

I am developing a BLE anti-lost APP with community search, I set scan continuously or scan window 5 secs and scan interval 10 secs, but it drain phone's battery. How long does phone need to scan and to connect? I afraid if I set a long interval and short window will miss the devices and can not track them promptly.

Hi,

The "ideal" scan window and scan interval depends on your application and the current consumption requirements. The scanning window and interval you set are fine, but doing scanning one your phone shouldn't drain your battery that much. Have you checked that it isn't anything else turned on your phone, like other apps or GPS that is draining your phone? You can also try increasing you scanning interval.
