I have an iphone 6 running ios 11.2.6 which I'm attempting to use with an apple bluetooth keyboard. I can successfully pair the two devices, at which point the on-screen virtual keyboard disappears from text entry scenarios, so clearly the phone is expecting input from the keyboard. However, when I type, no keystrokes are received by the phone.
If I turn off the phone and turn on again the keyboard works as expected. Can anyone suggest a more elegant way of establishing the connection or maybe settings that might be interfering with the bluetooth functionality? Wifi maybe? This only seems to happen when I'm connected to a public (relatively slow) wifi.
