Do you want to check whether Bluetooth is active or not, or whether it is connected to a specific device?

You can use Serial.IsEnabled or BluetoothAdmin.IsEnabled to test whether Bluetooth is on. You can also turn it on with BluetoothAdmin.Enable.

Will be easier if you post the relevant code together with the question...

Do you mean that Serial.IsEnabled returns True after you turn off the Bluetooth device? Note that it might take a few seconds for the Bluetooth to actually turn off.

Seems like you are looking for BluetoothAdmin_StateChanged event.

Hi Erel

Q: Do you mean that Serial.IsEnabled returns True after you turn off the Bluetooth device?
A: Yes ! I true off the Bluetooth device ,the Serial.IsEnabled value is true at repeat 100 times .

Do you have any idea ?

Not really. Might be a OS bug. Which device are you using?

Try the StateChanged event. This is the recommended way to track the changes.

Seems like a device specific issue. The two methods suggested above are the standard way to check for the Bluetooth state.
