[Steven_wang]

I use the demo : ble_app_proximity to connect with android app In android use this : mBluetoothGatt = device.connectGatt(mContext, true, mGattCallback); to set the reconnect true . but , when the ble_app_proximity connect with the app ,I take away the ble_app_proximity battery . and Power on again(the ble_app_proximity just adverting ,but It can't connect automatic with app.
How to make them connect automatic ?

Hi Steven,

What you trying to do is correct. However, I experienced that on some Android phones, it didn't work as it should be. My test here on Samsung Galaxy S4 Android 4.3 it will automatically reconnect after a timeout disconnection.

Which phone are you testing on?

we use Sansung Galaxy S4 Android 4.3 too ,but the connection seems no stable(if move the chip,it always go into disconnected,the distance maybe 5-6m)
