Characteristic - Insufficient Encryption

[adras]

I'm trying to explore a bluetooth device, however on some characteristics I see the error "Insufficient encryption". If I use a similar app on android, it's able to show me those characteristics.

Is there a way to add encryption?

Have you paired with the device? Once your device is paired, the connection will be encrypted.

I just double checked, yes it is paired.

Any update on this? Even when the device is paired I get the error "Insufficient encryption" on some characteristics on my device.

Im having the same Issue, I once managed to get a secured connection with my BLE device, where everything worked fine. Once I tried to redo it it never worked again.
I tried to pair it via the Application as well as in the Windows settings. As far is I could figure this out these are the only options you have to pair a device in Windows.

Device I tried to connect to is a Philips Hue RGB Lamp.

any advice on how to set up the secure connection ?

Seems like

BluetoothLEDevice.ConnectionStatus.WasSecureConnectionUsedForPairing

is now no longer supported. But if you connect with:
DevicePairingResult result = await DeviceInfo.Pairing.PairAsync(DevicePairingProtectionLevel.Encryption)

then:

result.ProtectionLevelUsed
will be None

The default-mode which is normaly used upgrades the ProtectenLevel, if a higher one is supported. But it seems like those devices don't do that, why?

Same Philips Device as Gongxter has. You can also see: Read Not Permittted everywhere.
