bluetooth lowenergy - Why the App doesn't reconnect to the BLE device when set autoConnect to true in Android? -

-

i develop in android , ble. want app automatic reconnect ble device after ble device disconnect come in range , advertising.

i use following code connect ble device:

public void connect(final string address) {         // todo auto-generated method stub         log.w(tag, "bluetoothleservice connect function.");         if(mbluetoothadapter == null || address == null){             log.w(tag, "bluetoothadapter not initialized or unspecified address.");             //return false;         }          final bluetoothdevice device = mbluetoothadapter.getremotedevice(address);         mbluetoothgatt = device.connectgatt(this, true, mgattcallback);      }

i have set autoconnect true , didn't reconnect when ble device has disconnect , come in range.

why app doesn't reconnect ble device when set autoconnect true in android?

did missing ?

thanks in advance.

the auto connect parameter determines whether actively connect remote device (or) rather passively scan , finalize connection when remote device in range.

but not mean peripheral that's been disconnected days reappears reconnected.

generally, first ever connection device should direct (autoconnect set false) , subsequent connections known devices should invoked autoconnect parameter set true.

also please note, auto connect work when device still broadcasting. if not, not work.

i prefer re-connect manually when device disconnected. if in case end following this, need marker determine whether device disconnected without user consent.

if true unbind/unregister service/broadcast receiver , connect again using device address must have saved previously.
